Conversion Options The approach to conversion described in this guide provides you with enough
information to convert everything in your application to use the D-series enhanced
interface. Of course, not every application needs to have every part converted.
Depending on your application, several options are available. The following list
outlines some of the major enhancements you might need to make, starting with the
easiest options and working to the most complex:
Running your process at a high PIN
Allowing your process to be created by a high-PIN process
Opening a high-PIN process
Allowing your process to be opened by a high-PIN process
Creating and managing a high-PIN process
The following paragraphs indicate where in this guide you need to turn to find
procedural information on the above options.
