Issuing An Interrupt To Another Cpu - Mitsubishi Electric MELSEC Q Series User Manual

14.4

Issuing an Interrupt to Another CPU

This function allows the C Controller module to issue an interrupt to another CPU (Motion CPU or C Controller module)
from its own user program.
No interrupt can be issued to a programmable controller CPU.
(1) Interrupt to Motion CPU
When an interrupt is issued to a Motion CPU, the Motion CPU starts an interrupt program.
(2) Interrupt to C Controller module (another CPU)
When an interrupt is issued to a C Controller module (another CPU), Resumes the user program that is waiting
for an interrupt event by the Bus interface functions (QBF_WaitEvent function.)
