Interrupt Counter
Counter SV
Used for an interrupt input in counter mode.
Sets the count value at which the interrupt task will start. The corre-
sponding interrupt task will start when the interrupt counter has
counted this number of pulses.
Read/Write
• Retained when power is
turned ON.
• Retained when opera-
tion starts.
Interrupt Counter
Counter PV
These words contain the interrupt counter PVs for interrupt inputs
operating in counter mode.
In increment mode, the counter PV starts incrementing from 0.
When the counter PV reaches the counter SV, the PV is automati-
cally reset to 0.
In decrement mode, the counter PV starts decrementing from the
counter SV. When the counter PV reaches the 0, the PV is automat-
ically reset to the SV.
Read/Write
• Retained when power is
turned ON.
• Cleared when operation
starts.
• Updated when interrupt
is generated.
