Configuration dialog box of communication lines consists of several parts (tabs), which contains similar parameters. Display of particular tabs depends on the category of particular communication line.

Line category determines basically the type of interface to particular device. The palette of available communication protocols in configuration of stations, which are the line children, varies according to the chosen line category. Most of the lines requires configuration of specific parameters depending on adjusted category. A typical example is an asynchronous communication line and settings of transmission parameters for individual line modes. Detailed description of these parameters and their interpretation you can find in topic communication protocols.

There are the following levels to trace the communication with the communication line:
- 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 name of particular line. The output file line_name.log is placed in the directory TRACE, that 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 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 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.

Line modes tab is accessible only for 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.

The table displays parameters of individual modes of particular communication line. These parameters are transferred into communication process as parameters for setting and behaviour of communication channel. Line, in dependence on category, allows to define 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 used for the communication depends on the value of 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 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 particular mode in the displayed table.
