New PV Setting in NV and NV+1
Ladder Program
Examples
Example 1: High-speed
Counter (Linear Mode)
In this example, high-speed counter 0 operates in linear mode and starts
interrupt task 10 when the PV reaches 30,000 (0000 7530 hex).
1,2,3...
1.
Set high-speed counter 0 in the PLC Setup’s Built-in Input Tab.
2.
Set the target-value comparison table in words D10000 to D10003.
3.
Create the program for interrupt task 10. Always put an END(001) instruc-
tion at the program’s last address.
