how to set parameters of a ci853 card to detect an open loop on the passive line
in our systems we use redundant ci853 with modbus. Each line is connected to a computer, one active and the other in standby. Our task is to detect an open loop on the standby machine.
Is this possible by parameterization? Which parameters can be used for this (Xon/Xoff, hardware...)?
Or is it only possible with monitored switches. Has anyone ever realized something like this and can provide us with a sketch?
Thanks and greetings
