16.13.2 Multi-drop method (RS-422 communication)
Using the RS-422 communication function can use to operate multiple driver on the same bus. In this case,
set station numbers to the driver because the PC or PLC...etc recognizes that the data currently being sent
is for which driver. Set station Nos. with [Pr. PC20 Station number setting].
Always set one station No. to one driver. Setting one station number to multiple driver will disable a normal
communication. When you use to operate multiple drivers under one command, use the group specification
function in section 5.5.3.
