Suddenly stopped communication of my redundant controllers with Automation Builder
I was working to establish the redundancy of my controllers that was also done, and suddenly all 4 devices 2* CM597 and 2* PM573-eth stopped communication with Automation Builder logic.
What i have done
1. I changed ethernet cable, tried to ping seperate devices.
2. Used IP Configuration to scan all.
3. Power Off / On, but one controller Runs once and stops, other controller is always stop.
4. No power failure during running system.
During going to online or to downlod the program, everytime it gives an error
"Communication Error (#0): Logout Performed"
Suddenly what happen, and what should be the solution, please suggest me.
Thanks in advance.
