| Keyword | Full name | Description | Unit | Default value |

| TCP Server | Activates server mode on the TCP/IP-TCP line. In this mode, the D2000 KOM process listens to the client connection. After the client is connected, the D2000 KOM process communicates with it (i.e., it is a single-server implementation handling a single client). After the client is disconnected, the D2000 KOM process listens again.
In server mode, the entered server name is interpreted as the name/IP address of the interface on which the D2000 KOM process listens. It is also possible to enter symbolic names * resp. ALL (listening on all interfaces for IPv4 protocol), or [*] resp. [ALL] (listening on all IPv6 interfaces). | - | False |
| Read Wait Timeout | Waiting between individual data readouts from the communication. If no data was received during this period and previously some data was read, it will be published as a value of input I/O tag IN.
If some data was received during this period, it will be appended to a buffer, until a timeout occurs or the buffer becomes full (see a parameter Read Size). If a parameter Log Each Read is set to True, data will be published immediately regardless of the value of parameter Read Wait Timeout. | sec.mss | 1.000 |
| Character encoding | The method for text encoding/decoding for writing/reading. Implemented are: - UTF-8
- ISO_8859_1
- Windows_1250
- Windows_1251
- Windows_1252
- KZ_1048
Note: ISO_8859_1 mode is suitable for transmission of 8-bit ASCII characters and implementation of binary protocols.
Note: if invalid data is read (e.g. for UTF-8 encoding), the input I/O tag will be invalidated. | - | ISO_8859_1 |
| Read Size | Maximum size (in bytes) of input data. Longer data will be published in several chunks. | - | 1024 |
| Log Each Read | If this parameter is set to True, data will be published immediately regardless of the value of the parameter Read Wait Timeout. | - | False |
| Log Format | Format of data traces in log files: "0 - Hexa log" or "1 - Text log".
Setting the correct format helps to make a communication log file more readable depending on whether the specific protocol is text-oriented or binary by dumping the data in text or hexadecimal format. | - | 0 - Hexa log |
| Single Log | Setting this parameter to True will make all logs to be written to a single file on redundant lines.
Setting this parameter to False means that two log files will be created for the primary/secondary line (Serial Line Redundant, SerialOverUDP Line Redundant, TCP/IP-TCP Redundant), or four log files will be created for the primary/secondary line of the A/B system (Serial System&Line Redundant, SerialOverUDP System&Line Redundant). | - | False |
