(b) Interrupt to C Controller module (another CPU)
When an interrupt is issued to a C Controller module (another CPU), the C
Controller module (another CPU) performs the following processing.
• Executes a routine registered by the QBF_EntryCpuInt function as an
interrupt routine (interrupt program).
*1
• Resumes the user program that is waiting for an interrupt event by the
QBF_WaitEvent function.
* 1 The following C Controller modules cannot execute it as an interrupt routine (interrupt program).
(2) Function
The following function is used for an interrupt to another CPU (Motion CPU or C
Controller module).
Remark
For the bus interface functions, refer to the following.

Function name Function
QBF_GINT
Issues an interrupt to another CPU.
This is equivalent to the S(P).GINT or D(P).GINT instruction of a
programmable controller CPU.
