If the line is not disconnected from GX Developer within the specified time in this area, the Q Series C24

forcibly disconnects the line, terminating callback processing.

This specifies the time from the temporary line disconnect on the GX Developer side until the Q Series C24

reconnects (callback).

Refer to the Q Corresponding Serial Communication Module User's Manual (Basic) for the symptoms, causes, and actions

of problems that may occur during access from GX Developer to the QCPU when using the callback function.
