18.1.160 L_SMControlDecoder_1
The integrated safety system transmits information on requested or active safety functions via the
bit-coded wControl control signal of the SB LS_SMInterface . This FB decodes the control signal into
individual boolean control signals for further use in the function block interconnection.
• Several safety functions can be requested/active at the same time.
• Which safety functions are supported depends on the safety module used or the available
safety option.
• The functionality of this FB corresponds to a converter "WORDBOOL", but the outputs of this
FB are named according to their meaning.


Note!
The application in the controller has to evaluate the wControl control signal and execute
the corresponding action. This action (e.g.braking to a standstill) has to be implemented
by a corresponding application interconnection, which has to be carried out by an
application engineer!
