Enhanced Zero Offset Variables

V.G.NP[j].ALL

Addressing of all axes of a zero offset

yes

yes

V.G.NP_AKT.V[i]

Current (currently active) zero offset of an axis

yes

yes

V.G.NP_AKT.ALL

Addressing of the current (currently active) zero offsets of all axes

yes

yes

V.G.NP_DEFAULT

Zero offset that is effective in the initial state.

yes

yes

Write access via the V.G.NP[j] and V.G.NP_DEFAULT variables remain effective until the next interpretation of the list (explicit request or start-up). Write access via V.G.NP_AKT, in contrast, has only an effect on the zero offsets that are currently stored in the decoder. If a zero offset that has previously been written to via V.G.NP_AKT is selected again, its original value from the list becomes effective again. The current data record must be saved in the list by assigning via V.G.NP[j].ALL if the write access to V.G.NP_AKT shall be held beyond de-selection.

Programming example

Saving of the currently active zero offset values:

V.G.NP[12].ALL=V.G.NP_AKT.ALL
