A520 00 to 15 Interrupt Counter 0
Counter SV
Used for interrupt input 0 in counter mode.
Sets the count value at which the interrupt task will start. Interrupt task
000 will start when interrupt counter 0 has counted this number of
pulses.
Setting range: 0000 to FFFF

A521 00 to 15 Interrupt Counter 1
Counter SV
Used for interrupt input 1 in counter mode.
Sets the count value at which the interrupt task will start. Interrupt task
001 will start when interrupt counter 1 has counted this number of
pulses.
Setting range: 0000 to FFFF
A522 00 to 15 Interrupt Counter 2
Counter SV
Used for interrupt input 2 in counter mode.
Sets the count value at which the interrupt task will start. Interrupt task
002 will start when interrupt counter 2 has counted this number of
pulses.
Setting range: 0000 to FFFF
A523 00 to 15 Interrupt Counter 3
Counter SV
Used for interrupt input 3 in counter mode.
Sets the count value at which the interrupt task will start. Interrupt task
003 will start when interrupt counter 3 has counted this number of
pulses.
