not a syntac error if K or H constant is specified as S1 and S2.
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 01,
02, 03 and 04)
The data is sent from the area of the remote unit specified by [S2] and [N], and is stored in the area of
the local unit that starts with [D], according to the specification for the 2−word data stored in the control
data that starts with the area specified by [S1].
