6-5-1 Configuration and Procedure
6-5 Connecting to CJ-series PLCs
The following configuration is used as an example in giving the setup and application procedures for
programless communications.
• All of the E5CC Controllers must be the same model. (Copying parameter settings is not possible if
the models are different.)
• D0000 to D0089 are used in the PLC memory. The default E5CC parameter allocations are used.
• A commercially available USB2.0, A/B cable is used.
Note: Refer to the CX-Programmer Operation Manual (Cat. No. W446) for information on installing the
CX-Programmer and USB driver.
The application procedure is given below.
