V = Variables
R = Reading functions
The VC12Hdr function calculate the posit of the axis according to the HIGH DATA RAPPRESENTATION scheme.
VC12Hdr (Axis,HdrType,Result)
Parameters:
| IN/OUT | VARIABLE TYPE | EXAMPLE NAME | DIM | |
|---|---|---|---|---|
| Asse | EANPOS, OOPOS3, COUNTER3, ABSCNT, CAMMING4, CAMMING3, ANPOS2 | ooX | Device that manages a count | |
| HdrType | GLOBAL CONST | 2 | B | HDR viewing type |
| Result | GLOBAL | return | L | Data value converted |
The HDR viewing allows to center the range of the units on the integer values. The value is calculated by means of the encoder, measure and pulse is approximated to the nearest unit.
0 - Hdr disable.
1 - Hdr enable, in the central band between two units (between 0→1 the band is [0.25, 0.75] ) is shown a count that oscillates between two values.
2 - Hdr enable
With X axis
Measure: 220
Pulse: 4096
Encoder: 62296
the Posit is 3345 calcolated as 62296/4096*220 = 3345.97.
The VH12Hdr function (x,2,Result) will put Result = 3346.
