Communication Cycle Coexistence - Mitsubishi Electric MELSEC iQ-F FX5 Series User Manual

Communication cycle coexistence

When device stations with different communication cycles are included in the network, communicates data using multiple
communication cycles according to each device station.
The time for each communication cycle is the total time of cyclic transmission, transient transmission, and system reservation
time.
Even if device stations with different communication cycles are connected to a network, a device station with a high-speed
communication cycle is not affected by a device station with a low speed.

Setting method
The master station communicates with device stations by using three communication cycles that are the basic cycle under
"Basic Period Setting", and "Normal-Speed" and "Low-Speed" under "Multiple Period Setting". (Page 103 Communication
Period Setting)
The communication cycle of each device station can be selected from "Basic Period", "Normal-Speed", or "Low-Speed" in
"Network Configuration Settings" under "Basic Settings".
