Connection Examples

Warning against personal and property damage!
The use of the connection examples described in this section alone is not
enough to execute the safety function according to the SIL, Cat./PL determined
from the risk analysis. In connection with safe devices, sensors and actuators,
additional measures may be necessary to ensure the safety function.
This includes, for example, the appropriate wiring and parameterization of digital
inputs and outputs, as well as measures to exclude unforeseeable errors.
More information is available in the user manuals of the safe devices used.
This section generally describes possible applications, in which the functions of
the F I/O module for implementation of a safety function are used.
For the digital inputs of the F I/O module, you can use the WAGO
parameterization tool during individual parameterization to select the "Standard"
or "Rotary table" operating mode. For more information, read the section
"Commissioning" > ... > "Parameterization of the F I/O module with the WAGO
Parameterization Tool".
Use application notes from WAGO
An overview for using F I/O module in combination with a safe PLC is
summarized in an application note. This application note is available on the
Internet at

Connection Examples for Digital Inputs

If you have set the Operating Mode parameter of the F I/O module to "Standard"
using the WAGO parameterization tool, you can operate the inputs of the
F I/O module single- or two-channel.
Connection examples are further examined below.
Ensure protected installation of signal lines when Short Circuit Test is set
to "Deactivated"!
If you have set the Short Circuit Test parameter of an input to "Deactivated," the
signal lines must be installed with protection between the lines themselves and
between the sensors and inputs according to IEC 60204-1 or ISO 13849-2 (e.g.,
as separate sheathed lines or in separate cable ducts), since external short
circuits cannot be detected.
