102.6 Handwheel selected (for handwheel 1, 2 or 3)
Edge evaluation: no
Signal state 1 or The operator has selected the handwheel for the defined axis via the operator panel front (i.e.
edge change 0 → 1 activated). This information is made available by the basic PLC program at the HMI interface.
The basic PLC program sets the interface signal:
DB21, ... DBX12.0-12.2 ff (Activate handwheel)
for the defined axis to "1".
The associated axis is also displayed at the HMI interface:
DB10 DBX100.7 ff (machine axis)
and
DB10 DBB100 ff (axis number for handwheel 1).
As soon as the handwheel is active, the axis can be traversed in JOG mode with the handwheel
(DB21, ... DBX40.0-40.2 ff (Handwheel active).
Signal state 0 or The operator has disabled the handwheel for the defined axis via the operator panel front. This
edge change 1 → 0 information is made available by the basic PLC program at the HMI interface.
The basic PLC program can set the interface signal:
DB21, ... DBX12.0-12.2 ff (Activate handwheel)
for the defined axis to "0".

Edge evaluation: no
Signal state 1 or The operator has assigned an axis to the handwheel (1, 2, 3) directly on the operator panel front.
edge change 0 → 1 This axis is a machine axis.
For further information see IS "Axis number".
Signal state 0 or The operator has assigned an axis to the handwheel (1, 2, 3) directly on the operator panel front.
edge change 1 → 0 This axis is a geometry axis.
For further information see IS "Axis number".
