Introduction

The nanoLine is a new control platform with easy application programming and flexible, modular configurations. To fulfill the partial requirement of EGR 333, we did research and brainstormed some ideas (both existing and new) for nanoLine controller.

  • 1. Base Units
  • 2. Communications Option modules
  • 3. Real time Clock
  • 4. Expansion I/O Modules
  • 5. Ethernet Communications Expansion

Module

  • 6. Operator Panel
  • 7. Remote mounting for Operator Panel

Further Improvement

  • Shaft’s Encoder Output Frequency is

100KHz

  • PLC input frequency is 10KHz.
  • PLC is not designed for HF (High

Frequency) input

  • Required an interfacing circuit for

frequency mismatch

Frequency Reduction Circuit 100KHz 10KHz

Alternative Control Scheme

After learning microcontroller 80251 assembly language, we figure out that we could implement 80251 instead of nanoPLC. Benefits of 80251

  • Has more operations
  • More customizable
  • Has more memory space

Benefits of nanoPLC

  • Eaiser to program
  • Good for simple control operations
  • Easier to interface into application

Safety

  • Design has rotating wheels

– Wheels could be placed inside clear box

  • Emergency off switch for both

motion and power supply

Safety

slide-13
SLIDE 13
  • Simple design
  • Widespread availability of

components

  • Can be extended and applicable to

any rotary system

Marketability
