Note
As a result of the two-channel structure – both in the NCK monitoring channel
as well as in the drive monitoring channel – SGEs and SGAs must be supplied
from the machinery construction OEM.
The actual signal state of the SGEs/SGAs is displayed using the "Service display"
menu. Information regarding Safety Integrated data with the associated axis
names and the axis number are displayed in the "Service SI" window.
Sensor/actuators are, for Safety Integrated, connected through PROFIBUS with
the PROFIsafe profile and I/O modules that are PROFIsafe-capable. Internal SGE/
SGA signals are accessed via the SPL (see Section 7.3).
Fig. 7-2
For instance, the following can be requested or signaled in each monitoring chan-
nel and for each/spindle with safety technology using SGE/SGA signals:
S Safety functions can be selected and de-selected
S Limit values can be selected and changed-over
S States relating to safety operation can be fed back
Features
S SGE and SGA signals are processed through two channels
S Processed in the NCK monitoring channel
S Processed in the drive monitoring channel
S Safety functions are selected/de-selected independent of the NC mode
S Differences in the active SGEs/SGAs in the monitoring channels are detected in
the crosswise data/result comparison
The access to SGE/SGA signals is described in Section 7.2 "Connecting I/O via
PROFIsafe" and Section 7.3 "Safe programmable logic (SPL)".
