Cyclic Transmission Delay Time - Mitsubishi Electric MELSEC iQ-R Series User Manual

Cyclic transmission delay time

This section describes how to calculate the following cyclic transmission delay times.
• The time between the transmission source CPU module device turning ON or OFF and the transmission destination CPU
module device turning ON or OFF
• The time between data setting in the transmission source CPU module device and the data being stored in the transmission
destination CPU module device
In "Basic Settings" of the master station, when "Communication Period Setting" of the communication destination in "Network
Configuration Settings" is set to an option other than "Basic Period", multiply the LS (communication cycle intervals) by the
multiplier corresponding to the set option, which is specified in "Multiple Period Setting" under "Communication Period
Setting".
At this time, the multiple is as follows, depending on "Communication Period Setting" under "Basic Settings" and "CC-Link IE
TSN Class" under "Network Configuration Settings".
• For "CC-Link IE TSN Class B": The multiple specified in "Multiple Period Setting" in "Communication Period Setting" under
"Basic Settings"
• When "CC-Link IE TSN Class A" and "Communication Period Setting" are "Normal-Speed": The multiple specified in
"Multiple Period Setting" in "Communication Period Setting" under "Basic Settings"
• When "CC-Link IE TSN Class A" and "Communication Period Setting" are "Low-Speed": The multiple × n specified in
"Multiple Period Setting" in "Communication Period Setting" under "Basic Settings"
n can be checked with 'Device station cyclic transmission information' (Un\G1294304).
Stations with "CC-Link IE TSN Class A" where "Communication Period Setting" is set to "Low-Speed" are grouped by the
sizes of cyclic data sent from the master station to a device station or cyclic data which the master station receives from a
device station. The number n is determined by the number of the groups.
