4.3.3 Signals from PLC
4.3.4 Signals from operator panel
Special cases, errors, ... An alarm that withdraws the IS "808D READY" (DB3100 DBX0.3), ensures
that the channel is no longer in the reset state.
In order to switch to another mode, a reset (DB1800 DBX0.7) must be
initiated.

DBX1.2
Active machine function REF
Signal(s) to PLC (HMI → PLC)
Edge evaluation: Yes Signal(s) updated: Cyclic
Signal state 1 or edge
change 0 → 1
The machine function REF is selected in the JOG mode
The signal state 1 is only present for one PLC cycle.
Signal state 0 The machine function REF is not selected.
Signal irrelevant for ... if JOG mode is not active.

Commissioning archive was read in
Edge evaluation: Signal(s) updated:
Meaning Is set, if a commissioning archive or a data class file tree was read in and is
present for one PLC cycle. The PLC system then deletes the signal.

Simulation active
Signal(s) from HMI → PLC
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The function – Simulation – has been selected from the operator interface.
Signal state 0 The function – Simulation – has not been selected from the operator
interface.
corresponding to ... if JOG mode is not active.

Switch over Machine/Work
Signal(s) from HMI → PLC
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The coordinate system is switched over from workpiece coordinate system
(Work) to machine coordinate system (Machine) or from Machine to Work.
After actuation, the signal is present for 1 PLC cycle.
Signal state 0 No effect.
