6.2 Execution Example of Interrupt Function

6.2.1 External Interrupt Input

 Overview
• The following figure shows the example that the output (Y160) from the 32-point output unit
is output at a high speed by the processing of an interrupt program when inputting the
external input (INT0) of the multi I/O unit (X108) in the state that the interlock input (X140) is
input to the 32-point input unit.
• In the normal processing that does not use the interrupt processing, it is reflected by the
scan time from an input to the signal output. However, when performing the interrupt
processing, the input status is reflected to the output with a slight delay that is not influenced
by the scan time.
0 V (24 V DC)
 Configuration
• Allocate an interrupt input to the input (X108) on the "Multi I/O Unit Setting" dialog box.
• Allocate "Interrupt terminal input (OFF -> ON)" as an interrupt occurrence condition.
