Communications Cycle Time Setting
Communications Cycle Time Tab Page (Device - Parameter - Edit)
The communications cycle time setting and the communications cycle times calculated based on the current-
ly registered device information can be accessed on the Communications Cycle Time Tab Page.
Click the Communications Cycle Time Tab to display the following window.
The communications cycle time is set between 1 and 500 ms. Click the Default Setup Button or specify 0 ms
to enable automatic setting.
The communications cycle time for the automatic setting is calculated and displayed for each baud rate
based on the currently registered device information.
Note: The communications cycle time is the interval at which remote I/O communications are performed for
the same slave. Setting this time can prevent fluctuations in the communications cycle time based on
conditions. Setting a longer communications cycle time can prevent a slave with a slower processing
speed from being detected as having an error.
If actual remote I/O communications take shorter than the communications cycle time setting,
remote I/O communications will wait for the communications cycle time to expire. If the actual remote
I/O communications take longer, the remote I/O communications are performed in the actual time
interval regardless of the communications cycle time setting.
