Overview & Concepts
The PDF Reader function in EasyBuilder Pro allows PDF documents to be displayed directly on the HMI during runtime. Operators can open files stored on supported media such as local storage, USB drives, or SD cards. It is commonly used to provide access to manuals, drawings, or work instructions without requiring an external PC.
The PDF Reader is a display-focused object and does not process register data. It presents stored documents within the HMI interface and can be configured to open defined file paths as part of the project. Typical uses include viewing machine documentation, maintenance instructions, or reference materials directly from the HMI environment.
Implementation
Click the PDF Reader icon on the toolbar to create a PDF Reader object.
Or, click [Object] » [Media] » [PDF Reader] in the menu.
