The communication protocol specifies the type of station communication protocol. The set of protocols is continuously being extended by new ones. The documentation of individual protocols can be found here. The list of available protocols depends on the category of the line, which is the parent of the station, as well as on the scope of the D2000 licence.
Changing the communication protocol is only partially supported by the D2000 KOM process and may require a restart of this process to apply the changes properly. The recommended alternative (which does not require a restart) is to create a new line (with the correct category), new station(s) and migrate the I/O tags using XML export/XML Import (probably also changing their addresses due to the protocol change).
Line mode
The selection of one of four modes of the communication line. For lines of Serial, "Serial Line Redundant", "Serial System&Line Redundant" and "Moxa IP Serial Library" categories, it is possible to define several sets (up to 4) of serial communication parameters. The value of the Line mode parameter determines which of the sets will be used for communication with this station. This enables having stations with various communication baud rates, parities, etc., using the same physical line.
