*1: The distance between stations is restricted in accordance with the type of cable and number
of stations. Refer to Reference Manual of master module in use for details.
*2: Specialised training and specific tools are required to connect the connector to the
optical-fiber cable; the connector itself is a custom product. Please contact your nearest
Mitsubishi Electric System Service Corporation when purchasing these items.
For general specifications of the network module, refer to the user's manual for the PLC CPU
