Handling BICO technology
Binector:
r0723.15
Connectors are "analog signals" that can be freely interconnected (e.g. percentage variables, speeds or torques).
Connector:
r0723
Connectors are also "CO:" display parameters (CO = Connector Output).
Parameterization:
At the signal destination, the required binector or connector is selected using appropriate parameters:
"BI:" parameter for binectors (BI = Binector Input)
or
"CI:" parameter for connectors (CI = Connector Input)
Example:
The main setpoint for the speed controller (CI: p1070) should be received from the output of the motorized potentiometer
(CO: r1050) and the "jog" command (BI: p1055) from digital input DI0 (BO: r0722.0, Terminal 5 (Kl.5)) on the CU230.

Parameterizing steps:
Terminal 5 (Kl.5) acts as "Jog bit 0".
1 p1055[0] = 722.0
The output of the motorized potentiometer acts as main setpoint for the speed controller.
