LPCauseInter
Parameter Data type HSC mode User program access
HSCSTS.LPCauseInter BOOL 2...9 read/write
The Low Preset Interrupt status bit sets (1) when the HSC accumulator reaches
the low preset value and the HSC interrupt is triggered. This bit can be used in the
control program to identify that the low preset condition caused the HSC
interrupt. If the control program needs to perform any specific control action
based on the low preset, this bit is used as conditional logic.
This bit can be cleared (0) by the control program and is also cleared by the HSC
sub-system whenever these conditions are detected:
• High Preset Interrupt occurs
• Underflow Interrupt occurs
• Overflow Interrupt occurs
PlsPosition
Parameter Data type HSC mode User program access
HSCSTS.PLSPosition UINT 0...9 read only
When the HSC is in Counting mode, and PLS is enabled, this parameter indicates
which PLS element is used for the current HSC configuration.
