Creating a function table

Identifying movements
If Safety Integrated is to be used for a machine in order to minimize the risk presented by
moving parts, then all of the possible hazardous movements should be carefully listed. Not
only do NC axes/spindles move, but also components such as the tool changer or chip
conveyor. The list might appear as follows:
Movements are performed by:
● Axes X, Y and Z and spindles
● Tool changer or turret
● Tool magazine and tool holder
● Chip conveyor
Why is the list so important?
The extended functions provide SOS and SLS for the monitoring of the numerically-controlled
axes/spindles. The other movements that are not numerically controlled can be safely shut
down even when the doors are open, either with safety relays or with contactors that are
controlled from four fail-safe outputs (F-DO 0.3) of the TM54F. These outputs can be
configured.
Creating a function table
The function table specifies which Safety Integrated function should be active for certain
machine states. A function table should be created before starting the configuration. The
function table is included later in the acceptance report and the last two columns are filled out
then.
Example of a function table:
