Interrupt From A Programmable Controller Cpu Module (Another Cpu Module) - Mitsubishi Electric MELSEC iQ-R Series User Manual

Interrupt from a programmable controller CPU module (another
CPU module)
The following explains the method for restarting a user program that is waiting for an interrupt event by the interrupt from a
programmable controller CPU module (another CPU module).
ÒExecute the
CCPU_WaitEvent
function.
: Execute the CCPU_WaitEvent function with the user program of this product.
The user program will be in the interrupt event wait state.
: Execute the D(P).GINT instruction with a sequence program of a programmable controller CPU (another CPU module).
An interrupt event is notified to this product.
: After this product receives the interrupt event notification, the user program restarts.
