Enhanced zero offset variables

Variable	Meaning	Read	Write
V.G.NP[j].ALL	Address 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	Address currently active zero offsets of all axes	yes	yes
V.G.NP_DEFAULT	Index of effective zero offset in initial state	yes	yes

Write access via the V.G.NP[j] and V.G.NP_DEFAULT variables remains effective until the next list interpretation (explicit request or start-up). By contrast, write accesses via V.G.NP_AKT are only effective on zero offsets currently stored in the decoder. When the NPV previously written via V.G.NP_AKT is re-selected, the original values from the list again become effective. The current data record must be saved to the list by assignment via V.G.NP[j].ALL to retain write access to V.G.NP_AKT after deselection.

Programing Example

Saving the currently active zero offset values:

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