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 communication cycle.
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 135
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".
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".
