CP1H/CP1L CPU Unit
(except CP1L-L10)
Serial Communications
A Standard USB Port and Two Serial Ports Enable Connecti ons and
Communications with a Wide Range of Components.
Up to two Option Boards can be mounted for RS-232C or RS-422A/485 communications. A peripheral
USB port has been added to connect to a personal computer for a total of three communications ports,
making it easy to simultaneously connect to a PT, various components (such as Inverters, Temperature
Controllers, and Smart Sensors), Serial PLC Link for linking to other PLCs, and a personal computer.

CP1H/CP1L
CPU Unit
When multiple boilers are being controlled, up to 10
words/Unit of data for settings and monitoring can
be exchanged using data links between up to nine
CP1H, CP1L, and CJ1M CPU Units. Serial PLC Links
can be used with either serial port 1 or serial port 2.
Note: Cannot be used for the CP1L-L10.
Connecting inverter speed control is made simple
using the Modbus-RTU Easy Master.
When the address, function, and data for a slave
device are preset in a fixed memory area (DM Area),
a message can be sent or received simply by turning
ON an AR Area bit (A640.00 for port 1 or A641.00 for
port 2) in the PLC.
OMRON Function Blocks are provided for operations
such as run/stop, frequency settings, and monitoring
when connected to Inverters by serial
communications, and for setting SPs and reading
PVs for Temperature Controllers.
Serial PLC Links
Modbus-RTU Easy Master
The OMRON Function Blocks provide
function blocks for communicating with
Inverters and Temperature Controllers.

(1:N NT Link connections)
to exchange data using
the NT Links with only the
