This safety-related bitwise Boolean function represents an AND logic with a safety-related signal and a standard signal as inputs to set a safety-related output signal. Using the EN_OUT function, the enable principle can be realized.
NOTE:
The Safety Logic Controller has access to all safety-related I/Os and is exclusively able to set safety-related outputs. This can be carried out directly or in conjunction with a standard signal of the standard controller program (enable principle).
Programming the enable principle is only allowed using the EN_OUT function without negations or any further signal processing.
WARNING
UNINTENDED EQUIPMENT 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.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
