Lecture Notes: Mitsubishi PLC Programming with GX Worker 2 PID Control

Introduction

  • Presenter: Engineer Bashar
  • Topic: Mitsubishi PLC Programming using GX Worker 2
  • Main Focus: PID (Proportional, Integral, Derivative) Control Loop
  • Call to Action: Subscribe to Atlas Automation BTC channel, over 200 videos on industrial equipment

PID Control Loop Overview

  • Continuous Operation: Input command PID s1, s2, s3, d
    • s1: Target
    • s2: Measured value present
    • s3: Parameter
    • d: Output

Programming Steps

  1. Initial Setup

    • Open contact X0
    • Application instruction: PID D0
      • D0: Target
      • D2: Measured value (PB)
      • D200: Parameter
      • D20: Output

  2. Field Programming

    • Use open contact X1
    • Use SM411: 200ms clock relay
    • Offhand contact X2
    • Increment:
      • Instruction: INB increment D2
      • D2 (Measured value, PB) increment command
    • Decrement: Instruction DEC Decrement D2

  3. Parameter Configuration

    • Always on switch FM400
    • Move instruction for parameter setting
      • Proportional Integral Derivative Settings
      • Sampling time t_s and economic settings
      • Operation setting ACT
      • Input filter constants 0-99%

  4. Gain and Time Settings

    • Proportional Gain (Kp)
      • Set using MOV K300 to D203
    • Integral Time (Ti)
      • Set using MOV K8 to D204
    • Differential Gain (Kd)
      • Set using MOV K5 to D205
    • Differential Time (Td)
      • Set using MOV K18 to D206

Program Compilation

  • Compile and start the simulation
  • X0: Turn on and simulate
  • X1: On for decrement value
  • Important components:
    • Input Filter Constant
    • Operational Setting ACT
    • Proportional Gain, Integral Time, Differential Gain/Time
    • SM400: Always on relay
