Understanding the process you are automating
To design an effective control system using FactoryTalk View Site Edition, it is important
to understand the process you are automating.
Gather information from a variety of sources, and pay attention to details that might affect
the overall performance of the system. To get planning underway:
Talk to operators and other experts who will use the system, to get their input about
ways to optimize plant operations.
Talk to management and information systems staff, to find out what they need to
support planning and design decisions.
Break up the process into its constituent parts. This will help you visualize how parts
of the automated system might be distributed over a network.
Identify the process variables you need, and their locations in the programmable
controllers or devices.
Determine which types of data servers the system will use.
Determine which processes will generate alarms, and how to monitor alarms.
Determine which parts of the process should be secured, and the most efficient ways
to restrict user access.
Assess the need for redundancy in different parts of the system.
