Communication Cycle Time Settings
Device - Parameter - Edit - Communication Cycle Time Tab
Note This procedure is the same for the CS1W-DRM21,
CJ1W-DRM21, CVM1-DRM21-V1, and C200HW-DRM21-V1.
It is possible to set the communication cycle time on the Communication
Cycle Time Tab Page. Furthermore, it is possible to check the present com-
munication time calculated from the registered device information.
The following window will be displayed by clicking on the Communication
Cycle Time Tab.
Set the communication cycle time between 1 and 500 ms. To set the commu-
nication cycle time automatically, click the
Default Setup
Button or set the
communication cycle time to 0 ms.
The communication cycle time set will be automatically calculated and dis-
played according to the registered device information and the baud rate.
Note
Communication cycle time refers to the required time of remote I/O communi-
cations between the master and a slave. Communication cycle time settings
properly made will prevent the fluctuation of the time of remote I/O communi-
cations with the slave. Furthermore, by setting the communication cycle time
to a larger value, the prolonged processing operation of the slave will not be
treated as a communications error. If the actual remote I/O communications
time is shorter than the set communication cycle time, the remote I/O commu-
nications will keep pace with the communication cycle time. If actual I/O com-
munications take longer than the set communication cycle time, the I/O
communications will be continued regardless of the set communication cycle
time.
