Function descriptions

NOTE
The converter functions available can be found in the function diagrams (block diagrams) in
Section 8.
Section 9 is not intended to be a complete description of these functions, but is aimed at
explaining in more detail individual features which could not be shown graphically in sufficient
detail in the figures, and to explain their applications using examples.
9.1

General explanations of terms and functionality

Function blocks
Although the illustrated function blocks have been implemented in digital form (as software modules),
the function diagrams can be "read" in a similar way to the circuit diagrams of analog equipment.
Configurability
The converter is characterized by the optional configurability of the function blocks provided. "Optional
configurability" means that the connections between individual function blocks can be selected by
means of parameters.
Connectors
All output variables and important computation quantities within the function blocks are available in the
form of "connectors" (e.g. for further processing as input signals to other function blocks). The
quantities accessed via connectors correspond to output signals or measuring points in an analog
circuit and are identified by their "connector number" (e.g. K0003 = connector 3).
Special cases: K0000 to K0008 are fixed values with signal levels corresponding to 0, 100, 200, -100, -
The internal numerical representation of connectors in the software is generally as follows:
100% corresponds to 4000 hexadecimal = 16384 decimal. The resolution is 0.006% (step change).
Connectors have a value range of -200% to +199.99%.
For a list of available connectors, please refer to Section 12.
Example: The data received via peer-to-peer 2 are available at connectors K6001 to K6005

200, 50, 150, -50 and -150%.
K0009 is assigned to different signal quantities. Which signal quantity it actually refers to
is dependent on the selector switch (parameter) at which connector number 9 is set. A
description can be found under the relevant parameter number in the Parameter List. If
the Parameter List or block diagram does not contain any reference to a special function
in relation to selection of connector K0009, then the selector switch (parameter)
concerned must not be set to "9".
