The signals can be subdivided into the following groups (see above):
● General signals
● Mode signals
●
Channel signals
● Axis / spindle signals
Notes on the PLC interface signal address representation
Currently, PLC interface signal addresses are represented by the V structure on the HMI while
the manual shows them by the DB structure.
See the following table for the relationship between the two representations.

NC start disable
Signal(s) from PLC → HMI
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The NC start disable prevents a part program from being started with the NC
start signal DB3200 DBX7.1 (NC start) == 1.
Signal state 0 The NC start disable is not active.
Special cases, errors, ... The start of a part program selected in the channel by part program command
START in another channel (program coordination) is not prevented by the
interface signal:
DB3200 DBX7.0 (NC start disable) == 1.
corresponding to ... IS "NC start"
Note for the reader
DB1600
DBX2000.1
Read-in disable
Signal(s) from PLC → HMI
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The main run reads in no more preprocessed part program blocks.
Note:
The signal is only active in the AUTOMATIC and MDI modes.
