Inquiring Coupling State and Coupling Number via Variables

Via variables in the NC program the current coupling state and the current or last active coupling group can be accessed. The following axis-group-related variables are introduced for this purpose:

Inquiring the current or last active coupling group:

V.G.AX_LINK.NR 

Inquiring the current coupling state:

V.G.AX_LINK.ACTIVE 

These variables only allow read access. A write operation leads to an error message and to abortion of the decoding process.
