not a syntac error if K or H constant is specified as S1 and D.
Operation
It is used to send commands to the serial port (COM1 or COM2) of the specified unit in the MODBUS
mode connecting the unit that enables to receive the MODBUS command. (MODBUS command 05,
06, 15 and 16)
The data of the local area specfied by [S2] is written in the area of the remote unit specified by [D] and
[N], according to the specification for the 2−word data stored in the control data with starting area
specified by [S1].
