3.9 Safety-related input/output signals (SGE/SGA)

The safety-relevant input and output signals (SGEs and SGAs) are signals that
are sent to or received by the system via two channels using:

•

Separate NCK and PLC I/Os

Fig. 3-25

SGE/SGA via separate PLC and NCK I/Os

•

or via PROFIBUS with PROFIsafe protocol and S7 fail-safe modules

Fig. 3-26

SGE/SGA via PROFIBUS with PROFIsafe protocol

Using these signals, the following can be requested or signaled in each
monitoring channel and for each axis/spindle with safety technology:

Safety functions can be selected and de-selected

Speed limit values can be selected and changed-over

Position limit values can be selected and changed-over

Feedback of status signals relating to safe operation

Cam signals can be output

Processing in two channels for SGEs and SGAs

Processing in the NCK monitoring channel
