Create programs for interrupt tasks 140 to 145, which are executed by the cor-
responding input interrupt. Always put an END(001) instruction at the last
address of the program.
This example shows how to execute interrupt task 140 when input CIO 0.04
goes ON.
1,2,3...
1. Connect an input device to input 0.04.
2. Use the CX-Programmer to set input 0 as an input interrupt in the PLC Set-
up.
3. Use the CX-Programmer to create the program to use for interrupt pro-
cessing and allocate the program to interrupt task 140.
4. Use the CX-Programmer to write MSKS(690) in the program.
