WinCC Unified Faceplate Tutorial: Build a Reusable Motor Faceplate in TIA Portal Using UDTs and Dynamic SVGs
Build a reusable WinCC Unified motor faceplate in TIA Portal to eliminate repetitive tagging and reduce HMI errors. This step by step tutorial shows how to create a dynamic SVG motor graphic in the Project Library, define a PLC UDT and function block structure, bind the UDT to a faceplate tag interface, and deploy multiple instances by connecting each faceplate to a different data block. You will also learn how to version and release library types, move PLC data blocks into the HMI tag table, and validate everything using WinCC Unified runtime simulation. Perfect for engineers who want scalable HMI design patterns for motors, valves, and other standard equipment.
