Error output

Output for error message.

Data type: BOOL

Every error message (Error = TRUE) causes the enable signal at the S_AntivalentOut output to switch to SAFEFALSE and retain this state. The error state (Error = TRUE) can only be exited if there is a valid signal combination at the inputs.

WARNING
Unintended machine operation
  • Make certain that appropriate procedures and measures have been established to help avoid hazardous situations in the event of an error message or after the function block has been reset.
  • Ensure that no other persons can access the zone of operation when removing an error.
  • Use appropriate safety interlocks where personnel and/or equipment hazards exist.

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

ValueDescription
TRUEThe function block has detected an error. The enable signal at the S_AntivalentOut output switches to SAFEFALSE.
FALSEThe function block is either inactive or has not detected an error.
