Inter-Module Synchronous Interrupt Program Does Not Run; A Specific Module Is Not Synchronized - Mitsubishi Electric MELSEC iQ-R Series Reference Manual

Inter-module synchronous interrupt program does not run

Check the following if the inter-module synchronous interrupt program does not run.
Confirmation items
Is the inter-module synchronization setting enabled?
Does an inter-module synchronous interrupt program
present?
Is the CPU module set to RUN?
Is interrupt permitted?
Has the inter-module synchronous interrupt program
been registered?
The inter-module synchronous interrupt program operating status can be checked with the interrupt program
monitor list. ( GX Works3 Operating Manual)

A specific module is not synchronized

Check the following if a specific module does not run.
Confirmation items
Is the inter-module synchronization function target
module set?
Is refresh set?
Synchronization of an arbitrary module can be confirmed with the system monitor. (Page 46 Error
Processing and Recovery Methods)
Action
Enable the inter-module synchronization setting if it is not enabled. (Page 34 Inter-Module
Synchronization Setting)
If the inter-module synchronous interrupt program is not present, add one.
Set the CPU module to RUN if it is not already set.
Execute the EI instruction if it hasn't been executed yet.
When C Controller module is used, register and enable the inter-module synchronous interrupt
program using the C Controller module dedicated function.(MELSEC iQ-R C Controller Module
User's Manual (Application))
Action
Set the inter-module synchronization target module if it is not set yet. (Page 34 Inter-Module
Synchronization Setting)
• Check whether a module label is used in the inter-module synchronization function and whether
the refresh destination device is used in the inter-module synchronous interrupt program.
• Review the refresh settings.
