The line category determines basically the type of interface to a particular device. The 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 require the configuration of specific parameters depending on the configured line category. A typical example is an asynchronous communication line and settings of transmission parameters for individual line modes. A detailed description of these parameters and their interpretation you can find in topic communication protocols.

- 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 logical name of a particular line. The output file line_name.log is placed in the directory TRACE, 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 at the end of the file. Error logs are saved into this file automatically, although the "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 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 behavior of the communication channel. Line, in dependence on category, allows 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 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 which is opened after double-clicking the numerical level of a particular mode in the displayed table.

Only values in the column "Value" can be modified. The parameters, which have been changed, are highlighted (red color).
If you want to set the default parameter back, choose the parameter and click on the "Def" button placed below the list of protocols.
