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

Communication cycle coexistence

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

(2) Normal speed
(3) Low speed
Setting method
The master station communicates with slave 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 95 Communication
period setting)
The communication cycle of each slave station can be selected from "Basic Period", "Normal-Speed", or "Low-Speed" in
"Network Configuration Settings" under "Basic Settings".
Precautions
When "Communication Mode" under "Application Settings" is set to "Multicast", set "Communication Period Setting" for the
local station in "Network Configuration Settings" to "Basic Period".
