- TCP/IP-TCP, TCP/IP-TCP Redundant: it is possible to enter several IP addresses/symbolic names separated by commas or semicolons.
Note: if a TCP/IP-TCP or TCP/IP-TCP Redundant line has all stations set to StOFF, the TCP connection will be closed. Thus it is possible to control TCP communication from the ESL script using a STSTAT tell command. File I/O: reading from a file is supported (line by line or the entire file at once according to the File Read Mode protocol parameter.
As an "Input file" parameter, a specific file (e.g. C:\temp\input.txt) or a mask (e.g. C:\temp\*.txt) can be specified.
As an "Archive" parameter, the following can be specified:value #DELETE# - the input file is deleted after reading the data
directory name - the input file is moved to the specified directory after reading the data
empty value - the input file is not manipulated after reading the data
For both the "Input file" and "Archive" parameters, the symbolic constant #APPDIR# can be used to indicate the application directory (e.g. "#APPDIR#\input.txt").

| 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. | - | 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 the parameter Read Wait Timeout. | sec.mss | 1.000 | ||||||
| Character encoding | The method for text encoding/decoding for writing/reading. Implemented are:
Note: ISO_8859_1 mode is suitable for the transmission of 8-bit ASCII characters and implementation of binary protocols. | - | ISO_8859_1 | ||||||
| Read Size | Maximum size (in bytes) of input data. Longer data will be published in several chunks. | - | 1024 | ||||||
| File Read Mode | Method of reading data from a file:
| - | Read one row | ||||||
| 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 |

- The input I/O tag has an address IN.
Note: on redundant lines an I/O tag with address IN receives values read from any line (primary/secondary), eventually from any system (A/B). - on line-redundant lines (Serial Line Redundant, SerialOverUDP Line Redundant, TCP/IP-TCP Redundant) it is possible to configure I/O tags with addresses IN_A and IN_B to distinguish inputs from primary/secondary line
- on system-redundant lines (Serial System&Line Redundant, SerialOverUDP System&Line Redundant) it is possible to configure I/O tags with addresses IN_A, IN_B, IN_C, IN_D to distinguish inputs from primary/secondary line of system A/B
