Which Modbus TCP driver to use in Vijeo Designer?

Issue: It is unclear which Modbus TCP/IP driver to use in Vijeo Designer.

Product Ranges: Vijeo Designer (all versions)

Resolution: To select the correct driver, you must determine if the device to connect to is a Modbus Master or if the device is a Modbus Slave.If the device is the Modbus Master, the best driver to use is the Modbus TCP Slave driver of Vijeo Designer.
