Binectors, BI: Binector input, BO: Binector output
A binector is a unitless digital (binary) signal that can assume a value of 0 or 1.
Binectors are subdivided into binector inputs (signal sink) and binector outputs (signal
source).

Connectors, CI: Connector input, CO: Connector output
A connector is a digital signal, e.g. in the 32-bit format. It can be used to emulate words (16
bits), double words (32 bits), or analog signals.
Connectors are subdivided into connector inputs (signal sink) and connector outputs (signal

Multiple connections
Several interconnections can be set simultaneously for a parameter, which, however, for
reasons of space, cannot be displayed in the interconnections field. Clicking on the icon
next to the interconnection field opens a list, which shows all of the active interconnections of
the parameter.
