Siemens LOGO! PLC: A Practical Guide to On/Off Delay Timers in Function Block Diagram (FBD) | 2026
Unlock the power of time-based control in your automation projects. This comprehensive guide from Parveen Automations provides a step-by-step tutorial on programming On-Delay (TON) and Off-Delay (TOF) timers using the Function Block Diagram (FBD) language on a Siemens LOGO! PLC.
This video is designed for a global audience of engineering students, automation technicians, and seasoned engineers looking to master essential PLC logic. We will cover:
✅ The fundamental principles of On-Delay and Off-Delay timers.
✅ How to configure timer parameters within the LOGO! Soft Comfort environment.
✅ Practical examples of implementing timer logic for common industrial applications.
✅ A clear, visual demonstration of how the logic operates in a simulated environment.
By the end of this tutorial, you will have the confidence to integrate and troubleshoot time-dependent sequences in your own PLC programs, a critical skill for any automation professional.

*Safety Disclaimer:*
This video is for educational and informational purposes only. The logic demonstrated here is in a controlled, simulated environment. Applying any automation logic to live machinery without a comprehensive risk assessment, proper guarding, and adherence to local and international safety standards (like ISO 13849 or IEC 62061) is extremely dangerous. Incorrect timer settings can cause unexpected machine movement, leading to severe injury or equipment damage. Always have a qualified professional oversee the implementation and commissioning of industrial control systems.
