BICO example
BICO or the binary interconnection technology can help the user to connect internal function
and values to realize more customized features.
BICO functionality is a different, more flexible way of setting and combining input and output
functions. It can be used in most cases in conjunction with the simple, access level 2
settings.
The BICO system allows complex functions to be programmed. Boolean and mathematical
relationships can be set up between inputs (digital, analog, serial etc.) and outputs
(converter current, frequency, analog output, digital outputs, etc.).
The default parameter that a BI or CI parameter is connected to is shown in the Factory
default column of the parameter list.
