Hello all,
I am working on a project on a CompactLogix L16ER-BB1B plc, and I was given a program that is on version 20.019, while my plc is on firmware version 33.012. I tried loading the program on in studio 5000, and it seems like it loaded properly and all modules are communicating, but the program isn't working. (the program is supposed to control three stepper motors via ethernet, and they all show up and are communicating when viewed in Who Active.)
When I was given the plc, it had v20 firmware, and the program worked until I tried updating the plc and the program to the latest version to make changes. Is this something that could potentially break a program/prevent it from working? And ois there a way I can flash old firmware back into the PLC from studio 5000? I just want to check that the program will work if I put the 20.019 firmware back into the PLC.
Thanks
