Last week, as I was looking through the public documents available from Rockwell Automation’s TechED, I came across something very unexpected.
UPDATE: The 1756-L85E is now officially announced – find out more details HERE.
On slide four of the “SY15 – Application Code Manager” presentation, there was a 1756-L85E controller listed in the sample project.
However, today there is only a 1756-L65 and 1756-L75 available, and neither of those models have the trailing “E” in their part numbers.
I guessed that this indicated Rockwell was nearing the release of it’s next generation of ControlLogix processors, the 5580 line.
And based on the part numbering scheme used for the CompactLogix processors, I assumed the trailing “E” indicated this processor would have a built-in Ethernet port as well.
Curious to see if I could corroborate my hunches, I navigated my browser over to Rockwell Automation’s website.
Not finding any new announcements or literature related to the L85E, I turned to searching the Rockwell website.
This resulted in two hits, both links to the “declaration of conformity” documents listed below:
Reading these documents it became very clear that not only was the 1756-L85E listed alongside the L6 and L7 processors, but it was also described as having a built-in 1gb Ethernet port as well:
Note: The above appears to indicate a 64mb L76 is also on the way…
If you know anything more about the new 1756-L8xE line of processors I’d love to hear from you!

A fellow Integrator was sharing their experience since they were able to demo the L8X processor. They tested it on a program which had a 500ms scan time on a L73 and with the L8X it had……..15ms!!!!!!
Good afternoon Matt,
From 500 to 15… WOW!
Thanks for sharing that with us!
Sincerely,
Shawn Tierney

Thanks for sharing the link Chefe,
There’s a lot more information in our updated article below:

Rockwell decided to split form Intel when Intel kept shifitng inventor production numbers/dates.
Good afternoon Terry,
I heard that too – and that the resulting chipset Rockwell created was extremely fast!
Can’t wait to try it out,
Sincerely,

The 1756-L85E and 1756-L83E are
Logix 558X controllers with internal 8MB memory storage (L83E) or 32MB internal memory storage (L85E). They contain a 4 character alphanumeric display for information and diagnostic purposes, built in backup power, one high speed Gigabit Ethernet Port for communication, one USB port for initial programming and a Secure Digital memory card interface for a standard SD card. The 1756-L83E uses 8MB of embedded flash memory. The 1756-L85E uses 32MB of embedded flash memory. These controllers with memory will utilize the new ICE2 ASIC as their host CPU. The ICE2 ASIC has a quad-core Cortex-A9 architecture which will allow for separation of main logic execution from auxiliary functions such as communications and packet processing. This equipment utilizes three cores of the ASIC.

Great find!
Thanks!

There seems to be a 1756-L83E also (Korean Document):

Nice find! Thanks for sharing,

Can’t wait to read performance specs.
I have a few L73’s that have scan time close to 200ms that could use some upgrade…
I don’t think Ethernet port will replace EN2T or similar modules, but will allow access to CPU for Studio. Was RS232->USB->Ethernet. Normal evolution path.
Good morning Wojciech,
I hear you – I’m also looking forward to the official announcement – the rumors I’ve heard are quite interesting,
Thanks,

Shawn,
Thought I’d share what I know about the new Controllogix. I’m pumped for it’s release since I’m into embedded design, and I’m an Electrical Instrumentation tech. I recently took part in an automation expo in the Twin Cities and Rockwell was there highlighting the Integrated Architecture line so I figured I would ask the rep about the L8 series. He said the CPU is being developed through an exclusive partnership with Intel, and the controller will feature 1gbE as standard. The L8 series also utilizes a multicore processor, which has a services-based OS using virtualization to split up tasks on multiple cores. For example, the Rockwell rep said the gbE port will have it’s own dedicated core. Pretty cool stuff
Thanks John!
