A531 A531.00 High-speed
Counter 0
Reset Bit
When the reset method is set to phase-Z signal + soft-
ware reset, the corresponding high-speed counter's PV
will be reset if the phase-Z signal is received while this
bit is ON.
When the reset method is set to a software reset, the
corresponding high-speed counter's PV will be reset in
the cycle when one of these bits is turned ON.

Gate Bit
When one of these bits is turned ON, pulse inputs are
not counted and the PV of the corresponding high-
speed counter will not be changed.
When you turn OFF the bit, counting will be started
again and the PV of the high-speed counter will be
updated. If the reset method is set to phase-Z signal +
software reset and the corresponding High-speed
Counter Reset Bit (A531.00 to A531.03) is ON, then the
Gate Bit is not valid.

A532 --- Interrupt
Counter 0
Counter Set
Value
This word is used for an input interrupt in counter mode.
Set the count until the interrupt task is executed. When
interrupt counter 0 counts the number of pulses set
here, interrupt task 140 will be executed.

Value
This word is used for an input interrupt in counter mode.
Set the count until the interrupt task is executed. When
interrupt counter 1 counts the number of pulses set
here, interrupt task 141 will be executed.

Value
This word is used for an input interrupt in counter mode.
Set the count until the interrupt task is executed. When
interrupt counter 2 counts the number of pulses set
here, interrupt task 142 will be executed.

Counter 3
Counter Set
Value
This word is used for an input interrupt in counter mode.
Set the count until the interrupt task is executed. When
interrupt counter 3 counts the number of pulses set
here, interrupt task 143 will be executed.

Counter 0
Counter
Present
Value
Contain the PVs of the interrupt counters for input inter-
rupts in counter mode. In incremental mode, the count
is incremented one count at a time until it matches the
counter set value, at which time it returns to 0. In decre-
mental mode, the count is decremented one count at a
time from the set value until it reaches 0, at which time
it returns to the set value.
