(3) To monitor the programmable controller CPU, the Q series C24 reads
monitoring information (device information, programmable controller CPU
status information) from the programmable controller CPU at time intervals set
by the user.
● Since the Q series C24 reads the monitoring information (device data, programmable controller CPU status) at the time
of the next programmable controller CPU END process after the cycle time elapses, make the cycle time as long as
possible.
● The following should be considered if the cycle time is short.
• The scan time of the programmable controller CPU is longer and the number of scan cycles has increased.
• The increase in the processing time of the Q Series C24 programmable controller CPU monitoring function has
increased causing an increase in the processing time of other data communication functions.
• The load on the external device has increased.
