TIA Portal Retentive ON Delay Timer Instruction | Siemens S7-1200 PLC Tutorial

In this TIA Portal video tutorial, you'll learn how to use the Retentive ON Delay Timer (TONR) instruction in Siemens PLC programming. The Retentive ON Delay Timer, also known as a time accumulator, is a powerful timer function used in industrial automation with Siemens S7-1200 PLCs.
Unlike the standard ON Delay Timer, the Retentive Timer retains the accumulated time value even when the input signal is turned off. This feature makes it ideal for applications where timing needs to resume from where it left off after interruptions.
🛠️ In this tutorial, you will learn:
• What is a Retentive ON Delay Timer (TONR) and how it works
• Key differences between TON and TONR in TIA Portal
• How to write a ladder logic program using the TONR instruction
• How to trace inputs and outputs using the Signal Monitoring and Watch Tables
• How to simulate the ladder logic program in TIA Portal using PLCSIM
This practical PLC programming tutorial uses a Siemens S7-1200 CPU (CPU 1215C) and is developed using TIA Portal Version 17/18/19/20 (compatible with all). Whether you're a beginner or looking to improve your PLC programming skills, this video will help you understand how retentive timers are implemented in industrial automation.
