Does RJ45 port of ATV212 is suitable for modbus serial communication.
RJ45 connector of ATV212 drives is factory set to connect graphic display terminal. So, when using RJ45 connector
on Modbus serial communication bus then, it is mandatory to set parameter F807 [Com Channel Choice] =0 ( default set to 1).
By setting F807 to value 0, drive responds to Modbus command sent through RJ 45 port from modbus master device.
