BICO: Full parameter name/Abbreviated name
The following abbreviations can appear in front of the BICO parameter name:
CU/PM variants
Indicates for which Control Units (CU) and/or Power Modules (PM) the parameter is valid. If no
CU or PM is listed, then the parameter is valid for all variants.
The following information relating to "CU" and "PM" can be displayed under the parameter
number:
• BI: Binector Input
This parameter is used for selecting the source of a digital signal.
• BO: Binector Output
This parameter is available as a digital signal for interconnection with other
parameters.
• CI: Connector Input Connector Input)
This parameter selects the source of an "analog" signal.
• CO: Connector Output
This parameter is available as an "analog" signal for interconnection with other
parameters.
• CO/BO: Connector/Binector Output
This parameter is available as an "analog" and digital signal for interconnection
with other parameters.
Note
A BICO input (BI/CI) cannot be interconnected with just any BICO output (BO/CO, signal
source).
When interconnecting a BICO input using the commissioning software, only the corresponding
possible signal sources are listed.
Function diagrams 1020 ... 1030 explain the symbols for BICO parameters and how to deal
with BICO technology.
