Note
The parameters EN and ENO are only present in the graphical representation
(LAD or FBD). The block is started with EN = TRUE. If the function is completed
without errors, ENO = TRUE is set. To process these parameters, the compiler
uses the binary result BR.
The binary result BR is set to the signal state "1" if the block was terminated
without errors. If there was an error, the BR is set to "0".
