SIDOOR functions
4.4 Safety functions
Implementation
For the implementation of this interfacing variant, the emergency stop signal is integrated into
the redundant antivalent safety circuit. The emergency stop element itself is only routed to the
SIDOOR controller through 1 channel. It is combined via an internal enabling logic with a STOP
door command of the highest priority.
The OPEN (door OPEN) and CLOSE (door CLOSE) door commands can only become active if no
emergency stop signal is present. The emergency stop signal is integrated in a low-active
branch. This is taken into account in the internal enabling logic.
After an emergency stop, a door command can only be activated again after both door
commands have been inactive together.
The OPEN (door OPEN) and CLOSE (door CLOSE) door commands are read in at the inputs 4 or
3 with negative logic (low-active).
The emergency stop signal is only active in combination with the issuing of a door command via
the external OPEN (door OPEN) or CLOSE (door CLOSE) encoders.
All digital inputs available on the SIDOOR controller can be used for this application.

Information regarding PLd
This interface is only ensures according to PLd that the motor control is safely read in with the
drive commands OPEN (door OPEN) or CLOSE (door CLOSE) and the emergency stop signal
according to stop category 1. This does not affect the distinction between the OPEN (door OPEN)
and CLOSE (door CLOSE) door commands.
