Section 4.6: Compressor Service Monitoring | TON/TONR/CTU | FBD/SCL | PLC + SCADA Hands-on Guide

This video is a hands-on guide for Section 4.6 of the textbook Control and SCADA Systems by Dr. Chau Truong. In this exercise, we implement and test a compressor service monitoring system. The PLC program controls the compressor with ON and OFF commands, measures the current running time using TON, accumulates the total running time using TONR, and counts the number of start cycles using CTU. This video continues from the same TIA Portal, PLCSIM Advanced, and WinCC Unified project setup used in the previous hands-on videos. Main steps covered: Create PLC tags: On, Off, Compressor, RunTime, AccTime, and CycleCount Create the Compressor service logic using FBD Add TON, TONR, and CTU blocks Create HMI tags and link them to PLC tags Create the Compressor Service HMI screen Configure ON and OFF button events Configure the Compressor status indicator Add IO fields for RunTime, AccTime, and CycleCount Run HMI Runtime and test the FBD logic Replace the FBD logic with SCL, download, and verify it again in the same HMI Runtime Confirm that RunTime resets, AccTime is retained, and CycleCount increases after each compressor start Textbook: Control and SCADA Systems Author: Dr. Chau Truong #PLC #SCADA #TIAPortal #PLCSIMAdvanced #WinCCUnified #IndustrialAutomation
