The solenoid for releasing the door tumbler is controlled via a standard output of the AS-i
slave installed in the position switch (output bit 0, see "Digital I/O"; Q0.0 in this example).
The read back signal (normally closed contact) of the solenoid is the second fail-safe channel
of the AS-i slave (see Section 4.2.3 (Page 25), 1BA4 version). Since it is directly processed to a
fail-safe digital input bit (in this example l32.1, see below) with the first fail-safe channel in
the F-CM AS-i Safety ST module, the read-back signal of the solenoid is accessed via the
associated standard input bit of the AS-i slave installed in the position switch (input bit 0, see
"Digital I/O"; in this example I0.0).

The safe monitoring of the emergency stop command device is then configured as follows.
