Answer question
The controller PM865 suffered a fatal error
Hi,
I have redundant AC800M controllers. During smmoth operation of the process both the controllers went into Fault mode with Fault LED blinking. The power supply to the controllers was intact. The log file shows the following statement:
{The controller has been shutdown due to an unrecoverable fatal state!!
Press init button or remove power to restart...
This PM has been automatically restarted.
Reason:
- restarted from an unrecoverable fatal state}
The log files are atatched. Could someone please explain what exactly could have caused both the Controllers to go into Fault state ?
Thanks
