Question:
How does Driver starts in listen mode option behave when enabled?
Solution:
Listen Mode happens when the driver is able to ‘listen’ to the connection of another master/slave. The driver then will simply retrieve the values of the tags in traffic and make them available for reading as if it were the master.
This will not work on Ethernet though, unless the device makes available a port where all communication taking place with another master is doubled, and send all data received and sent by other port via this port. Otherwise, it will only work in Serial mode, and if communication takes place via RS485.
Further information can be found in the manuals of the drivers offering this option.
