XPS Unified Programmer’s Manual
7.2.1.156 PositionerCompensatedFastPCOSet
Name
PositionerCompensatedFastPCOSet – Calculates a set of evenly spaced firing
positions to the controller memory.
Input tests
- Refer to section 7.1: “Input Tests Common to all XPS Functions”.
- Checks Start <Stop, Step >0, and (Stop – Start) <Step: (-17)
- Checks the positioner name: (-18)
- Checks if CIEFAST compensated PCO pulses generation is enabled: (-121)
- Checks data number NData = floor(Stop - Start) / Step + 1, if NData >1000000:
(-122)
Description
This function calculates a set of evenly spaced firing positions to the controller memory.
Parameters:
• Start: Relative offset where first PCO trigger is generated. Start must be less than
Stop.
• Stop: Relative offset where last PCO pulses can be generated.
• Step: Distance between two consecutive pulses. Step must be positive.
This function will create a table of points that has as first point Start value and last point
Stop value:
Index = 0
Start
Index = 1
Start + Step
Index = 2
Start + 2 * Step
Index = 3
Start + 3 * Step
Index = 4
Start + 4 * Step
Index = …
…
Index = N
Start + N * Step
Example:
Send PositionerCompensatedFastPCOSet(XY.X, 0, 10, 1) will generate points table
below:
Index = 0
0
Index = 1

Index = 2

Index = …
…
Index = 10
