8.6 Interface signals
General information
The safety--related input and output signals (SGE and SGA) are signals that are
sent to and received from the system through two channels.
Warning
!
A STOP F (displayed using Alarms 27001, 27101 and onwards or F01711) only
results in a subsequent STOP B/A response, if at least one of the safety--related
functions SBH, SG, SE, SN or n<n
the function "n < n
STOP B/A response.
This means that if "n < n
SBH, SG, SE or SN functions must be active or selected (e.g. by selecting a high
SG level).
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 SGEs must be set to a defined state.
