Communication Cycles Coexistence - Mitsubishi Electric MELSEC iQ-R Series User Manual

Communication cycles coexistence

When slave stations with different communication cycles are included in the network, multiple communication cycles
according to each slave station are used for communications.
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.
No.0
(1) Basic cycle
(2) Normal speed
(3) Low speed (for "16")
Setting method
The master station communicates with slave stations by using three communication cycles that is the basic cycle under "Basic
Period Setting", and "Normal-Speed" and "Low-Speed" under "Multiple Period Setting". ( Page 80 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".
