7.2.1.164 PositionerCompensatedPCOSet
Name
PositionerCompensatedPCOSet – 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, Distance > 0, Width > 0, Width < Distance, Width < Stop-Start:
(-17)
- Checks the positioner name: (-18)
- Checks the position encoder (“AquadB” or “AnalogInterpolated”): (-24)
- Checks the CIE board supports this function: (-115)
- Checks CIE08CompensatedPCOMode = Enabled (system.ini): (-121)
- Checks data number NData = integer((Stop-Start)/Distance) + 1, if NData
>1000000: (-122)
Description
This function calculates a set of evenly spaced firing positions to the controller memory.
Parameters :
• Start: Relative distance to the start position where PCO pulses start.
• Stop: Relative distance to the start position where PCO pulses stop.
• Distance: Step of pulses (distance between two consecutive pulses)
• Width: Width of the pulse enable signal at the firing positions.
Example: Send PositionerCompensatedPCOSet (XY.X, 0, 3, 1, 0.1)
NOTE
Start and Stop are the offset values relative to the scanning positioner start
position that is defined in the PositionerCompensatedPCOPrepare().
The function works only when the CIE08 compensated PCO mode configuration is
enabled (system.ini: CIE08CompensatedPCOMode = Enabled).
This function can be used only with a position encoder (“AquadB” or
“AnalogInterpolated”), otherwise (-24) error is returned.
Prototype
int PositionerCompensatedPCOSet (int SocketID, char PositionerName[250] , double
Start, double Stop, double Distance, double Width)
Input parameters
SocketID int Socket identifier gets by the
“TCP_ConnectToServer” function
PositionerName char * Positioner name
Start double Start position (units)
Stop double Stop position (units)
Distance double Distance between two consecutive pulses (units)
Width double Width of pulse enable signal (units)
