(b) Starting the interrupt program by an interrupt request to the CPU module in every
operation cycle
An interrupt request to the CPU module can be executed in every operation cycle
by using Operation cycle interrupt request (SB000C) of link special relay (SB).

1) Set the interrupt setting parameters for the Simple Motion module (station
number 0) in the "Interrupt Settings" window as shown below.
2) Set the parameters in the "Intelligent Function Module Interrupt Pointer
Setting" window as shown below.
POINT
• The interrupt request to the CPU module is executed when cyclic transmission is
completed. If cyclic transmission is not performed, the interrupt request to the
CPU module will not be executed.
• Run the interrupt program at the status that the operation cycle over of the Simple
Motion module does not occur. The operation cycle over of the Simple Motion
module is determined with ON/OFF of "[Md.133] Operation cycle over flag". When
the operation cycle over occurs, the interrupt program cannot start at the normal
timing.
• Complete the interrupt processing in the interrupt cycle.
