Connectors
A connector has a value (16 or 32 bit) that can include a normalized quantity (without
dimension) as well as a quantity with associated units. Connectors always refer to functions
and are sub-divided into connector inputs and connector outputs. Essentially it is the same
as for the binectors; the connector inputs are characterized by a "P" parameter (e.g. P0771
CI: AO (analog output)) while the connector outputs are always represented using an "r"
parameter (e.g. r0021 CO: Act. frequency).
Example
Associate parameter r0755 (Displays analog input) with an internal value (main frequency setpoint).
Thus interconnect the CO Parameter r0755 (scaled analog input) with CI parameter P1070 (main
setpoint).
Connector Output (CO) == > Connector Input (CI)
