PDF Format (Acrobat Reader)

The Portable Document Format (PDF) from Adobe allows documents to be displayed, independently of the software that was used to create them.
In order to display PDF files, you will need the Adobe Reader, which can be obtained from Adobe or may be found on the Beckhoff CD Products & Solutions.

CHM Format (HTML Help)

The Compiled HTML Format (CHM) from Microsoft has been the standard for Windows help files from Windows 98. The CHM format is based on HTML files, but has the advantage over a collection of HTML files that

• A navigation tree makes it easy to obtain an overview
• It is easy to perform full text searches
• It is possible to collect the information on one topic (multiple pages, images) into one file

Any PC on which Windows 98, Windows ME, Windows 2000, Windows XP or Windows Vista and Version 4.0 or above of the Internet Explorer is installed should be able to display CHM files.
For Windows 95 and Windows NT 4.0 you need an additional viewer (hhupd.EXE); this can be obtained from Microsoft, or found on the Beckhoff DVD Products & Solutions.

If opened CHM files show a structure tree but no pages, please read our notes about using CHM format.
