3.2 Analog Outputs
The remote I/O is equipped with 4 analog outputs. These outputs are not safety-related, but all
together they can be shut down safely thanks to the configuration in the user program.
To achieve SIL 3, the output values must be read back via safety-related analog inputs and
evaluated in the user program. Reactions to incorrect output values must also be specified in
the user program.
NOTE
The analog outputs may only be used as safety-related outputs, if the output values are
read back to safety-related analog inputs and evaluated in the user program.
To configure the safe reaction, set the 4
Channel Used [BOOL] ->
system parameters to FALSE
(SILworX) or the 4
AO[1..4].Used
system signals to FALSE (ELOP II Factory). This appears
internal safety switches, ensuring that no output signal is output.
Alternatively, the safety reaction can be triggered using the
Emergency Stop
system variable.

The analog outputs are designed to retain the metrological accuracy for 10 years. A proof test
must be performed every 10 years.
