If you are using Rockwell control systems as a platform across your facility or if you have integrated systems between other vendors along with any Rockwell products, you may have found the need to cross multiple networks to gain communications between different systems that need to communicate with one another or you may need to access a controller across multiple networks.
Understanding how to bridge across networks using RSLinx is a valuable tool to have in your bag if the need arises.
I have found it useful in many instances dealing with system integration between vendors, bridging from one EtherNet network to another EtherNet network as well as bridging to a DLR (Device Level Ring) network.
A chassis like this one can be used to bridge different types of networks:

In the following illustration, the EN2TR module in slot 4 does not see any other networks or modules available as they are in a DLR configuration.

In order to “bridge” to the DLR network, you must manually configure the EtherNet addresses for the additional network. Right-Click on the module and Select “Properties”

Manually select the IP addresses of the network devices that you need to have access to. Then Click the “Add” button and “Apply” Buttons. Select “OK” to close the window.

You can now see the added modules in your RSLinx browser:

Other Considerations:
Manually added addresses are not backed up when using the “RSLinx Backup and Restore Utility”. If you restore an RSLinx Project, you will have to manually reconfigure the bridged or routed devices.
Conclusion
This tool is very versatile, so there is no exact architecture for its use. If you are new to Rockwell products, you may never have needed or used it before now and you will find it beneficial down the road.
I used ControlLogix for many years without knowing it, however, there came a day when dealing with multiple integrated systems, that I needed to use it. I hope it helps you as well.

Are you an experienced controls engineer working in manufacturing or integration with an in depth knowledge of Allen-Bradley and have recently been introduced to Siemens?
Image by Chris Wright
For eleven years I’ve predominately with Allen-Bradley Programmable Controllers, which is not very surprising as they are the most common brand used in North America.
But recently I started working with a manufacturing company who’s equipment is all Siemens, and for the past year I’ve been exclusively working with the Siemens line.
So in today’s article I want to share with you a comparison of these two product lines, including both the programmable controller hardware, as well as programming software.
Controllers:
Let’s start by looking at the Controllers or CPUs of each manufacturer.
From an Allen-Bradley programmer’s perspective, at first glance a Siemens S7-1200 might look like a MicroLogix, with its small form factor and on-board I/O.
Siemens S7-1200 (click for source)
But the S7-1200 is actually more comparable to the CompactLogix in terms of processing power and memory.
That said, the S7-1200 is more limited in add-on modules. It supports a max of 1 signal expansion board (aka plug-in), 8 signal modules, and 3 communications modules, while the latest CompactLogix line, the 5380 series, can support up to 31 I/O modules (with the largest Controllers – Ed.)
Image by Shawn Tierney
On the larger scale Siemens offers the S7-1500, which is comparable to the ControlLogix family of controllers.
The main difference between these two is the S7-1500 does not require a backplane, as it is a din rail mount system.

The S7-1500 also comes standard with two PROFINET ports, which allows the user to separate networks and makes connecting to other devices simpler.
The S7-1500 also comes with a small graphical display which allows for troubleshooting right from the front of the PLC.
Image by Shawn Tierney
One area that I feel Siemens has Allen-Bradley beat in is the remote I/O field.
Siemens offers the ET200 line of remote I/O which can be used as remote I/O or a standalone PLC system as the ET200 can be purchased with a CPU and can be programmed just like the S7-1500; a failsafe CPU can also be purchased.
I use this option quite a bit in smaller machine applications as it is cost-effective.
Software
Now let’s take a look at the Siemens TIA Portal software; v16 of TIA Portal was just recently launched.
The first thing Siemens has going for it is the HMI and PLC can be programmed from the same software package; yes, I know Connected Components Workbench allows for the same but it is not even close to TIA Portal. (TIA Portal comes with WinCC Basic to program Siemens Basic Panels, and can be upgraded to support higher end HMIs. Rockwell’s Studio 5000 Logix Designer comes with View Designer for the PanelView 5000 HMIs – Ed.)
TIA Portal software allows the user to connect to PLC where the IP address is unknown, allowing you to connect to the PLC through the accessible devices option simplifying configuring of a new PLC, and eliminating the need to use a utility like BOOTP.
Image by Chris Wright
Siemens also does not require other software such as RSLinx and FactoryTalk View Studio in order to program and setup the PLC and HMI.
One issue I do have with this is if I make an HMI change, someone cannot come behind and upload the HMI changes I made. I would instead have to give them a copy of my PLC program.
Programming Environment
Now to everyone’s favorite topic: What is the difference between Siemens and Allen-Bradley in the programming environment?
Short answer: a lot, but to cover that in detail would be another article. Here we will look at a few of the most noticeable differences.
One of the positives for Siemens is that it allows the user to add an “Unspecified CPU,” and then add the I/O modules to it.
This allows the programmer to start writing code right away even before the exact CPU has been chosen.
In the project tree of an TIA Portal project we see several folders and icons, and most of these serve the same purpose as the project tree functions in RSLogix 5000.
Devices and networks can be compared to RSLinx, but in my opinion better.
This shows the devices that are connected to your PLC network; HMIs, robot, torque boxes, etc.
Program blocks is where you can add Functions, Function Blocks, and Data Blocks, or in Allen-Bradley terms, Routines.
PLC Tags is comparable to Controller Tags in RSLogix/Studio 5000, and is where your I/O will be located with and other tags you might want to add.
PLC Data Types is (as you probably guessed) for User Defined Data Types.
Conclusion
Siemens has come a long way since the days of STEP 7 Classic and it shows.
While in North America Allen-Bradley is the more popular PLC brand, Siemens is starting to make some headway.
Allen-Bradley PLCs allow the user to expand the system more, but this comes at a higher price point compared to Siemens.
And Siemens all-in-one programming software cuts down on software packages and licensing costs; you still have to buy a license for Siemens programming software.
I also feel Siemens makes it easier to setup new devices, and I really like not having to use RSLinx or BOOTP.
However, coming from 11 years of AB programming, I still feel it’s easier to program A-B from scratch vs. Siemens from scratch.

A few weeks ago, many of us were in the same kind of routine. Whatever the schedule may be, basically we got up on Monday morning and headed to the office to do whatever it is that we do every day.
The division of work life and home life felt much more separate than they feel today. While I have supported systems remotely for years, it has not been normal for me to work from home for many days in a row.
I must also add, that it is not only an adjustment for me, but for my family as well. They are not used to me being at the house during the day, though I did get some quality time with my son teaching him about ControlLogix hardware and software, so he is probably wishing I was back at work.
We all hope and assume this time will pass and things will “get back to normal” as soon as possible. But will they? What is next? And what will change in the coming months?
I don’t pretend to have those answers, but from the experiences I have had, I have made some observations about what I believe will change from a work perspective.
Social distancing will continue
No more hugging at the office guys. Seriously, the risk of how quickly many people can become infected very quickly has come to light and companies will not want to risk shutting down an operation due to too many people being sick at one time.
Community coffee pot gatherings will become a thing of the past. Social distancing will be enforced from the office kitchen to every aspect of life.
I believe the division in control rooms and isolation of employees will continue as well. Control rooms and heavy interaction personally with one another will no longer be allowed.
Phones will not be shared among multiple employees and you won’t shake hands with coworkers when you enter a control room. May as well get used to it.
Work schedules and locations will be divided
While most people will be expected to return to the office when the quarantine is over, the capabilities have now been proven that people can work remotely with equal productivity as the office.
While some things may require an office visit, working remotely has now become a proven reality that it can and does work. I would expect there to be more of a mixed location schedule between the home and the office for many people that have the capability.
Evaluation of remote support capabilities
Those of us working from home more the last few weeks have probably had to evaluate how well we can support our systems with the same level of support as being onsite:
System documentation, drawings and address lists are important to have at your fingertips for troubleshooting remotely in a timely manner
Checklists for remotely checking hardware systems become extremely important so hardware failures do not go unnoticed for long periods of time
System alarming and monitoring of control systems from redundancy, I/O and network failures becomes a necessity.
Conclusion
Hopefully during this challenging time, you have been able to work productively and effectively as well as support your systems remotely.
If there have been gaps in your remote support capabilities, hopefully you have made the necessary adjustments to bridge the gaps.
The social changes are probably not going anywhere for a long time, so we better be prepared.

With so many generations of control equipment on the plant floor, a control engineer can be called to look at many different models of control equipment in the same day.
Each piece of control equipment, even by the same manufacturer, will have great or slight differences of operation and methods of use.
I had been in industry a long time before I ran into a redundant PLC-5 configuration. At the time I was asked to make modifications to the program since I was already familiar with RSLogix 5.
But when I walked up to the redundant chassis, I looked at it for a moment like a cow at a new gate.
After talking with some colleagues, I understood that the PLC-5 in a redundant configuration was not the same as a ControlLogix configuration in that it is mainly only a “hardware” redundancy.
In another words, the processors do not synchronize the program code within them.
In fact, each processor can run a completely different version of PLC code and after a failover, the new lead processor will execute the running code and the system can behave completely different than before the failover.
Because of this, it’s very important to have the same PLC code in each processor.
Any time a change is made to one, you must manually make it in the other processor or download the same program to the backup processor.
In this tutorial, we will go through the steps in copying the program from the primary processor to the backup processor.
Step 1
Make any online changes to the primary processor and save the file. Perform an upload to get the most recent data from the registers.
Step 2
Perform a File>Save As> and add a “Backup” to the end of the file name to differentiate the Redundant Processor Name. This new file will be downloaded to the backup or redundant processor after changing the communication path.
Image by Brandon Cooper
Step 3
Open the redundant/backup file while offline and double-click “controller properties”. Then click on the “Communications” Tab. You will need to change the “Octal Address” from the primary processor address to the redundant/backup processor address. In this scenario, the primary processor is Node 3 (Data Highway) and the backup processor is Node 4 (Data Highway). The backup node will always be set one node higher than the primary.

Changed address to Node 4
Image by Brandon Cooper
Step 4
Download the program to the backup processor. It will ask you to confirm the address ( 4 ) and click “yes” and it will ask you if you want to switch from remote run to remote program. Click “yes”. When the download completes, it will ask you if you want to switch back to remote run. Click “yes”. Save and upload this file and you are done.

Conclusion
There are many opportunities from every vendor to understand to maintain system hardware, communications, software, firmware and system programming. Even after many years, we may not have experience with all of them.
If you run into a scenario and find a PLC-5 running in a redundant scenario, this article will hopefully be of help to you. My best to you in maintaining your legacy control systems.

This week millions of Americans will begin working from home for an extended period of time. For most, it will be the first time they’ve worked from home for such an extended period of time.
For others, the challenge will be trying to remain productive while their spouse, roommate, and/or children are also home from work and school.
With that in mind, today I’m going to share several practical tips I’ve come to learn after I left a long career as a specialist to work at home full-time.
My home office: Everything two people need to work (plus a spare TV and Recliner) crammed into a 10′ by 10′ room
Tip 1) Setup A Place To Work For The Duration
One of the most important things you can do is dedicate a place in your home as your work-space.
It could as simple as commandeering a section of your kitchen table, or setting up a folding table in a bedroom.
Where ever you choose, set it up for the duration with all the comforts of your office desk including things like a power strip, phone charger, pens, and sticky notes.
And if you’re using a laptop, consider investing in an external monitor (or two,) and full size keyboard and mouse.
If you’re worried about sitting all day now that everything’s within arm’s reach, I can highly recommend this transforming work-space which allows you to easily switch between standing and sitting.
Tip 2) Keep To Your Routine
The biggest mistake I’ve seen people make when they begin working from home is they don’t keep to their previous routine.
This often results in their work day starting late, which then leads to having to work through dinner to finish the day’s work.
Instead, try keeping to the same routine you had when you weren’t working from home, heading into your home work-space when you’d typically start your commute.
Tip 3) Batch Your Emails
Another mistake I see many make when they begin working at home is that they start instantly responding to every email as it comes in.
This isn’t something most of us can do at work, and quite frankly it’s counter productive.
Instead, try opening your email client once every hour or two in order to more efficiently address new emails at regular intervals.
Tip 4) Take Breaks Away From Your Work-Space
This may seem counter intuitive, but my personal experience agrees with studies that show taking regular breaks every couple of hours makes you more productive, not less.
So don’t feel like you have to work eight straight hours with only a few minutes off to use the bathroom and stuff some food in your face.
Instead, get up regularly to stretch and unplug, and you’ll likely find (like I did) that you’re more productive for doing so.
My original office was located in a room/studio I built inside of my garage. I quickly found I couldn’t rely on Wifi, and ended up running an Ethernet cable from the house to the garage.
Tip 5) Make Sure You Have A Good Network Connection
You may find that, with so many other people working at home (or on an unexpected break from school,) your wireless router is struggling to keep up.
If so, you may want to run a wired connection from your PC to your router, even if it means laying out a long Ethernet cable each morning.
I’ll include an Amazon link to the Ethernet cables I use here since they work well and come in extra long versions.
Tip 6) Your Own Broadband Connection?
My wife and daughter both work for local school systems, which means that along with my grandkids, they’re home using our internet connection most of the summer.
After trying several different services, routers, and dozens of configurations, I finally found the best results came from getting a second Cable Modem (and the appropriate splitter) from my local Cable Company.
While it may seem counter intuitive, I’ve definitely have a higher speed and more reliable connection now that the family and I each have our own Cable Modem paired with a “Middle of the Road” plan (as opposed to when we all shared a single Cable Modem with a “High-End” plan.)
Tip 7) Quiet, Please
If you’re like me, you think better when you can hear yourself think. But it’s also not reasonable to expect your family to be silent all day long.
To address this, I’ve used several different solutions.
First, if I’m in another room and finding the family’s activities are distracting me, I find I can mitigate the distraction by softly playing some Jazz or Classical music.
And for louder noises, I encourage family members to wear headphones during the work day.
A lot of parents don’t know it, but most video game consoles allow users to plug a standard pair of headphones right into the game controller to eliminate blaring TV speakers.
That’s not only a great way to listen to games, but also works when using a console to watch YouTube, NetFlix, and other streaming services.
And for family members who want to watch Cable or Satellite TV without running a headphone extension cord from the back of the TV, most can view the very same content on their phone, tablet, or PC (with headphones 😉 by using the Cable or Satellite Company’s official app.
If all else fails, before buying a set of expensive “noise canceling” headphones, consider trying 3M’s WorkTunes product.
I originally purchased these to listen to audio books as I mowed our three ache plot each week (as well as snow-blow our three hundred foot driveway after each winter storm.)
But over the years I’ve found it’s also useful to block out my surroundings when I’m trying to concentrate on my work.
Tip 8) Equipment That Really Works
There’s some additional equipment you may want to add to your home office if you’ll be working there for an extended period of time.
These include a quality webcam, microphone, and headset for your phone or PC.
When it comes to webcams, I’ve purchased several but found only the Logitech HD Pro Webcam C920 or C922 work well enough to recommend.
Next, if you’re going to be doing a lot of WebX or GotoMeetings, I’d recommend a high quality headset for your phone, or if you plan to use your PC I’d recommend either a HyperX Cloud wired headset, or a Cosairwireless headset.
I’ve spent hundreds of hours in online conferences in each, and both products are excellent choices.
Finally, if you’re going to be the one presenting during web meetings (or appearing as a guest on podcasts) there’s only one quality USB Mic on the market I’d recommend: The Blue Yeti microphone (I own several.)
Pair it with a good “pop filter” and you’ve never sounded better 😉
Other Tips?
After brainstorming and writing up these tips over the past few hours, I’m now curious to hear what tips you might have to share?
If you’re up to it, please share your tips with us below as either a Forum or Blog comment.

If you’ve been installing or maintaining industrial automation products going back to the twentieth century, then there’s a good chance that you attended one or more in-person classroom training courses.
Yes, it’s true there were other options available back then, including physical books, VHS Video Tapes, and Computer Based Training software. But none of these ever seriously competed for the same market that classroom training had.
Welcome to the Connected Age
Fast forward a few decades and now we live in a world where high speed internet access is widely available, and most of us have multiple “connected” devices within reach 24/7.
Even those of us who are the most conservative about adopting new technology are beginning to see the advantages our connected age has to offer.
At this point in the twenty first century, most of us have already replaced bookcases full of manuals with network folders full of the electronic versions.
Many of us have also put boxes full of CDs and DVDs into storage now that most (if not all) of our media and software is just a few clicks away.
But what about Industrial Automation Training? Can we replace some Classroom Training Courses with Online Courses? And what would be the pros and cons of doing so?
The Cost of Teaching in a Classroom
Comparison of an online course versus a classroom course
Let’s not beat around the bush: Classroom training is expensive anyway you look at it.
To start, the company providing the training has the up-front costs of the curriculum itself, which often has to be created from scratch or significantly customize to fit their needs.
Next, teaching hands-on courses requires purchasing and maintaining several sets of equipment and computers for students to use.
Then there’s the cost of employing an experienced instructor, as well as the cost of either (1) a training facility, or (2) travel, shipping, and rental costs of holding courses in remote locations.
With all those expenses you’ll be hard pressed to find any classroom training that doesn’t cost at least $500 per day, per student.
The Cost of Attending Classroom Training
For many companies it’s not the cost of the training itself that’s the issue. It’s often the time the employee will be out of the facility to attend the training that’s a bigger concern.
After decades of rightsizing and lean manufacturing, most facilities are hard pressed to maintain peek performance when employees go on vacation, never-mind giving them additional time off each year to sit through training.
And if the course isn’t being held locally, travel and lodging expenses can often cost more than the training itself!
Classroom Training Pros and Cons for Students
While classroom training is expensive, there are many times when the advantages of attending classroom training in person far outweigh the costs.
First is the fact that once you’re signed up and committed, you’re almost guaranteed to complete the course.
That’s different from self-paced training options (like Online Training) where it typically requires a monetary incentive or the focus of a group manager to insure employees complete the courses their company enrolls them in.
Second, by being physically present in a classroom you not only get the opportunity for in-person Q & A with the instructor, but you’ll often have the opportunity to get hands-on time with equipment that you might not otherwise have access to.
That said, not everything about classroom training is perfect.
The sad truth is most classroom training courses are designed to progress at pace of the slowest student.
While theoretically this sounds like a good thing, in practice it often means many (if not most) students spend much of the course waiting on slower students to finish their work.
Second, since most industrial automation equipment is relatively expensive, most classrooms assign two students per workstation. This often leads to the students progressing at the pace of the slower student.
Finally, studies show that most students only retain about 30% of what they learned in the classroom, especially if they aren’t able to put it to use right away.
The Advantages of Online Training
Comparing an online course with in-classroom course
When your training budget won’t accommodate the expense of classroom training, or you just can’t afford to have your best people out of the facility for days on end, Online Training can be a very attractive option.
And while enrollment costs for Online Courses varies widely based on the topic, on average per seat costs run between $50 to $500 per student per course.
Those prices are a huge savings over Classroom Training, and typically allow companies to enroll entire groups at a lower cost than sending just a single individual to one in-person course.
But those savings shouldn’t surprise us, since Online Training courses don’t have the expense of a physical classroom filled with PCs loaded with licensed software and connected to expensive hardware.
Additional savings that come from allowing instructors to focus on creating new lessons and courses while students take existing lessons and submit questions electronically.
The Full Cost of Online Training
It should be noted, however, that the total cost of Online Training is often more than the cost of the course itself.
While it’s likely your employees already have a company supplied PC with Software Licenses already installed, not all companies have extra Hardware for employees to use with their online courses.
That’s not to say every student must complete hands-on exercises to learn the course’s content, but studies show that about two thirds of the population learn best by also “doing” what they are learning.
Training equipment costs will vary greatly depending on the topic and equipment the student is learning. It can be as low as $100 to purchase a Small PLC, or as high as $20,000 or more for a high-end “all in one” trainer in a box.
On the upside, once you own the equipment it can be used by multiple employees and is also available if employees want to retake courses in the future.
Online Course Features: What To Look For
If you’re considering online training for your employees, first and foremost you’ll want to look for courses that don’t come with expiration dates or limits on how many times the student can take the course.
The simple fact is, most of us will need to take a refresher from time to time, so being able to jump back into a course and retake lessons as needed is invaluable.
Second, you’ll want a course that comes with more than just lessons. As I alluded to earlier, while some people learn best by watching, many more learn better by actually practicing what they see.
So be sure that the online courses you consider not only include exercises for the student to do (many of which will require the equipment we discussed above) but also include the completed exercise files so students who run into issues have something to compare their work to.
In the case of HMI and SCADA courses, you’ll also want to insure the instructor includes the PLC code for different controllers so it’s more likely the student will have the code for the PLC he’s using with the HMI or SCADA system.
And in the event that a student gets completely lost, make sure the course comes with instructor support.
While instructors may not have the time to support students on topics outside of the courses they teach, they should be available electronically if students have questions on their lessons.
Finally, any online courses you consider for your employees should also include tests or quizzes to insure the student is comprehending the lessons he’s taking.
That and a progress tracker for supervisors and/or group leaders, so they can verify each students progress though the course (or courses) they are enrolled in.
Classroom vs Online Training Summary
Classroom training definitely has its advantages, but in my experience working in industrial automation industry over the last thirty years has shown me that most of those who’d like to attend these courses won’t be able to due to the time and cost required.
If you find yourself in that situation, I highly recommend looking into Online Training Courses like the ones I teach on our sister site, TheAutomationSchool.com.
Until next time, Peace ✌️

If you have had ControlLogix systems running in your facility for any amount of time, chances are they contain ControlNet communication modules for the communication between processor chassis and their controlled remote I/O chassis as well as a myriad of other uses.
Being a deterministic, as well as a stable network, ControlNet was the primary method of communications between ControlLogix processors for produced/consumed tags as well as being the primary method of communications to a remote I/O chassis.
Along with these uses, ControlNet has many other uses including specialty communications such as a 1770-KFC15 where ControlNet to Serial communications are achieved for system integration into legacy systems.
However robust it was, slowly but surely, ControlNet for remote I/O communications is being replaced with EtherNet communication.
Rockwell has incorporated their DLR (Device Level Ring) topology into remote I/O communication networks.
If you are contemplating changing the communication to your remote I/O chassis from ControlNet to EtherNet, this article could be helpful for you.
Getting Started:
Step 1) I recommend making one or more backups of your PLC program
Make two copies of the program to work with. One with name ending in CNET and one ending in ENET for clarity.
Step 2) Open the programs side by side on your programming terminal
Image by Brandon Cooper
Note: It is very important to make note of the names of your CNET Modules. You must rename the new ENET Modules with the same name for tag alias and names to converge when completed.
Image by Brandon Cooper
Step 3) Both Copies of the program are open, so you are ready to begin. Start by deleting all the I/O Modules and ControlNet Modules in the Project that ends with ENET.ACD
Image by Brandon Cooper
Below all ControlNet Modules and remote I/O Modules are now deleted.
Image by Brandon Cooper
Step 4) Begin adding an EtherNet Module in the local chassis and one for each remote chassis. This is where it is very important to name the EtherNet Modules with the same name that the ControlNet Modules had.
Image by Brandon Cooper
Step 5) Drag and Drop each I/O Module from the project ending in CNET to the project ending in ENET in the correct chassis.
Image by Brandon Cooper
You now have all EtherNet communications modules in your remote I/O chassis
Image by Brandon Cooper
Step 6) Run the “Verify Controller” command to ensure the I/O assignments, tag aliases and all other information is correct.
Image by Brandon Cooper
For more on this topic, see Rockwell’s Tech Note 1092818 (or Publication CNET-RM001 – ed.)
Conclusion:
As you begin upgrading existing ControlLogix systems that contain ControlNet communication modules to EtherNet communication modules for remote I/O, preparation and attention to detail will be the factors for success.
Make plenty of backups, note the module names and stick to the procedure. Be sure to reference the Tech Note listed above for additional information.
This entire procedure can be completed and your system can be cut over to EtherNet communication in less than a half hour.
My best to you in your control system upgrades.

A deep understanding numeral systems like binary, octal, and hex is something that most of us who program industrial automation products have in common.
And for the first T-Shirt in our “Data” series, I started with one focused on Binary.
While most bystanders will just see the number Ten, our fellow bit heads will need no explanation why that would equal to “The Power Of Two”:
These T-Shirts come in two logo types: One shows two binary digits (10) while the other shows four (0010.)
They also come in multiple colors (not just black and white 😉, and in one of two different prints:
– Large Front Logo ($18)
– Small Front Logo and Large Rear Logo ($24)
If you’d like to find out more about these new shirts, check them out in our shop here.
And if you have any thoughts or suggestions, please let me know them as a reply to this post 🙂
Until next time, Peace ✌️

Have you ever used or thought of using your HMI as a network monitoring tool?
What if your HMI system was used for more than just an operational tool? What if it can also help you, as a control system engineer, with system documentation, network troubleshooting and much more?

I have found great benefit in the integrated nature of modern control systems. Rockwell has built on the Cisco operating system within their Stratix model switches.
While the Stratix switch configures the same as any other Cisco switch, its integration capabilities make it a nice choice to use in a ControlLogix configuration.
I have found many instances in which I was able to obtain needed documentation or troubleshoot a network issue in seconds without ever having to open an SSH session or drag a laptop with a console cable to a network switch to connect to it.
Preparing your Stratix Switch for integration to ControlLogix:
1) Run the global command: “macro global trace ab-global $cip_vlan 1” in your stratix switch. (NOTE: Substitute vlan 1 for the actual vlan your switch is configured for)
2) Run the following commands: “service-policy input CIP-PTP-Traffic” and “alarm profile ab-alarm” on each Switch Port that you will get CIP traffic from.
4) First, you will need to download the needed AOP (Add-On Profile) from Rockwell for your Logix Designer system. Reference Tech Note: 504868 for more information on downloading the 1783EtherNet Switch AOP.
5) After downloading and installing the needed AOP files, you will need to reboot your PC. You should now be able to add a Stratix switch into your Logix Designer Project.
6) In the logix Designer application, In the I/O Tree, right-click and select “New Module” and follow the prompts to add the correct model of Stratix Switch that you are using.

7) After creating the module, view the module defined tags in your controller tag database:

You will now be able to monitor important switch information via your HMI system.
The following is a simple illustration, but with a little imagination, this can get as informative and valuable as you envision it to be:

Conclusion:
If you are looking to create dynamic data, documentation and troubleshooting tools in your control system, a great way to start is by using the integration tools that are available to you.
Though these tools are known, they are often overlooked and left without implementation. Go that extra step and make troubleshooting simple when you need it down the road.
The only limit to this kind of opportunity is our imaginations.

If you are contemplating using a Device Level Ring (DLR) topology in your control system networks, an important device in that network is the EtherNet Tap (ETAP).
If the remote devices in your DLR network will require fiber, the ETAP device will work as a media converter changing your communication media back and forth from multimode fiberoptic to RJ45.

Keep in mind, you may use a Stratix switch to accomplish the same thing, but the cost will be significantly more. The 1783-ETAPxx is also configurable to be a ring supervisor or backup supervisor for the network.
In the following instructions, I will take you through the simple setup of setting the IP address of a 1756-ETAP1F through RSLinx.
Prerequisites:
Apply 24 VDC to the ETAP device
Set the IP address of your laptop to 168.254.1.(Anything other than .1 as this is the default address of the ETAP device)
Connect your laptop ethernet cable to the front (device) port of the ETAP
Image by Brandon Cooper
Getting Started with Configuration:
Open RSLinx and browse with the EtherNet IP Driver (RSWho)
Image by Brandon Cooper
Right-Click on the ETAP device and select “Module Configuration”
Image by Brandon Cooper
Select the “Port Configuration” tab
Image by Brandon Cooper
Change the IP Address and Subnet mask to the network scheme of your DLR network
Image by Brandon Cooper
Click “Apply”, and when asked “Do you wish to continue?”, select “Yes”
Image by Brandon Cooper
You will now need to change your laptop IP address to the same IP scheme as the new ETAP device IP Address if you wish to reconnect to the ETAP device.
Other considerations:
If you are ordering 1783-ETAPxx devices, don’t forget the 24VDC power supplies!
I recommend having separate power supplies for each ETAP device
The 1783-ETAPxx device uses LC Multimode Fiber connectors, so you will need fiber patch cables with LC connections.
Single Mode Fiber is not supported.
In RSLinx, you can also configure the Ring Supervisor or Backup Ring Supervisor mode for the ETAP device and it can be messaged for diagnostic information in your Logix processor code.
Reference: Publication “1783-IN018A-EN-P” from Rockwell Automation for further instructions and information on the 1783-ETAPxx device
Conclusion:
This easy to configure device can be set up in less than five minutes and is a good option for media changes in your control system network.
As previously stated, you may use the Stratix switches for a DLR network and they are the best option in some cases, but for a simple configuration with one or only a couple of remote chassis, this is the most cost-effective option.
My best to you in developing your DLR network.
