hello, i have a project with controller redundancy, the X20 controllers are connected to each other with the redundancy Link (fiber optic), each PLC also has bonding between the ETH port and the PLK port. does the system know when the Ethernet process bus is disconnected (from both ports) and perform a redundancy switchover?
thank you.
I believe this is not done automatically, however you can implement this in your application code quite easily.
-
Monitor the status of the ETH Bond with the ArEthBondGetData() function block, this will give you the status of both ports.
-
If both ports are disconnected you can decide whether to execute a redundancy switchover manually with redSwitchover().
thank you i will test it
what is the bond name? where can i find it?
The bond name is the primary ethernet interface’s “PLC address”. If you are using the built in Ethernet interface of a X20CP3685 for example this would be “IF2”.
thank you. it is working.
