CJ1-H CPU Units
Note 1. CX-Programmer version 7.1 or higher is required to use the new function-
ality of CJ1-H-R CPU Units.
2. The values displayed in the table are valid when a CPU Unit with unit ver-
sion 4 or later is combined with CX-Programmer 7.0 or higher.
The following table shows the flash memory capacities for CPU Units with unit version 3.
Earlier CPU Units (unit version 2 or earlier) are not equipped with the function that stores data such as
