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.
