*Input interrupts 2 and 3 are not supported by the Y CPU Units.
Create programs for interrupt tasks 140 to 147, 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 141 when 200 up-differenti-
ated pulses have been counted at input CIO 0.01. (The counter is an incre-
menting counter.)
1. Connect an input device to input 0.00.
2. Use the CX-Programmer to set input 0.01 as an input interrupt in the PLC
Setup.
3. Use the CX-Programmer to create the program to use for interrupt pro-
cessing and allocate the program to interrupt task 141.
4. Use the CX-Programmer to set a high-speed counter SV of 00C8 hex (200
decimal) in A533.
5. Use the CX-Programmer to write MSKS(690) in the program.
W0.00
(Execution condition)
@ MSKS(690)

@MSKS(690)

#0003
When execution condition W0.00 goes ON, MSKS(690) is executed to enable
operation of the input interrupt in counter mode.
