Interrupt Request to CPU Module

Interrupt conditions are checked every link scan, and if the conditions are met, an interrupt is requested to the CPU
module to start the interrupt program.
Set interrupt conditions in "Interrupt Settings" for each station. (
● Interrupt program start of the own station can be instructed from another station.
● Since a part describing the start conditions in the sequence program is not needed, the number of steps and the
sequence scan time can be reduced.
To execute an interrupt program, "EI" (Enable Interrupt) must be executed in the main program.
