What is Modbus TCP protocol for power energy meter?

Modbus TCP protocol has become a cornerstone in the realm of power energy meters, offering a standardized and efficient means of communication between devices in industrial and energy management systems. In this article, we will delve into the intricacies of Modbus TCP protocol, exploring its definition, features, and diverse applications in the context of power energy meters.

What is Modbus TCP Protocol?

Modbus TCP protocol is an open-source, widely used communication protocol that facilitates the exchange of information between devices connected on a TCP/IP network. Specifically designed for industrial automation and control systems, Modbus TCP allows seamless communication over Ethernet networks, making it particularly suitable for power energy meters deployed in various industrial settings.

MODBUS/TCP enables the MODBUS_RTU protocol to run on Ethernet. MODBUS TCP uses TCP/IP Ethernet to transmit MODBUS messages between sites. MODBUS TCP combines the Ethernet physical network and network standard TCP/IP as well as data with MODBUS as the application protocol standard. display method. MODBUS TCP communication packets are in Ethernet TCP/IP data packets. Unlike the traditional serial port method, MODBUS TCP inserts a standard MODBUS message into the TCP message and no longer carries a data checksum address.

Simply speaking, the ModbusQ TCP protocol is a variant of the Modbus protocol based on the TCP/P network. It encapsulates the Modbus protocol in the TCP/P protocol stack and uses Ethernet as the physical layer to connect devices through TCP. Communication.
