Features and Main Functions
Section 1-1
Note
(1) The Modbus-RTU easy master (available for all models) makes it easy to
control Modbus Slaves (such as Inverters) with serial communications.
After the Modbus Slave address, function, and data have been preset in
a fixed memory area (DM), messages can be sent or received indepen-
dently of the program by turning software switches.
(2) By using the serial PLC Links (available for all models), a maximum of 10
words of data per CPU Unit can be shared independently of the program
among a maximum of nine CPU Units (CP1H-CP1H-CJ1M) using RS-
422A/485 Option Boards.
7-segment LED
Display (All Models)
A two-digit 7-segment LED display makes it easy to monitor PLC status.
This improves the human-machine interface for maintenance, making it easier
to detect troubles that may occur during machine operation.
• Displays error codes and details for errors detected by the CPU Unit.
Modbus-RTU
Communications can be executed independently of
the program by setting a Modbus-RTU command in
the DM and turning ON a software switch.
