Chapter 8 Use the High-Speed Counter and Programmable Limit Switch
This bit is maintained by the controller and is set when there is an HSC error.
This bit can be cleared by the user, if necessary.
The Count Up bit is used with all of the HSCs (modes 0…9). If the
HSCSTS.CountEnable bit is set, the Count Up bit is set (1). If the
HSCSTS.CountEnable is cleared, the Count Up bit is cleared (0).
The Count Down bit is used with the bidirectional counters (modes 2…9). If the
HSCSTS.CountEnable bit is set, the Count Down bit is set (1). If the
HSCSTS.CountEnable bit is clear, the Count Down bit is cleared (0).
The Mode Done status flag is set (1) by the HSC sub-system when the HSC is
configured for Mode 0 or Mode 1 behavior, and the accumulator counts up to
the High Preset.
The HSCSTS.OVF status flag is set (1) by the HSC sub-system whenever the
accumulated value (HSCSTS.Accumulator) has counted through the overflow
variable (HSCAPP.OFSetting).
This bit is transitional and is set by the HSC sub-system. It is up to the control
program to utilize, track if necessary, and clear (0) the overflow condition.
Overflow conditions do not generate a controller fault.
The Underflow status flag is set (1) by the HSC sub-system whenever the
accumulated value (HSCSTS.Accumulator) has counted through the underflow
variable (HSCAPP.UFSetting).
