Interrupt Notification Reception - Mitsubishi Electric MELSEC iQ-R Series User Manual

12.3

Interrupt Notification Reception

This function waits for interrupt event notification from another CPU module, input module, intelligent function module, or
interrupt module.
By receiving interrupt event notification, this function can restart the processing of a user program that is waiting for an
interrupt event.
For details on functions and creating user programs, refer to the following:
MELSEC iQ-R MELSECWinCPU Module Programming Manual
When executing an interrupt request, module parameters of each module need to be set.
For details on the setting, refer to the user's manual of each module.
Function list
The following table shows functions to be used in a user program.
Function name
CCPU_WaitEvent
CCPU_WaitUnitEvent
*1 For an interrupt from a programmable controller CPU module (another CPU module), an interrupt request is issued by the D(P).GINT
instruction (a dedicated instruction that uses the CPU buffer memory (the fixed scan communication area)) or the M(P).GINT instruction
(a dedicated instruction that uses the CPU buffer memory).
For an interrupt from a C Controller module (another CPU module), an interrupt request is issued by the CCPU_DedicatedDInst function
(a function that uses the CPU buffer memory (the fixed scan communication area)) or the CCPU_DedicatedMInt function (a function that
uses the CPU buffer memory).
*2 An interrupt request that uses the fixed scan communication area can be used when this product is accessible to the area. (Page
