Modbus slave connection monitoring

[Maria]

Hello,

could you please help me to find out how is possible to monitor a modbus slave communication? I am using an USC-B10-B1 PLC.

I was thinking to use the slave succes variable but I do not know how to monitor the value change. Is there an onChange event available?

Thank you very much!

Make your own OnChange logic.  Copy the the Slave Success to a second tag on a regular basis and then compare the two.
