For simple emergency off applications without signal fault security, you can use a
digital input for your safety function.
You can connect the digital input via a switching element (e.g., an emergency off
switch) either to the associated clock output or to the field supply voltage U
directly. Alternatively, you can connect the semiconductor output of a sensor to
the digital input directly. For the single-channel use if a digital input, you must set
the Dual channel evaluation parameter to "no".
For more information about configuring the PROFIsafe I/O module, read section
"Commissioning" > ... > "Parameterization of the PROFIsafe I/O Module with
the WAGO Parameterization Tool".
If you do not connect the digital input via a switching element to the associated
clock output (e.g., semiconductor output), set the Short circuit test parameter to
"not active". Otherwise, the PROFIsafe I/O module detects a short circuit on the
input and outputs the "Short circuit" diagnostic message.
If you connect the digital input via the switching element to the associated clock
output and the PROFIsafe I/O module should monitor the signal line for short
circuits, you have to set the Short circuit test to "active".
If you connect a safe sensor without single fault security to a digital input, SIL2,
Cat. 3/PL d is achieved with these connections.
In both connections, errors in the mechanics and electrical system of the safe
sensor must be excluded. The B 10 values of the safe sensors must be available.
