📌 About This Video:-
In this technical tutorial, we dive deep into the world of High Speed Counters (HSC) in PLC programming. Learn why standard PLC scan cycles often miss high-speed signals and how a dedicated HSC hardware chip solves this problem for precise industrial automation.
We provide a step-by-step configuration guide using Siemens MicroWin SMART software for the S7-200 PLC. Whether you are working with rotary encoders for motor speed, positioning, or material length measurement, this video covers the essential logic and math calculations needed for a successful implementation.
What you will learn in this video:
The difference between standard PLC scan cycles and HSC.
How to choose between Single Phase, Dual Phase, and Direction Control modes.
Step-by-step High Speed Wizard configuration in MicroWin SMART.
Wiring encoders (A/B Phase) to PLC terminals.
Converting encoder pulses into physical measurements (MM) using math logic.
Using Interrupt Routines (CV = PV) for real-time machine actions.
