Depending on the data type of the BICO input parameter (signal sink) and BICO output
parameter (signal source) the following combinations are possible when creating BICO
interconnections:
BICO input parameter
CI parameter BI parameter
BICO output parameter U32 / I16 U32 / I32 U32 / Float U32 / Bin

Scaling
Specification of the reference quantity with which the signal value will be converted
automatically.
Reference quantities, corresponding to 100 %, are required for the statement of physical
units as percentages. These reference quantities are entered in P2000 ... P2004.
In addition to P2000 ... P2004 the following normalizations are used:
● TEMP: 100 °C = 100 %
● PERCENT: 1.0 = 100 %
● 4000H: 4000 hex = 100 %
