Interaction of the transducer blocks and the DI function block

The DI function block can be used to read all 8 PFCs, independent of the DO function blocks. To this end,
he parameter "CHANNEL" has to be assigned the value 5. This establishes a connection to the transducer
blocks 1 to 4, which can be used to read out the PFC sensor values of the channels 1 to 4. These values
are then assigned to the respective bits of the parameter value "FIELD_VAL_D" according to the following
table:
Bit
