Section 6.2: Full OOP Motor Control | Motor FB, UDT and Faceplate | PLC + SCADA Hands-on Guide

This video is a hands-on guide for Section 6.2 of the textbook Control and SCADA Systems by Dr. Chau Truong. In this exercise, we extend the simple motor object into a more complete Motor Function Block. The Motor FB includes manual and auto commands, run feedback, fault detection, reset logic, runtime measurement, speed simulation, and rotation angle calculation. The SCADA part demonstrates how to create a Motor UDT and a reusable Motor Faceplate in WinCC Unified. A single Faceplate design is then reused for multiple motor objects by changing only the Data interface. Main steps covered: Continue from the OOP PLC and HMI setup Create the full Motor Function Block Define Motor inputs, outputs, and static variables Implement Manual and Auto command logic Add command delay fault detection Add Reset logic for clearing faults Add Runtime measurement Add Speed and Angle simulation Create Motor instances: Motor_1, Motor_2, and Motor_3 Connect Cmd to RunFb for Motor_1 and Motor_2 Leave RunFb unconnected for Motor_3 to test fault detection Create the Motor UDT in WinCC Unified Create the Motor_Faceplate type Define the Data interface for the Faceplate Configure Mode, Start, Stop, Reset, Speed_SP, Runtime, Speed, Angle, and Fault Create Motor_1, Motor_2, and Motor_3 HMI objects using the Motor UDT Place three Faceplate instances on the HMI screen Assign Data = Motor_1, Motor_2, and Motor_3 Run HMI Runtime and verify Faceplate reuse Test Motor_3 fault detection and Reset behavior Textbook: Control and SCADA Systems Author: Dr. Chau Truong #PLC #SCADA #TIAPortal #PLCSIMAdvanced #WinCCUnified #OOP #UDT #Faceplate #IndustrialAutomation
