Hi,
Here are some information i would like to highlight from the controller logs,
1. Your IAC communication is not stable?, there are some repetitive connection ups and downs in IAC MMS
I 2020-08-18 16:25:53.573 IAC: Connection up (IP = AC105098)
W 2020-08-18 16:26:22.935 IAC: Connection down (IP = AC105098)
2. IAC communication variable timeout as well
E 2020-08-18 16:26:22.934 On Unit= 0.5.1 HWError Ctrl_VMS3 0000 See HWTree Error 16#60020000 16#00000020
3. There are some problem in CI card-1 - Profibus communication failure between Primary and Backup
E 2020-08-18 16:37:51.131 Unit= 1.4 Ctrl_VMS3 0000 See HWTree Error 16#02020000 16#40000000
4. Backup (Lower) CPU stopped first due to some RCU error. Not sure whether it is by manual or auto?
E 2020-08-18 16:41:26.762 Unit= _SWTargets Ctrl_VMS3 4004 P:BkpNotAlive in Synch
E 2020-08-18 16:41:26.761 Unit= _SWTargets Ctrl_VMS3 4020 B:Bkp RCUError 08
E 2020-08-18 16:41:26.761 Unit= _SWTargets Ctrl_VMS3 4024 B:Backup CPU halted
5. Am not sure what is this below bus error?, someone can enlight me on this
E 2020-08-18 17:19:48.466 AnyBusDevMgr BUSERROR at module 3 address 401c02c0
6. Finally, the controller shutdown
E 2020-08-18 17:19:48.497 ErrorHandler PM: 4112 Hang CEX IRQ The upper PM has been shut down (1,4,ER)
E 2020-08-18 17:19:48.497 Error message PM: 4112 Hang CEX IRQ The upper PM has been shut down
E 2020-08-18 17:19:48.500 FATAL ERROR in ..\..\source\BASICS~1/ErrorHandler/errorhandler/errorhandlerimp.cpp[1625]: 872939520 (0x34080000)
F 2020-08-18 17:19:49.563 (local time) System Breakdown Walkback trigged by exception vector : 0x1000
It points out so many issues, but could not able to conclude on what exact scenario it leads to shutdown. Network issue is an another angle to look into this issue.
Anyway Pls register a supportline case with ABB to get a official support on this.
