MC_GroupReadActualPosition

This FB serves to read the current position of the axes group in the selected coordinate system.

This is an administrative FB as no motion command is generated.

BOOL

TRUE

Read current position of the axes group continuously.

CoordSystem

Selection of the coordinate system to be used:

WCS: World Coordinate System

MCS: Machine Coordinate System

ACS: Axes Coordinate System

PCS_1 ... PCS_16: Product Coordinate System (1 ... 16)

Name Data type	Value/meaning
Valid BOOL	TRUE	Valid values are applied to the FB outputs.
Busy BOOL	TRUE	Processing is running.
Error BOOL	TRUE	An error has occurred. For details see ErrorID .
ErrorID L_IE1P_Error	If Error = TRUE: Error number for the error that has occurred.
Position ARRAY [1..12] OF LREAL	Current position of the axes group: [1; 6] When ACS is selected: Position of the drive axes. When WCS , MCS or PCS are selected: Position of the TCP in the selected coordinate system. Index 7 ... 12 = axis positions of the optionally available auxiliary axes.
