 Time chart
In the case of
normal
processing
The output delays by the scan time.
In the case of
interrupt
processing
The signal is output with a slight delay.
 Program example
• Describe the interrupt enable instruction before the ED instruction, and describe a program
to be executed by the interrupt processing after the ED instruction.
• The interrupt program number corresponding to the input (X108) is INTPG10.

(Note 1): The input (X140) corresponds to (X2:IN0) on the program, and the output (X160) corresponds to (S3: OT0).
(Note 2): For the unit which uses the direct input (IN) and direct output (OT), set "Exclude this unit from the target for
I/O refresh." in the I/O map.
