Analyze process trends?

Monitor production efficiency?

Archive process variables to ensure compliance with government regulations?

For information about setting up data logging, see Chapter 26. For information about

Plan recipes

When planning recipes, consider how they will be used. For example, will recipes be used
to:

Compare tag values to pre-set data values?

Upload tag values to existing or new data sets?

Download values from data sets to tags?

Archive tag values to ensure compliance with government regulations?

Based on such considerations, you can determine:

Which tag sets and data sets to pair together in a recipe file.

Which RecipePlus button actions to use with the RecipePlus selector and RecipePlus
table.

For information about using recipes and creating RecipePlus graphic objects, see
Chapter 29.

Design a secure system

When deciding on your security requirements, consider whether to:

Restrict access to every graphic display to prevent accidental changes.

Restrict access to certain graphic displays.

Have everyone log on.

Use passwords, and if so, whether to have a minimum length, and whether to require
that the passwords are changed periodically.

Allow only authorized users to shut down the application.
