Editing of all objects in the process D2000 CNF is being performed in the configuration dialog box, a specific part of which is common for all editable objects and another part depends on the type of edited object.
Configuration The configuration dialog box of communication lines consists of several parts (tabs), which contains similar parameters. Display The display of particular tabs depends on the category of a particular communication line.
...
Selection of an object value type. For each communication line is the value type is - Li-Line.

Line The line category determines basically the type of interface to a particular device. The palette list of available communication protocols in the configuration of stations, which are the line children, varies according to the chosen line category. Most of the lines requires require configuration of specific parameters depending on adjusted the configured line category. A typical example is an asynchronous communication line and settings of transmission parameters for individual line modes. Detailed A detailed description of these parameters and their interpretation you can find in topic communication protocols.
...
This time represents the delay [ms], that is inserted between an incoming request for communication and its processing via the thread of the communication line. The parameter may be used to slow down (delay) communication or simulation.
...
Using this parameter allows to set setting the priority of the communication line thread. A high value represents a high priority and vice versa.
...
- None - no outputs.
- Screen - diagnostic outputs are displayed only on the screen (in the window of process D2000 KOM).
- Screen & Disk - diagnostic outputs are displayed on the screen and they are saved in LINE.LOG text file, where LINE is the logic logical name of a particular line. The output file line_name.log is placed in the directory TRACE, that which is a subdirectory of the application directory. This directory is created automatically and the maximum size of the file is 10 MB. The oldest logs are deleted, new diagnostic logs are stored on at the end of the file. Error logs are saved into this file automatically, although "Monitor & Disk" radio button is not enabled. Error logs are saved automatically, together with the time and date of their occurrence.
- Disk - diagnostic outputs are saved only into a file on disk (see "Monitor & Disk"). Error messages are displayed also on the screen.
...
The name of the tab depends on the communication protocol selected for the station. It contains special parameters of the communication protocol and they are described in the documentation of the respective communication protocol.

The Line modes tab is accessible only for the Serial line category in the configuration window. In modified form, these parameters can be defined also for the lines of "Serial Line Redundant", "Serial System&Line Redundant" and "Moxa IP Serial Library" categories.

Line modes
The table displays the parameters of individual modes of a particular communication line. These parameters are transferred into the communication process as parameters for the setting and behaviour behavior of the communication channel. Line, in dependence on category, allows to define defining several different sets of parameters for communication (up to 4). The choice of particular sets of parameters (mode 1, mode 2, mode 3 or mode 4) that is are used for the communication depends on the value of the Line mode spin button in the configuration dialog box of a Station object, that uses the communication line. This procedure enables the communication of stations, which communicate with the use of various parameters of the communication line (Baud rate, number of bits, etc.) via one physical line. Parameters of line modes are configured in the dialog box, that is opened after double-clicking the numerical level of a particular mode in the displayed table.

This tab contains a full list of protocol communication parameters. They influence and set communication of all stations on a communication line.
When you want to set some parameters you have to choose the communication protocol in the upper part of the tab.
If the protocol is not in the list it means that it has no line protocol parameters.
The list contains the following information:
- Parameter name
- Value
- Technical units and permitted range
- Default value
