Unit Versions
Function Support by Unit Version
Functions Supported for Unit Version 4.0 or Later
CX-Programmer 7.0 or higher must be used to enable using the functions added for unit version 4.0.
Additional functions are supported if CX-Programmer version 7.2 or higher is used.
CJ1M CPU Units
User programs that contain functions supported only by CPU Units with unit version 4.0 or later cannot be used on CS/CJ-series CPU Units with
unit version 3.0 or earlier. An error message will be displayed if an attempt is made to download programs containing unit version 4.0 functions to
a CPU Unit with a unit version of 3.0 or earlier, and the download will not be possible.
If an object program file (.OBJ) using these functions is transferred to a CPU Unit with a unit version of 3.0 or earlier, a program error will occur
when operation is started or when the unit version 4.0 function is executed, and CPU Unit operation will stop.
Functions Supported for Unit Version 3.0 or Later
CX-Programmer 5.0 or higher must be used to enable using the functions added for unit version 3.0.
CJ1M CPU Units
User programs that contain functions supported only by CPU Units with unit version 3.0 or later cannot be used on CS/CJ-series CPU Units with
unit version 2.0 or earlier. An error message will be displayed if an attempt is made to download programs containing unit version 3.0 functions to
a CPU Unit with a unit version of 2.0 or earlier, and the download will not be possible.
If an object program file (.OBJ) using these functions is transferred to a CPU Unit with a unit version of 2.0 or earlier, a program error will occur
when operation is started or when the unit version 3.0 function is executed, and CPU Unit operation will stop.
