We received recently several "Comm error or dynamic disable, device: CRM2_SVR : T4" alarms from two of our GE 9FA MKV controlled GT's. Whenever these alarms occur, we lose the HMI displays momentarily. After the HMI's starts displaying properly, we see that the time and date on the main HMI screens are wrong like 27th Oct. 2010, 6th Nov. 2017, etc. Computer time is also changed to a wrong value. Also every time the alarm mentioned above occurs, the time and date changes to another wrong value.The <RST> cores display A7 but their time display is wrong like the HMI's. We have Cimplicity 3.5 installed in our HMI's and we use Bancomm time sync board.
We took several actions including power and data cable separation check, EEPROM upgrade, restarting TCI, using DATE and TIME commands to see the current time/date (which seems to be correct), checking connections but none of them seem to help. Rebooting the cores (including <C>) may make things right but the unit is working right now.
Any comments and suggestions will be most appreciated,
Thanks
