Hi lingampelly, It has been a while since I had to modify a devicenet network. In a quick offline setup in RSNetworx I had to remove the Flex adapter from the scanlist and re-add it for the amount of input data to update in the scanner's input mapping. I can't remember for sure, but you may have ...

RE: Generic 1756-Generic Module Profile Crashes

Found In Egroup: Automation Control \ view thread
I already have v38.02 (07/2026) installed, which is even later than v34.05 (12/2025), so I should already be at the latest AOP host, shouldn't I? I think this is indicated by the Core version 32.14.11.0 shown in the screenshot, but maybe I am wrong. A colleague who has v34.01 was able to create ...

RE: What version of RSLogix 500 and RXLinx to open a MicroLogix 1400 series C program that has been saved in 500 V 12?

Hi Steve. To program a ML1400 you would need minimum v8.30 of Logix500. You would need v11 or greater to utilize the password feature introduced in FRN21. They did not add a Series C processor selection in Logix 500, but series C functions the same as series B; just hardware changes, I believe. ...

Ah, in that case the 20-750-ENETR or 20-750-ENET2P are your best options, which can be purchased separately. More information available here: ID: QA34443 | Access Levels: Everyone PowerFlex 753: EtherNet Options Hope it helps. ------------------------------ Regards, RM ------ ...

Hi HogueGregPLC, Short answer is that the 523 does not come with ethernet as standard. I think this technote should give you most of the information you seek: ID: QA31864 | Access Levels: Everyone PowerFlex 523, 525, and 527 Comparison and Communication Options Hope it helps. ...

Does nothing show up in the S2 bits when this happens? I would guess a processor error occurred that kicked it out of Run Mode. Alternatively it could have lost power and is not configured to go to Run Mode on Powerup. Regards, ------------------------------ Regards, ...

Well, you'll notice that those two fields you pointed to, Out_LogicCommand and Out_FreqCommand point to specific elements of the data type. Those elements are part of the base data type and don't change so you're good there. This was kind of what I meant by intermediary UDT, the way they are copying ...
