Axis-specific interface (e.g. for V.A variables)

IndexGroup: IdxGrp = 0x122300 + Channel ID

Index offset of other axes: IdxOffs += 0x10000 * axis index

Example Channel 1, Axis 1: IdxGrp = 0x122301

IdxGrp	IdxOffs	Function	Description	Input	Output
0x122301	0x10004	Variable handle by name	Handle for access to the variable	STRING max. 255 characters	Handle (UNS32)
0x122301	0x10005	Read variable value by name	Read variable value by variable name	STRING max. 255 characters	BYTE[2048] variable length
0x122301	0x10006	Write variable value by name	Write variable value by variable name	BYTE[2048] variable length	-
0x122301	0x10007-0x10009	reserved	Reserved	-	-

Instance identifier

In the axis-specific interface, the variable names contain no instance identifier.

Example: V.A.ACT_POS

The axis-specific interface always supplies the variable value of the current axis currently assigned to this position. In case of axis exchange the variable value displayed therefore changes.
