TPW Operational Manual Overview

The TPW Operational Manual serves as a complete guide for understanding and using the function blocks deployed within the TPW system. It is structured to support operators, technicians, and engineers at all levels.

One key section of the manual is the VIDU Part, which is dedicated to providing:

  • Visual Instructions on using each function block, including step-by-step procedures.
  • Navigation Guidance for faceplates, HMI tabs, and alarm interfaces.
  • Role-Based Access Control explanation for Operator, Technician, and Engineer levels.
  • Parameter Editing Instructions showing how to safely configure setpoints and limits.
  • Alarm Interpretation details to understand system behavior under fault conditions.

Whether you're monitoring real-time data, adjusting thresholds, or responding to alarms, the operational manual—especially the VIDU section—equips you with everything needed to operate the system effectively and securely.

The manual is designed to be browsed in-browser or saved as a PDF for offline access.

Welcome to TPW Library Documentation

Installation

  • Download the library.
  • Open CODESYS and import it.

Usage

  • For the Graphic use for the Block such as Block Icon and Faceplates, we provide a brief description that must help you. The details are given below:

Reference Configuration

Users must manually configure the visualization references from the graphics library to ensure proper communication between the block icon and the logic block.

Reference Settings Panel

Steps to Configure References in CODESYS:

  1. Open the visualization properties of the PID faceplate.
  2. Navigate to the References section.
  3. Set the reference path using the graphics library object.
  4. Ensure that the PID block icon and faceplate are correctly linked to the logic block.
  5. Validate and test the visualization in runtime.

Step-by-Step: Set Reference for a Block Icon (e.g., PID)

1. Drag & Drop the Block Icon

  • In Visualization Toolbox, find your block icon (e.g., PID Icon) from the TPW Graphics Library.
  • Drag the icon onto your HMI screen.

2. Open Properties of the Block Icon

  • Click the placed icon once.
  • In the Properties pane, go to the "References" section.

3. Set the Logic Block Reference

  • Click the ... button next to the reference field.
  • A window will open to select the actual logic block instance (e.g., MAIN.PID1).
  • Select your logic block and press OK.

4. Connect Faceplate (if used)

  • Place the Faceplate on screen (optional).
  • Repeat the same referencing steps as above.
  • Now both the Block Icon and Faceplate will communicate with the same logic instance.

Now the icon is linked to your logic.

You may also want to:

  • Use the “Preview” mode to test if data is showing on your block icon.
  • If values are not appearing, recheck the Reference Path.

Common Mistakes to Avoid

Mistake Issue Fix
Forgot to set reference Block shows no value Always assign reference from properties
Assigned wrong instance Faceplate shows incorrect data Double-check the instance you linked
Block not updated at runtime Visuals don’t reflect logic Ensure the block is active in logic and linked correctly

Testing the Connection

  • Press F5 or start the runtime.
  • Interact with the block icon or faceplate.
  • If configured correctly, live process values will update in real-time.

Summary

  • Always set references for block icons and faceplates to link them with real logic.
  • Use the References section in properties.
  • Make sure all objects (icon, faceplate) use the same logic instance.
  • Validate during runtime.
