Perform communications processing (explicit
message communications) with the DeviceNet
Master.
Note
2. The maximum cycle time and current cycle time are stored in AR 14 and
3. The cycle time varies with the processing required and so it is possible that
1. The CPM2B-S starts I/O refreshing after CompoBus/S communications
2. Even if the CompoBus/S is not used, the cycle time will never be shorter
3. The cycle time will be affected if there is a connection to a DeviceNet net-
AR 15 respectively.

are completed. If the cycle time is shorter than the CompoBus/S commu-
nications response time, the CPU will wait until CompoBus/S communica-
tions are completed before starting I/O refreshing again. In effect, this
delay results in a minimum cycle time equivalent to the CompoBus/S com-
munications response time.
