Chapter 14 High-Speed Counter (HSC) instructions
328 Rockwell Automation Publication 2080-RM001D-EN-E - February 2015
HP
Parameter Data type User program access
HSCSTS.HP DINT read only
The HSCSTS.HP is the upper setpoint (in counts) that defines when the HSC
sub-system generates an interrupt.
The data loaded into the high preset must be less than or equal to the data resident
in the overflow (HSCAPP.OFSetting) parameter or an HSC error is generated.
This is the latest high preset setting, which may be updated by PLS function from
the PLS data block.
LP
Parameter Data type HSC mode User program access
HSCSTS.LP DINT
read only
The HSCSTS.LP is the lower setpoint (in counts) that defines when the HSC
sub-system generates an interrupt.
The data loaded into the low preset must be greater than or equal to the data
resident in the underflow (HSCAPP.UFSetting) parameter or an HSC error is
generated. If the underflow and low preset values are negative numbers, the low
preset must be a number with a smaller absolute value.
This is the latest low preset setting, which may be updated by PLS function from
the PLS data block.
HPOutput
Parameter Data type User program access
HSCApp.HPOutput UDINT read/write
Defines the state (1 = ON or 0 = OFF) of the outputs on the controller when the
high preset is reached. For more information on how to directly turn outputs on
or off based on the high preset, see OutputMask.
You can configure the high output bit pattern during initial setup, or you can use
the HSC function block to load the new parameters while the controller is
operating.
