CJ1G/CJ1H CPUs Mean Optimized Performance
JFeatures Enhancing Flexibility
and Functionality
•0.02 µs execution time per basic instruction.
•Ultra-compact design.
•Built-in flash memory for battery-free operation.
•Up to 64 MB of auxiliary flash memory available for
many time-saving programming uses.
•The efficiency of transfers between the CPU and
Special I/O Modules has been optimized, further
improving overall system performance.
•Floating-point decimal numbers can be easily
converted to ASCII character string data for display on
an HMI (in the HMI’s character string display objects).
•For process control applications, use the PID WITH
AUTOTUNING instruction to calculate PID constants
automatically. Using the limit cycle method for tuning,
autotuning is completed quickly. This is particularly
effective for multi-loop PID control.
•Built-in peripheral and RS-232 ports.

JSerial PLC Link Communications
Simple PLC Link provides a quick and easy-to-under-
stand data link among up to 9 nodes on a serial network.
Each node is allocated 10 words of data, and two meth-
ods of sharing the data are user-selectable. An Omron
Operator Interface Terminal can be used on this network
where it counts as one slave node.
Features
•Capabilities: 10 words per PLC can be allocated to
PLC Link in a master/slave arrangement.
•Network size: 1 master and 1 to 8 slaves (total of
9 CJ1 PLCs) can exchange data.
•Medium: RS-232, using port built into each CPU.
•Hardware: CJ1W-CIF11 RS-232C to RS-422/485
converter for multi-drop.

Manipulate Files During Operation
File read and write instructions can be used
during operation to transfer files between
the CPU’s memory and Memory Cards (or
EM File Memory). Trend data, quality control
data, and other data from memory can be
stored during operation in Memory Cards or
EM File Memory.
Change the Program by Simply Changing Cards
File data can be automatically transferred from

modem; use an instruction to switch to host link mode, and then
program or monitor from CX-Programmer. (It’s not necessary to cut the
connection during the procedure.)
•Use the host link gateway function to program or monitor any
CJ1/CS1 Series PLC connected to a Controller Link or Ethernet
Network. A computer running CX-programmer will be connected (via
RS-232C) to a PLC somewhere in the network.

Programming and editing a PLC on a
remote network
•Use the gateway function to edit any PLC connected to a network up
to two networks away (3 networks including the local network). For
example, a PLC on the Controller Link Network shown below can be
accessed from CX-Programmer running on a computer connected to
a PLC on the Ethernet Network.

more than one program block can be edited at the same time.
Program protection Overwrite protection: Set using DIP switch.
Copy protection: Password set using CX-Programmer.
Error check User-defined errors (i.e., user can define fatal errors and non-fatal errors).
