PlantPAx Process Objects – What are they?

PlantPax fi


PlantPAx booth at Automation Fair 2013I’ve been getting a lot of questions about PlantPAx lately. Specifically about PlantPAx as it pertains to HMI and SCADA systems.

While PlantPAx is a very wide and broad topic, when I get the above question it typically relates to Rockwell’s highly developed faceplates, formerly known as the “PlantPAx Library of Process Objects.”

The purpose of these “objects” or “faceplates” is to provide a modern interface to Rockwell HMI and SCADA products along with the ease and functionality of legacy DCS systems.

Faceplates

FTViewStudio Global Objects 2From the operator’s perspective, the PlantPAx Process Objects appear as a popup window that is displayed when he clicks on certain parts of his HMI or SCADA user interface.

These “parts” typically represent motors, valves, or other such object which is being controlled by the automation system.

These faceplates include everything from status of the current device, to alarming information, to scaling and bypass capabilities, assuming the user has the rights to access these settings.

In most installations, security will be implemented to require a users to log in before any control or configuration features of the faceplates can be accessed.

Parts and Pieces

PlantPAx Process ObjectsYou wouldn’t know it by using them, but the PlantPAx Process Objects are more than just popup displays. Each one consists multiple parts, including:

  • Main “on top” display populated with global objects
  • Global objects used for multiple displays
  • Graphic images for buttons and various parts of the global objects
  • HMI tags (for use with Rockwell’s ViewME version of the displays)

How to get PlantPAx Process Objects

UPDATE: For the new 2017 procedure to download PlantPAx Process Objects for free, click HERE.

While the PlantPAx Library of Process Objects are provided by Rockwell at no charge, since they are only distributed through Rockwell’s Knowledgebase via a “locked” document you’re required to PlantPax Library of Process Objects Knowledgebase Documenthave a current Rockwell support agreement (aka Tech Connect) to access them.

If you do have “Tech Connect” level access you can get the latest copy of the Process Objects HERE (62682.)

EDIT: While the PlantPAx Library of Process Objects still requires a Tech Connect support contract to download, the Tech Note listed above is now viewable by the public, along with a summary document which can be downloaded.


I hope you found the above article explaining the PlantPAx Library Process Objects helpful. If you have any comments, questions, or corrections please don’t hesitate to leave them with us by submitting the “post a comment or question” link below.

Small Allen-Bradley (A-B) Ethernet Programmable Controllers

Small Ethernet PLC's from A-B



Small Ethernet PLC's from A-BToday, Ethernet is the network of choice for automation systems.

In years past, Ethernet was an expensive and costly add-on. However, more and more small programmable controllers are now coming with Ethernet as standard.

Below we’ll cover what is available today for small Ethernet Programmable Controllers from Allen-Bradley.


Micro820 and 850

IAB Micro820If you’re new to programmable controllers, or just new to Allen-Bradley, the Micro800 family is a pretty good choice.

Programming Micro800’s with the free CCW software feels more like programming other vendor’s PLCs than previous A-B PLC’s. This fact is a plus for those who have used other PLC’s, but it’s a minus to those who are familiar with the RSLogix interface.

The Micro820 is the newest and smallest of the Micro800 family to have Ethernet. This small 20 I/O PLC starts at $249 list, which is a very attractive price point. For more about the Micro820, check out our previous blog posts about it HERE and HERE, and our podcast about it HERE.

IAB Micro850The Micro850 is the largest and most expandable PLC in the Micro800 line. It comes in two I/O sizes, 24 and 48. The 24 point I/O model starts at a list price of $429, while the 48 point model starts at $629 list.


MicroLogix 1100 and 1400

IAB MicroLogix 1100If you’re an existing user of the PLC-5 or SLC-500, then you’re going to feel right at home programming a MicroLogix. In fact, unless your RSLogix 500software is ancient, it supports the entire MicroLogix line out of the box. You can also buy a “MicroLogix only” version of RSLogix for $150 which will program all the MicroLogix PLCs.

The MicroLogix 1100 was the first MicroLogix to include Ethernet, as well as a small LCD display. It was also the first MicroLogix to support online editing too, a huge advancement for the MicroLogix line. However, this MicroLogix only comes in 16 I/O versions, and starts at $648 list.

IAB MicroLogix 1400The MicroLogix 1400 is the newest MicroLogix, and is loaded with extra features. In additional to all the feature of the 1100, it also has a backlit LCD, the ability to set the IP address from the front of the unit, and supports Modus TCP as well as Ethernet/IP. The MicroLogix 1400 has 32 total I/O (some models also include additional analog I/O) and starts at a list price of $855.


CompactLogix 5370

IAB CompactLogix L1The new line of CompactLogix 5370 processors are a very good choice for newer plants which have standardized on RSLogix 5000.

While the CompactLogix hardware has less features than the larger ControlLogix, it does support all the same programming languages and instructions.

The “L1” processor has 16 I/O built-in, and can be expanded with a few 1734 Point I/O modules locally. It also has the ability to control a few racks of remote Ethernet/IP I/O, and starts at a list price of $1,460.

IAB CompactLogix L2The “L2” processor also has 16 I/O built-in, but it takes 1769 Compact I/O expansion modules locally. It has the ability to control several racks of remote Ethernet/IP I/O, and starts at a list price of $1,900.


A word about list prices.

While Rockwell authorized resellers are free to set their own sale prices, some precedence’s do exist. For one, as the list prices mentioned above can be found on Rockwell’s own website, most distributors won’t quote you prices above list.

Note: You can also find the above prices and all the pictures in this article in Rockwell’s free, “Integrated Architecture Builder” (IAB) tool. For more information about IAB, see our blog articles HERE and HERE.

If a Rockwell distributor does quote you a price above list, they should expect the same reaction you would have if your local department store tried to charge you more than the price found on a product’s label. For most, this would mean leaving the product behind and finding a new store.

Flashback Friday! RSView32 Tour

Flashback Friday RSView32 Tour Fi

Flashback Friday RSView32 Tour FiWelcome to The Automation Blog’s very first, “Flashback Friday!”

This blog series highlights automation articles and content that I originally posted on my previous website(s) between 1999 to 2013.

Today I’m highlighting my first automation post from way back in 1999: RSView32 Tour.

RSView32 TourIn June of 1999, I was working as a full time HMI and SCADA software specialist in my home state of Rhode Island. In those days I spent most of working hours showing clients the ins and outs of RSView32, Rockwell Software’s flagship SCADA product.

After sitting through a colleagues presentation of the function and features of RSVie32, I came up with the idea to make a demo project that would show off examples each and every feature. My “RSView32 Tour” project was the result.

To read the original story and download the project, see the reposted article here on The Automation Blog:

How to set the Ethernet/IP address of your new CompactLogix using the USB port

1769-L3, L2, L1 CompactLogix


1769-L3, L2, L1If you’re still using BOOT-P to set the IP address of your USB equipped 5370 CompactLogix, today I’ll show you a much easier way.

First, you’ll need a standard USB cable. This is the same type you would use with a USB printer with the familiar flat side which plugs into your PC, the nearly square side which plugs into your 5370 CompactLogix.

RSLinx USB Driver - RSWho finds L24Once you’ve connected you PC to your 5370 CompactLogix using USB, and have powered your CompactLogix on, you will see Windows load the drivers, and then a new USB driver appear in RSLinx automatically.

Note: To use the USB driver in RSLinx Classic you’ll need to have a fairly recent version (no, the 1996 version will not work.) You can get the latest version of RSLinc Classic Lite for free from Rockwell HERE.

RSLinx USB Driver - Right Click on L24 to ConfigureWhen you expand the USB driver in the RSLinx – RSWho, you’ll see your CompactLogix. At this point just right click on it, select Module Configuration, and the Port Configuration tab and you can now change the Ethernet port’s IP address.

Tip: This procedure also works with the new 5570 1756-L7x processors, as well as USB 1756 Ethernet modules like the 1756-EN2T.

RSLinx USB Driver - L24 IP ConfigurationI hope this article on how to change an IP address by going through the USB port is helpful. If you have any comments, questions, or corrections please don’t hesitate to leave them by using the “post a comment or question” link below.

RSLogix 5000 Previous Versions DVD Returns

Studio 5000 Disc 2


UPDATE 11/10/2017: Most of Rockwell’s existing software product part numbers which end in “ENE” will no longer provide you with a “physical shipment” of software. So to receive the DVD set as shown in this article, you need to replace the “ENE” in the part number with “ENM”

Studio 5000 Disc 2 Featured ImageIt’s been a long several months. Ever since Rockwell decided to remove the “previous versions” DVD from new orders of RSLogix 5000, aka Studio 5000, confused and upset clients have been calling in.

Why this second DVD was removed from the software package in the first place is still a mystery to me (for details of what’s in the box see this blog post.) Rockwell sells software which costs much less than RSLogix 5000, and in those packages you get up to four DVD’s (see an example of this here.)

Studio 5000 Disc 1As one client put it, “I convinced my company to spend over $3000 and I can’t even program my ControlLogix L61?” Even worse, customers wanting to buy the “right” version to program their existing controllers had no options. When Rockwell released version 21 and rebranded RSLogix 5000 as Studio 5000, all the software part numbers remained the same.

It just seems counter intuitive to even consider not shipping the “previous versions” DVD in the box with version 21. Only a tiny fraction of Rockwell’s Logix customers actually have a  new 5570 or 5370 processor which is all v21 supports. And of those customers, only a small fraction has adopted v21 opting instead to stay with version 20 which supports a much wider range of controllers.

Studio 5000 Disc 2But this is all now “water under the bridge” as in the last couple of weeks new orders for RSLogix 5000, aka Studio 5000, have again started coming with a “previous versions” DVD.

Now if we could just get some sort of bright “read this first” flyer informing customers they only need to install the actual version that matches their controller, the confusion level for new customers could be greatly reduced.

I hope the above article about RSLogix 5000 was helpful. If you have any questions, comments, corrections, or suggestions please don’t hesitate to share them with us by using the “post a comment or question” link below.

How to avoid “bricking” Point I/O modules when you attempt to flash firmware

Failed to flash 1734-OE4C step featured image


Failed to flash 1734-OE4C step 1I was recently contacted about some very experienced controls engineers who had ran into a strange issue. They had come across a firmware problem with one of Rockwell’s 1734 Point I/O modules, but weren’t having any luck successfully upgrading the firmware.

Actually, it was worse than that sounds. The bug the had been found in the middle of a very tight start-up schedule. And when the manufacturer found the bug six months earlier, it had not sent out proactive notices to the owners of the products.

The next day I visited the site to see if I could help. When I arrived and booted up my laptop, I started by launching Windows task manager and ending any processes and programs that I wouldn’t need running to flash firmware. Then I deleted all my RSLinx drivers and only added back in the one driver I would be using.

Failed to flash 1734-OE4C step 2Next I opened an RSWho window and browsed the 1734-AENT’s backplane to be sure RSLinx could see the I/O modules. Then I launched ControlFlash, crossed my fingers, and attempted to flash the first of several dozen 1734-OE4C modules.

Even with a quarter century of experience using PLC’s, I still got a little nervous as I watched the progress bar. The engineers that I had come to help had told me the firmware flash never got much past 10%.

Flashing of the first module was successful, but it was also a little bittersweet. While it did mean that the startup of Point I/O racks could continue, it didn’t explain why several of the engineering firm’s PC’s had failed to flash the same type of module?

I went ahead and flashed nearly a dozen modules before they were taken out to the field to be swapped out. As I waited more modules to flash, I thought it might be worth calling Rockwell’s Tech Support to see if there was an undocumented way of re-flashing the modules that had been bricked.

Failed to flash 1734-OE4C step 3While on the phone with Tech Support, I became a little distracted. After giving up on the failed units, I attempted to flash another new module, but surprisingly it failed. Stunned, I just sat their asking myself what I’d done differently? Why was my laptop now unable to flash these Point I/O modules? What had I missed?

I cycled power to everything and attempted to flash another module and had success, but then the next two I attempted failed. I began running through the procedure with one of the firm’s engineers when it hit me. In my attempts to reflash the old modules, and distracted while talking on the phone with Tech Support, I had stopped closing the RSWho window which was browsing the Point I/O backplane.

Now, I typically leave the RSWho windows in RSLinx open and browsing, as I often “alt-tab” back and forth between RSLinx and RSLogix. However, when I had initially began flashing the Point I/O modules earlier that morning, I had closed the RSWho just to be sure I had as few programs using the network as possible.

Failed to flash 1734-OE4C step 4Later, when I had gotten sloppy and left the RSWho window open and browsing the backplane, that small amount of additional network traffic had caused the failure of ControlFlash to successfully upgrade the firmware of the 1734-OE4C.

To confirm this was indeed the issue, we connected up one of the engineering firm’s PCs which had previously always failed to flash these modules. Then we attempted to flash several 1734-OE4C module, but this time with the RSWho window closed, and they were all flashed successfully.

So word of advice to anyone using Point I/O: If you plan to flash any of your Point I/O module’s firmware, play it safe and make sure you’ve closed the RSWho window inside of RSLink classic. Otherwise, you may find leaving it open will result in your module becoming a useless “brick.”

I hope this article about flashing Point I/O modules was helpful. If you have any comments, questions, or corrections please don’t hesitate to share them with us by using the “post a comment or question” link below.

1734-OE4C Analog Output Module Not Holding Last State

1734-RN014 FI


1734-RN014I recently became aware of an issue with the 1734-OE4C not holding late state. If you use this module in an installation in which holding last state is important, you’ll want to read the following.

As I described in Monday’s blog, there are some control systems which rely on outputs holding last state in the event they are no longer under control. These events could be as simple as s network cable being disconnected, to a programming error resulting in a controller fault.

While no major control system I know of lacks this feature, in November 2013 Rockwell published a “Release Note” document describing a firmware bug discovered on the 1734-OE4C. This bug prevented the 1734-OE4C from correctly implementing it’s “hold last state” feature.

Point-IO verticalHonestly, I’m surprised this information was put forward in a “Release Note” instead of one of their “Product Notices.” Announcing a bug in “Release Notes” alone seems to me to be reserved for the most minor bug fixes. And the inability for an output module to “hold last state” frankly seems more serious than that.

Note: You can read Rockwell’s 1734-OE4C release notes using this LINK.

Not a compete fix?

While the new 3.003 firmware does fix most of the hold last state issues, surprisingly one still remains. Today, even with the new 3.003 firmware, if you preform a download to your controller the 1734-OE4C module still will not hold last state. This is quite unlike how Flex I/O and 1756 I/O operates.

As confirmation of this remaining issue has been sent to Rockwell, it’s my hope that we will soon see updated firmware allowing all Point I/O modules to “hold last state” under all conditions. Until that time, if holding last state during a controller download is important to you, you may wish to use another I/O platform until the Point I/O line is patched.

I hope the above article on the 1734-OE4C not holding last state is helpful. If you have any comments, questions, or corrections please don’t hesitate to share them with us by using the “post a comment or question” link below.

Why the option to “hold last state” is important in control systems

Compact IO Featured Image


CompactLogix panelThere are some control system applications where system outputs must hold last state in the event they become physically disconnected from the controller, or if the controller stops controlling those outputs for any reason.

These applications include some heating, cooling, and pumping applications where the safest failure state is for the outputs to continue in their last state as opposed to turning off when control has been lost. Examples include:

  • A material may need to stay heated to keep it from solidifying and clogging up tanks and pipes.
  • A freezer may need to be kept on to ensure it’s contents don’t spoil.
  • An exhaust fan may need to continue to run to insure unsafe levels of gases don’t build up.

Reasons why control systems outputs could become disconnected from their controller vary greatly. They include everything from a technician accidentally disconnecting the wrong cable, to construction workers inadvertently damaging network conduits.

1756 Redundant ProcessorsIn additional to human mistakes, actual hardware failures are also a possibility. One of the weakest links is the power system. Everything from a power outage, to a power supply component failure, could result in the controller going offline. And though rare, occasionally controllers do also fail.

Aside from becoming disconnected, there are other situations in which a control system can loose control of it’s outputs. For instance, a control program may contain a bug which causes the processor to fault. Or, a new control program may need to be downloaded to the controller, temporality taking it offline.

That’s not to say there aren’t means to avoid these scenarios. Uninterruptible Power Supplies (UPS) and redundant power supplies can be used to insure Controllers receive continuous 1756 Redundant Power Suppliespower. And redundant controllers can be used to insure a controller failure doesn’t take down a system.

Fault routines can be used to insure programming errors are captured and addressed. And most of today’s control systems allow for editing or importing code while the control system continues to run.

But even using the above precautions, in many applications the danger of control system outputs not remaining in last state is so great there is just no good reason for any control system manufacturer to release output modules in which this feature is not rock solid.

I hope the above article on the importance of control system output having the capability to hold last state was helpful. If you have your own thoughts you would like to add to the conversation, please feel free to click on the “post a comment or question” link below.

Seven things you should know about Studio 5000 Logix Designer v21 (formerly RSLogix 5000)

Studio 5000 Logix Designer Splash FI

It’s been just over a year since Rockwell launched Studio 5000 Logix Designer, and it seems I’m getting more questions about it now than ever before.

Studio 5000 Logix Designer

As of version 21, Studio 5000 Logix Designer is the new name for RSLogix 5000. However, there are some changes above and beyond the product name you should be aware of before upgrading, and I list my top seven below:


1) Studio 5000 Logix Designer v21 and greater only support “multi-core” Logix controllers

If you plan to use Studio 5000 Logix Designer v21 or greater, your choice of processors is limited to the latest of the latest. This includes the 5570 and 5580 series represent by the 1756-L7x and L8x ControlLogix processors. It also include the 5370 and 5580 series of CompactLogix processors consisting of the 1769-L1xER, 1769-L2xER, 1769-L3xER, and 5069.

Note: Not all new controllers support all versions back to v21.


2) Studio 5000 Logix Designer v21 only supports Windows 7

Still running Windows XP? Well, unless you have Windows 7 (or Windows Server 2008 R2) you won’t be running Studio 5000 Logix Designer v21.

Note: Most of the latest versions only support Windows 10. To find out more, look up the Studio 5000 release notes here.


3) Studio 5000 Logix Designer v21 comes in two incompatible versions

Studio 5000 System RequirementsFinally understand the difference between version 20.01 and 20.03? Time for a redux: Version 21 (or more specifically 21.00.03) of Studio 5000 Logix Designer has the same security holes as v20.01, and Rockwell has released a “patched” version 21.03 has the same backward incompatibility issues that 20.03 has.


4) Studio 5000 Logix Designer Redundancy Support

Studio 5000 21.03If you’re new to ControlLogix redundancy here’s a tip: Not every version of RSLogix 5000 or Studio 5000 supports redundancy (even though the check box to enable it is found in every version.) So if you’re looking for the latest Logix redundancy version, check out the RSLogix /Studio 5000 release notes here.


5) Studio 5000 downloads all comments to the controller

Of all the new features in v21, this is the only one I remember. Since all the new multi-core Logix processors include an additional on-board memory chip, with v21 they also now all support saving routine comments and descriptions into the processor itself.


6) Studio 5000 Logix Designer no longer comes with previous versions, but still has the same part number as RSLoix 5000

UPDATE 08/2022: If you need versions prior to 20.05, you now need to purchase the Legacy option with Studio 5000. See Rockwell’s online software catalog here (you must be logged in with free account to see prices.)

UPDATE 2017: Rockwell changed all existing Studio 5000 part numbers ending in “ENE” to be digital downloads only. To get a physical disk set you must order the part number ending in “ENM”

UPDATE 2014: A few weeks after this article had been written, and several months after the Previous Versions disc had been removed, Rockwell thankfully started including it once more. You can read the full article here:

So you just got in a new piece of equipment with a 1769-L35E? Well, currently there is no software package you can buy that will include a compatible version of RSLogix 5000. However, you probably won’t find out until after you spend hundreds (if not thousands) of dollars on a new copy of Studio 5000.

While my colleagues and I continue to lobby Rockwell to correct what we see as a huge oversight, if you find yourself in this situation don’t hesitate to call whoever sold you Studio 5000 and ask them to burn you a copy of the RSLogix 5000 previous versions dvd.


7) In the future Studio 5000 will include a “View” Designer

So what was the whole point of renaming and rereleasing RSLogix 5000 as Studio 5000 Logix Designer? Certainly not just to enable the saving of comments into multi-core processors right?

As part of a master plan to add more features into a common design platform, behind the scenes a small group of Rockwell’s best and brightest are working on a new editor for a new HMI line. And this new editor, when released, is to be a free addition to Studio 5000.


I hope the above article detailing seven thing you should know about v21 was helpful. If you have any thoughts on this topic yourself please don’t hesitate to share them by using the “post a comment or question” link below.

Rockwell Automation TechED 101

RSTechED Guest Speaker

Update: In March of 2015 Rockwell renamed “RSTechED” to “Rockwell Automation TechED.” To find out more click HERE.

RSTechED Guest SpeakerRockwell Automation TechED:

What is it, How Much is it, When and Where is it, and What Should I Expect?

What is TechED?

Rockwell describes TechED as follows:

Designed for end users, system integrators, distributors, partners, machine builders, TechED gives you the chance to work with the latest Rockwell Automation products and technology solutions in a classroom environment.

In my words, TechED is all about training as there is no trade show component like Automation Fair. When you register for TechED, you build your week’s training schedule by choosing from over a hundred labs, presentations, and technical sessions. This ability to choose only sessions of interest makes it a good choice for electrical and controls engineers looking for training with multiple Rockwell products.

How Much is it and who attends?

Unlike Rockwell’s other premier event, Automation Fair, TechED is not free.

RSTechED HotelIn homage to it’s beginnings as a week long training session solely for Distributor Software Specialists, Rockwell continues to encourage it’s authorized distributors to send their own technical people to the event.

However, over the last decade the focus of the event has expanded greatly. Initially, Rockwell opened registration to select OEM and SI partners. And they continue to encourage these partners to attend TechED by including either half or full price tuition in many of their partner Toolkits.

RSTechED General SessionMore recently, Rockwell has opened the event to all customers, with an “early bird” tuition cost of $1200. Once the “early bird” registration ends, typically a few weeks before the event, the tuition cost rises to $1500.

In addition to the tuition cost, you’ll also need to cover your own lodging and travel expenses. Rockwell does secure a group rate at the event hotel, with a nice room usually running around $180 per night. Add in the cost of flights, transportation, and meals not covered by the tuition, and it’s easy for the non-tuition costs of TechED to close in on the $2000 mark.

What does the tuition price include?

For the price of admission, attendees can participate in as many educational sessions as they can fit into their schedule over the four and a half day event.

RSTechED EDFest with friendsAttendees also receive admission to a Sunday Night reception with complimentary cocktails and appetizers, as well as the Tuesday Night EDFest which typically includes dinner, drinks, and some form of entertainment. These events are both heavily attended and are great times to network with other attendees.

Besides Sunday and Tuesday evening, attendees are also treating to a free buffet breakfast and lunch, both of which seem to get better each year. There is also a Tuesday morning “guest motivational speaker” general session you won’t want to miss.

When and where is TechED held?

TechED is held in mid June each year. Rockwell alternates the event between the East and West with TechED 2013 being held in San Diego, while TechED 2014 is being held in Orlando from June 15th – 2oth

What should I expect?

RSTechED SessionRockwell’s TechED is first and four-most about training. As such, I highly recommend signing up as early as you can so you can reserve your spot in the classes you most want to attend. In the years that I have signed up late, I’ve always missed out on the very popular “What’s new and coming” sessions.

I also recommend getting in early enough to pick up your welcome pack Sunday Night prior to the reception. The welcome packet not only includes your event badge (which you need to get into the reception) but it also typically includes a program guide, a DVD or memory stick, a Polo Shirt, and a copy of your session schedule. Not having to scramble in the morning to pickup your badge and other items makes it much easier to enjoy the buffet breakfast and find a good seat for the opening general session.

RSTechED General SessionOnce training begins, I recommend getting to any hands-on lab sessions as early as you can. While you can’t typically get into a session more than ten minutes early, a line typically forms prior to that outside of the session room. In software sessions where everyone gets their own PC this not such a big issue. But, with some hardware intensive sessions you’ll be pairing up, so the earlier you get in the more choice you’ll have in choosing a lab station.

Finally, if you find yourself in a session which isn’t quite what you expected, don’t fret. Rockwell has session kiosks located near most session rooms so you can quickly duck out of one session and look up what other sessions are currently available during the same time period. This ability to edit your session schedule during the show is very handy and much appreciated.

For a complete listing of this this year’s TechED sessions, click HERE.

Final thoughts

RSTechED Sunday Night Reception with friendsRockwell’s TechED annual week of training is one week I try never to miss. The ability to create my own training schedule from over 100 sessions insures I only sit through sessions which directly apply to me.

That, and the opportunity to network with peers and colleagues both old and new, makes TechED one of the most interesting weeks of the year.

I hope this TechED 101 was helpful. If you have any questions or comments please feel free to leave them here by using the “post a comment or question” link below.

MicroLogix 1500 Expansion I/O

ML1500-XIO-MODULE


ML1500-XIO-END-CAP-2The MicroLogix 1500’s base I/O can be expanded using the popular line of 1769 expansion I/O, also known as Compact I/O. In this article we’ll describe the details of how this is accomplished.

The right side of the MicroLogix 1500 I/O base is equipped with a 1769 expansion I/O port. Out of the box this port is covered with a protective ESD sticker. So, the first step in adding 1769 I/O to a MicroLogix 1500 base is to power down the unit and remove this sticker.

ML1500-XIO-MODULENext, with power still off, slide your first 1769 expansion I/O modules onto the MicroLogix 1500 base using the tongue-and-grove system. Once the module has been completely slid on and lined up with the base, slide the bus connector lever arm (found on the top of the module) to the left until you feel it “click” into place.

NOTE: Most 1769 module issues I’ve seen in the field are a result of the bus connector lever arm not being completely engaged. Always physically inspect the bus connector arm to insure you have indeed fully engaged it.

Now add any additional 1769 expansion modules in the same way as the first. Do this until you have installed all your modules, or until you’ve reached the ML1500-IN-MODULE-Lpower supply limit of your MicroLogix 1500 base. At this point you must either install an end cap (1769-ECR,) or an expansion I/O cable which leads to a second bank of 1769 I/O with it’s own power supply and end cap.

NOTE: Every 1769 Compact I/O system must be terminated with either a right (1769-ECR) or left (1769-ECL) end cap. Without an end cap installed, your processor will fault on transitioning from program to run mode.

ML1500-IN-MOD-ARM-2The total number of expansion I/O modules a MicroLogix 1500 can support is 16. Of those, up to 8 can be installed directly to the base. However, the number of modules that can be connected to the base may actually be less than 8, depending on the power consumption of the chosen modules.

To aid in the process of calculating exactly how many modules can be added, Rockwell has developed an easy to use spreadsheet to help qualify MicroLogix 1500 systems. This spreadsheet can be downloaded from Rockwell’s website using the below link:

It is also important to note that some 1769 modules must be located within a certain number of slots from the base or expansion power supply. So keep in ML1500-XIO-END-CAPmind that you must review each modules power supply distance rating when designing your system to insure you place all modules within their rated distance.

Finally, for those systems larger systems where just adding 1769 I/O to the MicroLogix 1500 base won’t suffice, as mentioned above additional modules can be added in a second bank of 1769 I/O. This additional bank is connected via a cable with two end caps preinstalled, and the second bank it attaches to must contain it’s own 1769 power supply as well as a bus terminating end cap.

ML1500-XIO-END-CAP-2One version of the expansion I/O cable has two right end caps attached, and is typically used in installations where the second bank of I/O will be mounted directly under (or over) the MicroLogix 1500 base. In these installations, the left side of the second bank must have a left end cap (1769-ECL) to terminate the 1769 bus.

A second version of the expansion I/O cable has one right end cap and one left end cap attached. This allows for side by side installations of the base and second bank of I/O. In these installations, the second bank of I/O must be terminated with a right end cap (1769-ECR.)

Well, that’s it for today’s article reviewing the expansion I/O used with the MicroLogix 1500 programmable controller. For more information on the installation of MicroLogix 1500 expansion I/O, see the manufacturer’s installation instructions HERE.

MicroLogix 1500 Installation and Mounting


ML1500-TBAs seen on The Automation Minute earlier this week, the MicroLogix 1500 comes with an extensive installation document. That document is also available electronically on the manufacturer’s website HERE.

While these “installation instructions” cover many different topics, in this blog article I’ll be focusing on the installation and mounting of the controller.

To allow for installation in the widest temperature range possible, the MicroLogix 1500 programmable controller is vented on the top, bottom, and left side. This venting is for convection cooling of the internal circuits of the controller. In order to allow sufficient air to flow through the vents, you need to allow for two inches of spacing all around the unit.

The MicroLogix 1500 should only be mounted horizontally. And when mounting a MicroLogix 1500 controller, it is very important not to allow any debris ML1500-TOPto fall inside the unit’s vents. Metal filings or wire strands which fall into the MicroLogix can damage or destroy it’s internal circuits.

To aid in avoiding such occurrences, the MicroLogix 1500 comes with two protective debris strips installed on the top of the unit. These strips should not be removed until after the MicroLogix 1500 is installed and all wiring and drilling above the unit is completed.

However, the MicroLogix should also not be powered on while these protective strips are installed. If this caution is not followed, the controller’s circuits could overheat and become permanently damaged.

ML1500-BACKWhile most installations will find the MicroLogix 1500 mounted to a din rail, four mountings holes are also provided for surface mounting. When used, the mounting holes are typically utilized to mount the Micro directly to the backpanel of an electrical enclosure. To aid in these surface mounting installations, the product’s Installation Instructions includes a “mounting template” to help in spacing mounting holes accurately.

Well, that’s it for today’s article reviewing the installation and mounting of a MicroLogix 1500 programmable controller. For more information, please see the manufacturer’s guide installation instructions HERE.

And if you’ve have any comments, questions, or corrections, please feel free to fill out the “post a comment or question” for at the bottom of the page.
