SCADA Tutorial #14 | Server–Client Architecture & Multi-SCADA Communication
📌 In this lesson of the Wise SCADA training series, we take an in-depth look at the Server–Client architecture, which enables multiple SCADA systems to communicate and share data over the network.
You will learn how to configure a Wise SCADA project as a Server, expose its Tags to other systems, and connect another Wise SCADA project as a Client to read and write data in real time.
Throughout the lesson, we cover advanced SCADA networking scenarios such as:
- Creating a Server using Modbus TCP Slave and Wise SCADA Protocol
- IP and Port-based access control -Tag-level read/write authorization
- Data update using Trigger and Period methods
- Redundant communication with multiple IP addresses
- Instantly creating Client projects by cloning the Server project without manual Tag mapping
This architecture allows hundreds of SCADA systems to communicate seamlessly without additional coding, making it ideal for large-scale and distributed industrial automation systems.
