■ Configuration of four modules (CPU No.1: RnENCPU, No.2 to No.4: Motion CPU)
• Actual system
• Module configuration diagram
When "Read Module Configuration from PLC" is performed while parameters are not configured, module
configuration is read according to the actual system. In that case, change the position of the RnENCPU
(network part) to the right of the Motion CPU at the rightmost position as described in this manual. After setting
parameters, the module configuration diagram keeps the setting of the parameters even though "Read
Module Configuration from PLC" is performed. (Module configuration that differs from actual system is
displayed.)
