■Overhead time when executing the interrupt program
The overhead time when executing the interrupt program includes the one before executing the interrupt program and the
other when the interrupt program finished.
• Overhead time before executing the interrupt program
Interrupt factor
Internal timer interrupt (I28 to I31)
Inter-module synchronous interrupt (I44)
Multiple CPU synchronous interrupt (I45)
High-speed internal timer interrupt 2 (I48), high-speed internal
timer interrupt 1 (I49)
Interrupt from module (I0 to I15, I50 to I1023)
• Overhead time when finishing the interrupt program
Interrupt factor
Internal timer interrupt (I28 to I31)
Inter-module synchronous interrupt (I44)
Multiple CPU synchronous interrupt (I45)
High-speed internal timer interrupt 2 (I48), high-speed internal
timer interrupt 1 (I49)
Interrupt from module (I0 to I15, I50 to I1023)
