HSC Mode (HSCAPP.HSCMode)

Description Data Format
HSC Mode word (UINT)
The HSCMode variable sets the High-Speed Counter to one of 10 types of
operation. This integer value is configured through the programming device and
is accessible in the control program.
HSC Operating Modes
Mode Type
Number
0 Up Counter – The accumulator is immediately cleared (0) when it reaches the high
preset. A low preset cannot be defined in this mode.
1 Up Counter with external reset and hold – The accumulator is immediately cleared (0)
when it reaches the high preset. A low preset cannot be defined in this mode.
2 Counter with external direction
3 Counter with external direction, reset, and hold
4 Two input counter (up and down)
5 Two input counter (up and down) with external reset and hold
6 Quadrature counter (phased inputs A and B)
7 Quadrature counter (phased inputs A and B) with external reset and hold
8 Quadrature X4 counter (phased inputs A and B)
9 Quadrature X4 counter (phased inputs A and B) with external reset and hold
