*1 This is not restricted by the module mounting position, maximum number of mountable modules, or the number of CPU modules when
using a multiple CPU system configuration. (Same as when not using the inter-module synchronization function.) ( MELSEC iQ-R
Module Configuration Manual)
*2 In the multiple CPU system, the inter-module synchronization function can be used only by the network module controlled by the CPU
No.1.
*3 If the local station is designated as the module targeted for the inter-module synchronization function, the master station on the same
base unit as the local station cannot be set as a module targeted for the inter-module synchronization function.
Master station
Local station
*4 A hub compatible with the inter-module synchronization function must be used. ( MELSEC iQ-R Ethernet/CC-Link IE User's Manual
(Startup))
*5 Shows the type of station that can be selected with the station type setting. ( MELSEC iQ-R CC-Link IE Field Network User's Manual
(Application))
*6 To use the module on the local station as the synchronization target module, Inter-module Synchronization Master Setting is required.
