Setting procedure
Setting synchronization cycles
■Calculating synchronization cycles
Calculate synchronization cycles from the formula below.
Synchronization cycle = Basic cycle Magnification
The following figure shows the synchronization cycle of each I/O module calculated based on the parameter of the master
station set as shown in the table below.
■How to set synchronization cycles
Set the synchronization cycles of the CC-Link IE TSN Network synchronous communication function at the master station.
For details, refer to the following.
MELSEC iQ-R Inter-Module Synchronization Function Reference Manual
• Basic cycle is determined by a value in "Communication Period Interval Setting", which is set in the parameter of the master station.
• Magnification is determined by a value in "Multiple Period Setting" and a value in "Communication Period Setting" of each remote station, all of which are set
in the parameter of the master station.
Item Description
Communication Period Interval Setting 250s
Multiple Period Setting • Normal-Speed: 4
• Low-Speed: 16
Communication Period Setting I/O module A Basic Period
I/O module B Normal-Speed
I/O module C Low-Speed
(1) Synchronization cycle of I/O module A = Basic cycle (250s) Magnification (Basic Period: 1) = 250s
(2) Synchronization cycle of I/O module B = Basic cycle (250s) Magnification (Normal-Speed: 4) = 1ms
(3) Synchronization cycle of I/O module C = Basic cycle (250s) Magnification (Low-Speed: 16) = 4ms
