1 Set to transfer data with external devices using a full-duplex communication system when the Q series C24 is started. For switching to a half-duplex communication system, refer to the User’s Manual (Application).

2 Indicates possible combinations when connecting the PLC CPU and external devices (external device side: PLC CPU side). The total number of n and m+n is up to 32 stations.

3 In order to use the Q series C24, it is necessary to set the GX Developer switches. To set the GX Developer switches, refer to section 4.5.

4 Recommended cables SPEV (SB)-MPC-0.2 3P and SPEV (SB)-0.2 3P are equivalent in the electrical characteristics, but partially different in the outside diameter, internal wire colors, etc.

5 See Section 3.2.1 (3) for the recommended connector.
