Step 3—Add an HMI Server
This step applies to distributed applications only. Stand-alone
applications contain one HMI server that is created automatically
when the application is created.
The HMI server stores project components (for example, graphic
displays), and serves these components to clients. The server also
contains a database of tags, and performs alarm detection, and
historical data management (logging).
For details, see Chapter 5, Working with distributed applications.
Step 4—Plan how you will access data
This step is necessary so you can complete steps 5, 6 or 7.
To access data, you need to plan two things:
• how the application will communicate with the programmable
controllers or devices on the network.
• once communications have been set up, how the application will
access values in the programmable controllers or devices.
Setting up communications with devices
To access values in programmable controllers or devices, you need to
• know what kinds of controllers or devices you are using.
• plan how the application will communicate with the controllers or
devices.
