Order of Installation

  1. Prepare the components for system configuration.

  2. Mount a communication module in the state that the power for a PLC is not supplied.

  3. Make sure there are dust and remains in the connecter of the base where the communication module will be mounted and whether the connecter pins of the communication module are broken.

  4. The maximum number of modules mounted on one base is 8.
    When you mount this module, insert the connecting part on the bottom of the module to the slot of a base exactly in the state that the communication cable is not connected and press the power sufficient to lock the module to the base completely. Otherwise, an error in the interface with CPU may occur.

  5. Tighten the screws at both ends of the RS232C cable to secure connection.

  6. Input the power after connecting the communication cable. Make sure whether the module is operated normally, observing the operation of the LED. In case of normal operation, select the menu to set up various parameters for the communication module and to download the program to run.
