RS-485 Communication Features
7.3.4 Parameter Group for Data Transmission
By defining a parameter group for data transmission, the communication addresses
registered in the communication function group (COM) can be used in communication.
Parameter group for data transmission may be defined to transmit multiple parameters at
once, into the communication frame.

When registering control parameters, register the operation speed (0h0005, 0h0380, 0h0381)
and operation command (0h0006, 0h0382) parameters at the end of a parameter control
frame. For example, when the parameter control frame has 5 parameter control items (Para
Control - x), register the operation speed at Para Control-4 and the operation command to
Para Control-5.
