Description:
You are using a input module with HART communication and place a channel driver block (e.g. CH_AI) in the CFC chart. The input parameter "VALUE" of the channel driver block in the CFC chart is interconnected to the icon for the input channel generated in the HW Config. When you save and compile with the option "Create module driver", the channel driver block is not interconnected automatically.

Remedy: 
The module drivers are interconnect automatically in the "HART" operating mode only if the HART field devices are also incorporated in HW Config.

Without HART Field Device the module drivers are interconnected only if the operating mode is set to 2-wire transducer or 4-wire transducer.
