EN_OUT

Type Function
Description Sets a safety-related output signal based on a standard and a safety-related input signal using AND logic.

This function can be used to implement the enable principle.
Notes The Safety PLC has access to all safety-related I/Os and is exclusively able to set safety-related outputs. This can be done directly or in conjunction with a standard signal of the standard controller program (enable principle). Programming the enable principle with the EN_OUT function is only allowed without negations or any further signal processing.

WARNING
Unintended machine operation
  • Verify that the EN_OUT function is used without negations or any further signal processing.
  • Verify that the influence of a standard signal via the EN_OUT function cannot result in an unintended or hazardous behavior of the entire system.
