UFCauseInter BOOL 2...9 read/write Underflow caused a HSC. interrupt.
HPCauseInter BOOL 0...9 read/write High preset reached, causing a HSC interrupt.
LPCauseInter BOOL 2...9 read/write Low Preset reached, causing a HSC interrupt.
PlsPosition UINT 0...9 read only Position of the Programmable Limit Switch (PLS).
ErrorCode UINT 0...9 read/write Displays the error codes detected by the HSC sub-system.
Accumulator DINT
read/write Actual accumulator reading.
HP DINT
read only Last high preset setting.
LP DINT
read only Last low preset setting.
HPOutput UDINT

HSCSTSInfo parameter details
HSCSTSInfo (data type HSCSTS) parameters are used to determine the status of
the High-Speed Counter.
CountEnable
Parameter Data type HSC mode User program access
HSCSTS.CountEnable BOOL 0...9 read only
Indicates the status of the High-Speed Counter, whether counting is enabled (1)
or disabled (0, default).
ErrorDetected
Parameter Data type HSC mode User program access
HSCSTS.ErrorDetected BOOL 0...9 read/write
Detects if an error is present in the HSC sub-system. Configuration errors are the
most common types of error represented by the ErrorDetectedr. When the bit is
set (1), look at the specific error code in parameter HSCSTS.ErrorCode, which is
maintained by the controller. You can clear the ErrorDetected bit when necessary.
