Interface Signals For Sinumerik 840D Sl - Siemens SINUMERIK 840D sl Function Manual

Data descriptions
9.6 Interface signals
Note
The SGE/SGA in the drive monitoring channel are mapped in an area of the NC/PLC interface
(signals to/from the drive) and must be supplied in the PLC user program.
As a result of the two-channel structure of Safety Integrated, the machine manufacturer must
supply the SGE and SGA in both the NCK monitoring channel and the drive monitoring channel.
Unused SGE must be set to a defined state.
