Plan applications
A well-designed application requires planning. To help you plan, this chapter describes:
 Understand the machines and processes you’re automating.
 Collect data.
 Design an HMI tag database.
 Plan graphic displays and navigating between them.
 Plan languages.
 Plan alarms.
 Provide information for the operator.
 Plan trends.
 Plan recipes.
 Design a secure system.
FactoryTalk View comes with several sample applications that can give you guidance
when planning your application. For instructions on opening the sample applications, see
page 2-2.
Understand the process
Gather information from a variety of sources so you have a complete and detailed
understanding of the machines and processes you’re automating.
To gather information:
 Talk to machine operators and other experts who are going to use the system. Find out
what information they need to optimize machine operations and processes.
 Talk to management and management information systems staff to find out what
information they need to support planning decisions.
 Break up each section of the process into its constituent parts.
 Determine what type of communications you’ll be using—which network types, data
servers, and devices.
 Determine which process variables you need to have access to and identify their
locations in the programmable controllers.
