Use Guard I/O modules in DeviceNet safety architectures as shown in
the figure.
The Guard I/O family is a set of I/O modules that when connected to
a DeviceNet safety network are suitable for applications up to SIL3, as
defined in the IEC 61508 standard, and Safety Category 4, as defined
in the EN 954-1 standard.

Software
Safety input devices such as emergency-stop switches and safety
output devices, such as safety contactors, can be connected to safety
I/O blocks. Standard devices, such as proximity switches,
pushbuttons, or lamps, can also be connected to safety I/O blocks.
Safety PLC controllers or safety network controllers control the safety
outputs. Safety PLC controllers, safety network controllers, or standard
PLC controllers can control the standard outputs.
The modules provide self-diagnostics to test the electronics within the
module. The safety outputs provide a pulse test feature for diagnosing
the external wiring of field actuators. Testing of input wiring is by
connecting the field input devices to one of the pulse test outputs
provided by the modules. Any pulse test outputs not used to test input
wiring can be used as a standard output. At least one of these
standard outputs is configurable with current monitoring to use it for
control and monitoring of a muting lamp.
