2.3.1.5 Interconnection examples
... for decoding the status and control information of the drive-based safety system into single
boolean signals.

How to decode the status information into single boolean status signals:
1. Go to the I/O level in the FB editor and connect the wState output of the LS_SMInterface
system block with one of the free inputs wFreeIn1 ... wFreeIn4 of the application block.
• In the following example, the wState output is connected with the free wFreeIn1 input
of the LA_NCtrl application block on the I/O level.
• For a better overview, all other connections of the LA_NCtrl application block are not
shown here.
2. Go to the application level and connect the selected free input wFreeIn with the wState
input of the L_SMStateDecoder_1 function block.
• The free inputs wFreeIn1 ... wFreeIn4 are outputs on the application level.
The L_SMStateDecoder_1 function block decodes the status signal assigned to the wState
input into single boolean status signals for further use in the FB interconnection.
