Error output

Output for error message.

Data type: BOOL

Note
Additional measures, e.g., an additional function stop, can be taken to reduce the risk of an unintended start-up.

The error state (Error = TRUE) can only be exited if there is a positive signal edge at the Reset input. If the error state has been caused by a static TRUE signal at the Reset input, this must be switched to FALSE in order to leave the error state.

If the safety-related function is no longer requested (S_OpMode = SAFETRUE) before or during the rising signal edge at the Reset input (for resetting errors), this can signal to the system/machine that a request for the safety-related function is no longer present. This can lead to a risk, for example with the machine/system starting up immediately.

WARNING

Unintended start-up

Include in your risk analysis the impact of the reset by means of a positive signal edge at the Reset input.
Make certain that appropriate procedures and measures (according to applicable sector standards) have been established to help avoid hazardous situations when resetting.
Do not enter the zone of operation when resetting.
Ensure that no other persons can access the zone of operation when resetting.
Use appropriate safety interlocks where personnel and/or equipment hazards exist.

Note
The error state of the function block can only be exited if the cause of the error no longer exists.

Connection: If required, the signal can be transmitted externally for diagnostic purposes (via a global I/O variable or other functions/function blocks).

Value	Description
TRUE	The function block has detected an error.
FALSE	The function block is either inactive or has not detected an error.
