Today I was troubleshooting a machine that is acting oddly. I wanted to compare the current plc program that I had open and was on-line with to a previous version
So I opened another instance of RSLogix 5000 and then opened a year old version of the plc program. I did not go on line with that one.
Well that messed up my view of the on-line RSLogix5000 session.
Okay, I'll close both instances of RSLogix 5000, that will make it right.
Re-opened my current version of the PLC program and it looked fine, I went on-line and I had a rung that I'd been viewing that had all branches, no instructions and the e along the rung.
Meanwhile the machine is merrily running along. I went and got help / a witness. My coworker plugged in his laptop, went online, the program looks great. He saves a copy to his laptop.
I decide to reboot the pc that I run RSLogix5000 on as it must be corrupt some way. We load the program file I was using and when we went online it showed that rung missing most of the instructions now.
Finally, my coworker took the file he saved on his computer after going online to correlate with controller, opened it up on my computer and all is good.
Is what I was attempting to do not allowed? The online version is named something like project_20170719a.ach and the old version project_20160413a.ach so they are different disk images.
Thanks
