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.
