Hello, i’m trying to investigate the cause of a watchdog: [quote]Arp.Plc.Esm.Internal.WatchdogHandler ERROR - Watchdog of task ‚T_200‘ triggered. (watchdog time 200000us / time after task start 399820us)[/quote] After a watchdog, looking in debug mode at the system variable ESM_DATA.EXCEPTIONS_INFO I can’t find any kind of information (structure seem to be blank) I found a library at C:\\Program Files\\PHOENIX CONTACT\\PLCnext Engineer 2021.3\\Libraries the library Exception Infos.pcwlx, that contains the function block GET_EXCEPTION_INFOS. So, as suggested in the Help of PLCnext Engineer, I implemented an Exception Event Task and called inside this GET_EXCEPTION_INFOS. (I’ve already used this kind Event Task, without any problem) Unfortunately after the startup I have a FAIL and this is what I find in the Output.log file: [quote] 31.05.21 14:01:53.151 Arp.Plc.Gds.Internal.GdsMetaManager WARN - Compare type definitions: Incompatible offset, data type or alignment.

It seems to be executed only once. Thanks for your help! Marcello
Hi Marcello, I’ve just tried the Get_Exceptio_Info FB with Engineer 2021.3 and FW 2021.0.5 without any issues, I’ll forward the example to you by mail. I can also confirm that the Exception Task will only executed once, so you can use a loop, but no TONs. Take care, Frank
