Interrupt Functions

MSKS(690) Operands
Note
*Input interrupts 4 and 5 are not supported by CPU Units with 14 I/O Points.
Writing the Interrupt
Task’s Program
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.
Input Interrupt
Settings and
Operation
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.)
Settings
1,2,3...
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.
Operation
When execution condition W0.00 goes ON, MSKS(690) is executed to enable
operation of the input interrupt in counter mode.
