Modbus TCP/IP is an Internet protocol. The fact that TCP/IP is the transport protocol of the Internet automatically means that Modbus TCP/IP can be used over the Internet. It was designed to reach this goal. In practical terms, this means that a Modbus TCP/IP device installed in Europe can be addressed over the Internet from anywhere in the world. The implications for an equipment vendor or an end-user are endless. Performing maintenance and repair on remote devices using a PC and browser reduces support costs and improves customer service. Logging onto a plant’s control system from home allows the maintenance engineer to maximize his plant’s uptime and reduces time in the field. Managing geographically distributed systems becomes easy using commercially available internet/intranet technologies.
