18.1.161 L_SMStateDecoder_1
The integrated safety system transmits the status of safety functions to the application via the bit

individual boolean status signals for further use in the function block interconnection.
• The functionality of this FB corresponds to a converter "WORDBOOL", but the outputs of this
FB are named according to their meaning.
