Features and Main Functions Section 1-1
Expansion Capability
for Serial Ports
Up to two Serial Communications Boards each with one RS-232C port or one
RS-422A/485 port can be added to a CPU Unit with 30 or 40 I/O points. One
Serial Communications Boards can be added to a CPU Unit with 20 I/O
points. With the serial communications port, it is easy to simultaneously con-
nect a computer, PT, PLC, and/or various components, such as an Inverter,
Temperature Controller, or Smart Sensor.
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.
