Changing the PV of a High-speed Counter
In this example, high-speed counter 0 operates in linear mode and starts interrupt task 10 when the
PV reaches
3
0,000 (0000 75
3
0 hex) and starts interrupt task 11 when the PV reaches 20,000 (0000
4E20 hex).
1
Set high-speed counter 0 in the PLC Setup's Built-in Input Tab.
2
Set the target-value comparison table in words D1000 to D1006.
3
Create the programs for interrupt tasks 10 and 11.
