CJ1-H-R CPU Units (High-speed)
Overview The CJ1-H-R CPU Units (CJ1H-CPU@@H-R) are high-speed versions of unit
version 4.0 of the CJ1-H CPU Units (CJ1H-CPU@@H).
Models
Note In the CX-Programmer, set the device type to CJ1H-H and the CPU type to
CPU67-R, CPU66-R, CPU65-R, or CPU64-R.
Differences Compared to
CJ1-H CPU Units
The CJ1-H-R CPU Units (CJ1H-CPU@@H-R) have the following differences
in comparison to the CJ1-H CPU Units (CJ1H-CPU@@H).
Note 1. Refer to the CX-Integrator Operation Manual (Cat. No. W445) and the
Communication Unit operation manuals for details.
2. The 0.01 s Clock Pulse cannot be used with unit version 4.1 of the CJ1-HR
CPU Units. The 0.01 s Clock Pulse can be used with all other unit versions.
