Key Components of Modbus TCP/IP: Client: This is the device initiating the communication, requesting data from other devices. Think of it as the customer placing an order. Server: This is the device responding to the client's requests, providing the requested data. This is analogous to the supplier fulfilling the order.
Siemens SIMATIC S7 PLC as Modbus TCP Server: A Quick Tutorial
Oct 16, 2024 · Step 2: Configure the IoT Gateway. Now, configure the IoT gateway as a Modbus client. In the gateway’s configuration interface: Set the IP address of the Modbus server (the Siemens PLC). Ensure the Modbus TCP protocol is selected. Enter the port number (usually 502 for Modbus TCP) to connect to the PLC.
What Is Modbus TCP/IP? - FS Community
Oct 10, 2024 · The Modbus TCP/IP protocol follows a few key principles, combining features of both Modbus and TCP/IP: 1. Client-Server Architecture: Communication is structured in a client-server model, where a client sends requests, and servers respond. 2. Register-Based Communication: Data is organized into four fundamental data types — Discrete Inputs ...
