strantor2 (Customer) asked a question.
I have a productivity 3000 PLC project that I've just recently completed, and the development was plagued with frequent unplanned, unannounced, and unexplained stop modes, as the title says, following run mode project transfers. After each run mode transfer there would be about a 30 second window where I would be crossing my fingers and mentally prepared to get kicked offline from the PLC, have my estops reset, lose all my non-retentive data, and have to walk around re-initializing the line. There would be no error or event in the logs, no error displayed on the CPU, no indication at all that anything had gone wrong, just the tell-tale of solenoids clicking all around me as they lost power and getting kicked offline, to find all non-retentive values at zero upon reestablishing connection. It would happen, I'd say, in about 1 out of 4 or 5 downloads.
On top of that, in maybe 1 out of 20 or 30 downloads, I would also lose some retentive tags. I don't think I ever lost all of them, and it seemed kind of random what I lost, but it didn't happen enough times for me to be able to establish any pattern to what was lost.
One time, following one of these "grand mal" seizures, I found a "watchdog timeout" error in the error log upon reestablishing communication, but all other times, nothing.
I've never had this happen before, but I did have a productivity 2000 project in the recent past, where I would get random outputs cycling during a run mode download. But I never had anything like I just described above. Never any data loss.
Anyone else experienced anything like this? Is it a known issue? Is there anything to avoid doing, to mitigate it?
Maybe post (or DM to AD Tech) the CPU datecode (label on the side of CPU) <- depending on whether you consider this info sensitive.
Post which P3-550 model, hardware rev, firmware rev, sw rev..
I assume that the CPU Online Module Information dialog's 'Module Rev. Level' equates to 'hardware rev.'
to add to @kewakl post I would recommend just going online with the CPU and creating a system report (all boxes checked) and PM that to me and I will forward over to our QA test team for review.
even better idea^
How long should this take? After 10 minutes still spinning the wheel
Nahhh, that is not a good sign!
What does it indicate?
recommend unchecking the two checkboxes and run the system report again.
After having to perform this same thing (create a system report) I'd like to point out it is located under HELP.
To further explain, I was on team viewer with a customer's machine today and needing to get a system report "just in case" and knew of this thread but was dumbfounded finding where "Create System Reprot" is located in Psuite. Under "HELP" wasn't obvious to me as I was thinking it would be found under "CPU."
No one will find this response anyway. 😋
At the time, your post was the last post in this topic, but the PLC/Field I/O frontpage says that an 8 month post IS the latest!
I tried repeatedly to generate a system report early in the saga and the software would hang. I don't think I tried again after installing psuite 3.10. I will try again this morning.
