PID Controller Tuning - Training Guide
============================================================

MINIMUM RESOLUTION: 980 x 600 px
RECOMMENDED: 1920 x 1080 (16:9) or larger

SIMULATOR OVERVIEW
----------------------------------------
PID controller tuning simulator covering P, PI, and PID modes, Ziegler-Nichols tuning, and loop response analysis per ISA-5.1 and IEC 61131.

Standards: ISA-5.1 · IEC 61131 · ISA-88

INTERFACE LAYOUT
----------------------------------------
- LEFT PANEL: System controls (Start/Stop/ESD/Reset, Mode toggle)
- CENTER: P&ID schematic with real-time process visualization
- RIGHT PANEL: System gauges, operational checklist, alarm list

OPERATING PROCEDURES
----------------------------------------
  Step 1: Set controller to manual mode
  Step 2: Adjust output to achieve setpoint
  Step 3: Record process response
  Step 4: Calculate Kp Ki Kd from response
  Step 5: Enter tuning parameters
  Step 6: Transfer to auto mode
  Step 7: Apply step change — verify response
  Step 8: Adjust parameters for performance

SCENARIOS
----------------------------------------

  Manual to Auto Transfer:
  Bumpless transfer from manual to auto — tune PID for stable control.

  Ziegler-Nichols Tuning:
  Perform open/closed-loop tuning to determine optimal PID parameters.

  Cascade Control Setup:
  Configure primary-secondary cascade and tune for disturbance rejection.

ALARM RESPONSE
----------------------------------------
  OSCILLATION [WARNING]: Process variable oscillating
  WINDUP [WARNING]: Integral windup detected
  DEVIATION [ALARM]: Process variable deviation >10%
  OUTPUT_SAT [WARNING]: Controller output saturated
  SENSOR_FAIL [ALARM]: Process variable sensor failure

CONTROLS
--------

- STOP: Normal shutdown
- EMERGENCY STOP: Immediate shutdown of all systems
- RESET: Clear ESD condition and reset to standby
- TOGGLE MODE: Switch between Manual and Auto control
- Fullscreen: Click the fullscreen button in header
