3.1.2.3 BICO technology 
Using BICO technology (English: Binector Connector Technology), process data 
can be freely interconnected using the "standard" drive parameterization. In this 
case, all values which can be freely interconnected (e.g. frequency setpoint, 
frequency actual value, current actual value, etc.) can be defined as "Connectors" 
and all digital signals which can be freely interconnected (e.g. status of a digital 
input, ON/OFF, message function when a limit is violated etc.) can be defined as 
"Binectors". 
There are many input and output quantities as well as quantities within the closed-
loop control which can be interconnected in a drive unit. It is possible to adapt the 
drive to the various requirements using BICO technology. 
A binector is a digital (binary) signal without any units and which can either have 
the value 0 or 1. Binectors always refer to functions whereby they are sub-divided 
into binector inputs and binector outputs (refer to Fig. 3-4). In this case, the 
binector input is always designated using a "P" parameter with attribute "BI" (e.g.: 
P0731 BI: Function, digital output 1), while the binector output is always 
represented using an "r" parameter with attribute "BO" (e.g.: r0751 BO: ADC status 
word). 
As can be seen from the examples above, the binector parameters have the 
following abbreviations in front of the parameter names: 
¾ 
BI  Binector Input, signal receiver ("P" parameters) 
  →  The BI parameter can be interconnected with a binector output as source, by 
entering the parameter number of the binector output (BO parameter) as 
value in the BI parameter (e.g.: Interconnecting the "BO" parameter r0751 
with "BI" parameter P0731 →  P0731 = 751). 
¾ 
BO  Binector Output, signal source ("r" parameters) 
→  The BO parameter can be used as source for BI parameters. For the 
particular interconnection the BO parameter number must be entered into 
the BI parameter (e.g.: Interconnecting the "BO" parameter r0751 with "BI" 
parameter P0731 →  P0731 = 751).

Fig. 3-4  Binectors 
A connector is a value (16 or 32 bit), which can include a normalized quantity 
(without dimension) as well as also a quantity with associated units. Connectors 
always refer to functions whereby they are sub-divided into connector inputs and 
connector outputs (refer to Fig. 3-5). Essentially the same as the binectors, the 
connector inputs are characterized by a "P" parameter with attribute "CI"  (e.g.: 
P0771 CI: D/A converter); while the connector outputs are always represented 
using an "r" parameter with attribute "CO" (e.g.: r0021 CO: Smoothed output 
frequency).
