PROCEDURES BEFORE OPERATION
This section describes the procedures for using the inter-module synchronization function.
1.
Starting up the engineering tool
Connect the personal computer in which the engineering tool is installed to the CPU module or remote head module, and start
up the engineering tool. ( GX Works3 Operating Manual)
For details on the preparations for starting up the engineering tool (mounting the modules, wiring each device,
turning the system power ON, etc.), refer to the following.
 MELSEC iQ-R CPU Module User's Manual (Startup)
 MELSEC iQ-R CC-Link IE Field Network Remote Head Module User's Manual (Startup)
2.
Setting the applicable system
Set the system used in the unit configuration drawing. ( GX Works3 Operating Manual) When using the multiple CPU
system configuration, set the system parameters for all CPU modules. ( MELSEC iQ-R CPU Module User's Manual
(Application))
3.
Setting the inter-module synchronization function
Set the parameters required for using the inter-module synchronization function.
• Inter-module synchronization setting (Page 34 Inter-Module Synchronization Setting)
• If necessary, set the CPU parameters and module parameters. (Manual for each module)
• To coordinate the multiple CPU system function's fixed scan communication cycle with the inter-module synchronization
cycle, set the fixed scan communication setting. (Page 36 Multiple CPU Settings)
• To coordinate the CC-Link IE Field Network synchronous communication function with the inter-module synchronization
cycle, set the CC-Link IE Field Network master station. (Page 37 Settings in CC-Link IE Field Network)
4.
Programming
Create the inter-module synchronous interrupt program. To exchange the data used with the inter-module synchronization
function between the multiple CPU systems, create a program for exchanging data.
5.
RAS setting
If necessary, set to monitor the inter-module synchronous interrupt program's execution time. (Page 48 Inter-module
synchronous interrupt program execution time monitor)
6.
Writing the parameters and programs
Write the parameters set with the engineering tool and the created program into the CPU module or remote head module
( GX Works3 Operating Manual) When using the multiple CPU system configuration, the parameter settings and program
must be written into each CPU module for CPU No. 2 to 4.
*1 Programs cannot be written into the remote head module. Write programs to the CPU module on the master station.
7.
Restarting the system
Restart the system with one of the following methods.
• Power OFFONRUN
• Reset the CPU module or remote head module  RUN
8.
Monitoring and diagnosis
If necessary, confirm the operation of the inter-module synchronization function with the system monitor or the interrupt
program monitor list for each CPU module. (Page 46 Error Processing and Recovery Methods)
