Error output
Output for error message.
Data type: BOOL
Every error message (Error = TRUE) causes the enable signal at the S_GuardLocked output to switch to SAFEFALSE and retain this state.
| 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 exit the error state.1
| 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. The enable signal at the S_GuardLocked output switches to SAFEFALSE. |
| FALSE | The function block is either inactive or has not detected an error. |
| 1 | Resetting the error by activating the reset button can cause the S_GuardLocked output to switch to SAFETRUE immediately (depending on the status of the other input signals). |
