Modbus Variables Freezing - CI867 - Error Message: "Fault Comm WD Time"
Dear,
I have some Modbus Variables frozen after the erroe messagem "Fault Comm WD Time" appear in a MBTCPComm control module.
It's a CI867 under a AC 800M controller in a 800xA 5.0 SP2 RevD.
Do you know how to restablish it?
Regards,
Marco
Answers
Hello,
just sharing... It was a communication failure due to the time difference between control network and the Modbus slave system.
After fixing the time issue and reseting the slave, variables were back.
