SCADA – Soft PLC Communication Methods

You can use two different methods to exchange data between Soft PLC and Wise SCADA tags. Both methods operate at the same speed and performance; however, Method 2 is recommended for ease of management.

Method 1: Tag Synchronization (Internal)

By double-clicking the “Tag Synchronization” column in the Soft PLC list, you can map tags within SCADA directly to the Soft PLC memory.

Method 2: Fulmatic TCP Driver (Recommended)

The Soft PLC is essentially a virtual Fulmatic PLC running on your computer. Therefore, you can add it to the “Tags” menu just like a physical PLC.

• How to Do It?
  • 1. Add the Fulmatic TCP protocol by right-clicking the Tags section in the project tree and selecting New.
  • 2. Enter 127.0.0.1 (Localhost) in the IP Address field in the connection settings.
  • 3. Enter the port you defined in the Soft PLC settings (e.g., 502) in the Port field.

• Why is it Recommended?
  • This method standardizes tag management. If you decide to replace the Soft PLC with a real physical PLC in the future, you only need to change the IP address. You will not need to reorganize your entire tag structure.
