Compactlogix V16 Minor Fault

[curlyandshemp]

Has anyone seen this error or know what it means. Today , when I was at the customers site doing some mods and upgrades, this error began appearing, whereas it has never appeared in the 1 month the compactlogix has been installed.

This app, has 1768-L35E V16(ours), 3 x 1768-L32E V15(others), 1 PV1000+ V4.0 and 2 PV700+ V4.0

Adjusting the CPU Overhead time slice made no difference in the error occurance. Use the Main task monitor, this task's maximum scan time was no more than 6ms and averaged 3ms

Did you try to increase the watchdog time in case that might be the problem?

Type 6 is definately watchdog, but I can't find any reference for code 4.
I think this is something compactlogix v16 specific.
I would contact techsupport and let them check with engineering.
