A connector has a value (16 or 32 bit), which 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).
As can be seen from the examples above, connector parameters have the following
abbreviations in front of the parameter names:
CI: Connector Input, signal sink ("P" parameters)
The CI parameter can be interconnected with a connector output as a source, by entering
the parameter number of the connector output (CO parameter) as a value in the CI
parameter.
CO: Connector Output, signal source
The CO parameter can be used as source for CI parameters. For a particular
interconnection, the CO parameter number must be entered in the CI parameter.
Example: Interconnecting the CO parameter r0021 with CI parameter P0771: → P0771 = 21
Further, there are "r" parameters where several binector outputs are combined in a word
(e.g. r0052 CO/BO: Status word 1). This feature reduces, on one hand, the number of
parameters and simplifies parameterization using the serial interface (data transfer). These
parameters are further characterized by the fact that they do not have any units and each bit
represents a digital (binary) signal.
As can be seen from the examples of parameters, these combined parameters have the
following abbreviation in front of the parameter names:
CO/BO: Connector Output/Binector Output, signal source ("r")
CO/BO parameters can be used as a source for CI parameters and BI parameters:
● In order to interconnect all of the CO/BO parameters, the parameter number must be
entered into the appropriate CI parameter (e.g. P2016[0] = 52).
● When interconnecting a single digital signal, in addition to the CO/BO parameter number,
the bit number must also be entered into the CI parameter (e.g. P0731 = 52.3)
