9.3.3 Drives of Control Unit 2: Additional BICO interconnection
The infeed can be connected with a Control Unit via DRIVE CliQ. As Control_Unit_1 is
connected to the infeed, there is no possibility for the drives (drives_6..._9) controlled by
Control_Unit_2 to undertake a BICO connection of drive parameter "p864, BI: Infeed
operation" on the infeed signal "r863: Bit0, Infeed operation":
● Drive: p864, BI: BI: Infeed operation
● Infeed: r863: Bit0, Infeed operation
General procedure
In order to use the infeed signal for the drives controlled by Control_Unit_2, it must be
transferred via an external interconnection from an output terminal of Control_Unit_1 to an
input terminal of Control_Unit_2.
Implementation
The following input/output terminals of the control units are used as an example for the
following description:
● Control_Unit_1: p738, BI: CU signal source for terminal DI/DO 8 (X122.7)
● Control_Unit_2: r722: Bit0. CO/BO: CU digital inputs, status: :DI 0 (X122.1)
Perform the following actions to interconnect the drive parameters with the infeed signal:
1. Connect via BICO interconnection the infeed signal "r863: Bit0, Infeed operation", Project
> Drive unit_Adr10 > Infeeds > Infeed > Diagnosis > Connections > Tab "BO/CO" >
Signal: "r863: Bit0, Infeed operation" with the parameter for the output terminal (X122.7)
of the Control_Unit_1 "p738, BI: CU signal source for terminal DI/DO 8"

2. Configure the bidirectional digital input/output: "DO 8" (X122.7) of Control_Unit_1 as
output:
– Project > Drive_Unit_Adr10 > Control_Unit_1 > Double-click: "Inputs/outputs" > Tab:
"Bidirectional digital inputs/outputs" > DO 8 or X122.7 = output
