    4. Modbus and Modbus TCP Modbus is a serial communication protocol that allows a wide variety of instruments to be connected to a common data collection network. Modbus/TCP is a variant of the Modbus communication protocol that allows devices to communicate over a TCP/IP. With the support of the Modbus TCP protocol, the OME-ET-7000/OME-PET-7000 series module can communicate with PC-based applications, such as SCADA (Supervisor Control And Data Acquisition) and HMI programs.

    4.1. Modbus TCP/IP Interface The Modbus/TCP interface is attached to the TCP/IP stack that is implemented within the OME-ET-7000/OME-PET-7000 module, and will listen to all communications that come in on Modbus/TCP registered Port 502. The Modbus/TCP client uses the standard TCP method for communicating with the OME-ET-7000/OME-PET-7000 module.

  • Page 95: Protocol Description

    4.2. Protocol Description The Modbus protocol defines a simple protocol data unit independent of the underlying communication layers. The mapping of Modbus protocol on network can introduce some additional fields on the application data unit. Modbus/TCP Application Data Unit Function MBAP Header Data Code...
  • Page 96 Function Code The function code field of a Modbus data unit is coded in one byte. Valid codes are in the range of 1 ... 255 decimal (the range 128 - 255 is reserved and used or exception responses). When a Modbus request is sent from a Modbus Client to a Server device the function code field tells the Server what kind of action to perform.
  • Page 97 Response If no error occurs related to the Modbus function requested in a properly received Modbus PDU (Protocol Data Unit) the data field of a Modbus response from a server to a client contains the data requested. If an error related to the Modbus function requested occurs, the field contains an exception code that the server application can use to determine the next action to be taken.

  • Page 98: Data Encoding

    4.3. Data Encoding Modbus uses a “big-endian” representation for address and data items. This means that when a numerical quantity larger than single byte is transmitted, the most significant byte (MSB, also called the high-order byte) is send first. The following sub-topics describe the different byte of encoding and show how the data is encoded as it is within the Modbus/TCP packet.

  • Page 99: Data Model

    4.4. Data Model Modbus bases its data model on a series of tables that have individual characteristics. The four primary tables are: Primary table Data type Type of access Discrete Input Single bit Read-Only Coils Single bit Read-Write Input Registers 16-bits word Read-Only Holding Registers...
