SYSMAC CP1L/CP1E Introduction Manual
By using Modbus-RTU easy master function, Modbus-compliant slave devices (i.e.
inverters) can be controlled easily via serial communication.
CP1L
To perform serial communication on CP1L, install an optional serial communication
board (RS232C or RS422A/485). 14/20-point I/O units can have 1 optional serial
communication board installed. 30/40/60-point I/O units can have up to 2 boards
installed. CP1L 10-point I/O units cannot install option board. For CP1E, only N-type
30/40-point I/O unit has 1 optional serial communication board.
The Modbus-RTU easy master function allows for easy communication with
components connected via a serial connection board.
