High-speed Counter PV Contains the PV of the high-speed counter.
High-speed Range 1 These flags indicate whether the PV is within the
Counter Range specified ranges when the high-speed counter is

High-speed Counter Com- This flag indicates whether a comparison operation
parison In-progress Flag is being executed for the high-speed counter.
OFF: Stopped.
ON: Being executed.
High-speed Counter Over- This flag indicates when an overflow or underflow
flow/Underflow Flag has occurred in the high-speed counter PV. (Used
with the linear mode counting range only.)
OFF: Normal
ON: Overflow or underflow
High-speed Counter This flag indicates whether the high-speed counter
Count Direction is currently being incremented or decremented. The
counter PV for the current cycle is compared with
the PLC in last cycle to determine the direction.
OFF: Decrementing
ON: Incrementing
High-speed Counter When the reset method is set to Phase-Z signal +
Reset Bit Software 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 this bit goes ON.
High-speed Counter Gate When a counter's Gate Bit is ON, the counter's PV
Bit will not be changed even if pulse inputs are received
for the counter.
When the bit is turned OFF again, counting will
restart and the high-speed counter's PV will be
updated.
When the reset method is set to Phase-Z signal +
Software reset, the Gate Bit is disabled while the
corresponding Reset Bit is ON.
