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 programmable controller CPU and external devices
(external device side: programmable controller 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
electrical characteristics, but partially different in the outside diameter, internal wire colors, etc.
5 See Section 3.2.1 (3) for the recommended connector.
6 Pre-defined protocol communication is available for the QJ71C24N, QJ71C24N-R2, and QJ71C24N-R4.
