How to decode the control information into single boolean control signals:
1. Go to the I/O level in the FB editor and connect the wControl output of the LS_SMInterface
system block with one of the free inputs wFreeIn1 ... wFreeIn4 of the application block.
• In the following example, the wControl output is connected with the free wFreeIn3 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, which is an output
on this level, with the wControl input of the L_SMControlDecoder_1 function block.
• The free inputs wFreeIn1 ... wFreeIn4 are outputs on the application level.
The L_SMControlDecoder_1 function block decodes the control signal assigned to the
wControl input into single boolean control signals for further use in the FB interconnection.
