PLC Function Blocks

The objects configured in the TwinCAT Building Automation Framework can also be used with the following function blocks from the PLC. Performance features that are not covered by the standard functions of the TwinCAT Building Automation Framework can thus be implemented with the help of these function blocks. The function blocks are contained in the PLC library TcBAFramework2.20.lib.

The function blocks are firmly bound to the respective type. This means, for example, that only one DALI lamp can be addressed with the function blockFB_BAFLampDALI(). An error message is returned if an attempt is made to address a standard lamp object or a DALI lamp for the security lighting.
