  • Page 9: Glossary Of Modbus Tcp/Ip Terms

    Glossary of MODBUS TCP/IP terms MODBUS TCP/IP, like many other networking systems, has a set of unique terminology. Table below contains a few of the technical terms used in this guide to describe the MODBUS TCP/IP interface. They are listed in alphabetical order. Application Data Unit, it is the data frame of the MODBUS protocol.
  • Page 10 Valid codes are in the range of 1 ... 255 decimal (the range 128 – 255 is reserved and used for exception responses). Function code "0" is not valid. Lika encoders only implement public function codes. Refer to page 41.
  • Page 11 IEEE 1588 This standard defines a protocol enabling synchronisation of clocks in distributed networked devices (e.g. connected via Ethernet). Input register In the MODBUS data model, an Input register is the input data. An Input register has a 16-bit quantity, is provided by an I/O system, and allows read-only access.
  • Page 12 message to follow. Unit Identifier: 1 byte set by the Client and echoed by • the Server for identification of a remote slave connected on a serial line or on other buses. Refer to page 38. Media Access Control One of the sub-layers of the Data Link Layer that controls who gets access to the medium to send a message.
  • Page 13 packet inside the same node. Port numbers are divided between well-known port numbers (0-1023), registered user port numbers (1024-49151) and private-dynamic port numbers (49152-65535). For TCP, port number 0 is reserved and cannot be used. Ports allow TCP/IP to multiplex and demultiplex a sequence if IP datagrams that need to go to many different (simultaneous) application processes.
  • Page 14 and passengers. The data is actually transported by protocols. This is comparable to cars and commercial vehicles transporting passengers and goods on the highway. Tasks handled by the basic Transmission Control Protocol (TCP) and Internet Protocol (IP) (abbreviated to TCP/IP): 1.
