  • Page 246 Chapter 10. CPL/TCP Communication Function ● Definitions of data in the data link layer The following list gives definitions of the data in the data link layer. Number of Item Character code Meaning characters Start of message Station address 0 to 7FH are expressed as For identification of hexadecimal character codes.
  • Page 247 Chapter 10. CPL/TCP Communication Function ● Checksum This value is for checking whether the message content was normally received without change due to some error (e.g., electrical noise). The checksum is expressed as two hexadecimal characters. • How to calculate the checksum (1) Add the character codes in the message from STX through ETX in single byte units.

  • Page 256: Numerical Representation In The Application Layer

    Chapter 10. CPL/TCP Communication Function 10 - 5 Numerical Representation in the Application Layer The numeric values in the application layer include the data address, number of data items, and data values. Depending on the command, hexadecimal or decimal notation is used. The same method of notation method is shared by the instruction message and the response message.

  • Page 257: Decimal

    Chapter 10. CPL/TCP Communication Function ■ Decimal The decimal specifications are shown in the table below. In the data address, a capital letter W (57H) is added immediately after the decimal number. If the message does not follow the specifications, the module does not process the instruction message and instead returns an error response.

  • Page 258: End Codes

    Chapter 10. CPL/TCP Communication Function 10 - 6 End Codes The result of the application layer process for the instruction message can be understood from the end code of the response message. There are two levels of result other than “Normal. ” An “Error” occurs when nothing was processed, and a “Warning” occurs when there is a possibility that some kind of processing was done.

  • Page 260: Communication Process

    Chapter 11. Modbus/TCP Communication Function ■ Communication process Modbus TCP uses the TCP/IP socket interface for communication. The TCP/IP socket interface is used in different ways depending on the host device, but this section will explain the method for an ordinary computer. (1) A TCP/IP socket connection is established from the host device (master station) to one unit (slave station).
