  • Page 12: Understanding Modbus Gateways

    Networks have become increasingly vital for industrial automation applications. Many control devices today do not have a network port and can only communicate with a dedicated local PC or control panel. Advantech’s revolutionary network-enabling technology is now allowing control devices with serial ports to connect to the Ethernet and share networks quickly and cost-effectively.
  • Page 13 data to be sent, and an error-checking field. The slave’s response message, which is also constructed using Modbus protocol, contains fields confirming the action taken, any data to be returned, and an error-checking field. If an error occurred in receipt of the message, or if the slave is unable to perform the requested action, the slave will construct an error message and send it as its response.

    2.1.2 Modbus RTU The Modbus/RTU protocol defines how a “master” device polls one or more “slave” devices to read and write data in real-time over RS-232, RS-422, or RS-485 serial data communication. When using RTU mode, each 8-bit byte in a message contains two 4-bit hexadecimal characters.
