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 ------ ...

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 ...

In addition to Josh Hewitt's suggestion about the axis feedback configuration, I was also wondering whether you have your PLC loading from non-volatile memory on power-up and possibly overwriting the AxisHomedStatus. That was the gist of my question regarding PLC also powering down or just drives powering ...

Hi, So when you power the rack up again the AxisHomedStatus bit is low? The APRFault bit is high? Is this with only the servo rack powering down or is the PLC also being powered down? I am assuming Controllogix? What are the firmware versions of the Drive and of the PLC? I would ...
