Prepare to set up information messages
As your application is running, information is continually sent to the data source about the
state of various processes. For example, your application might be monitoring whether a
valve is open or closed, or the temperature in a boiler. Values representing the status of
these processes are sent to the data source.
The data source
The FactoryTalk View documentation uses the term data source as a generic term that
includes all possible sources of tag data, for both data server tags and HMI tags. The data
source can be memory or a device such as a programmable controller or an OPC server.
FactoryTalk View writes values to and reads values from the data source. The data source
is set up to exchange information (in the form of numeric or string values) between
FactoryTalk View and the machine that your application is controlling.
Identify the tags and values to monitor
To set up information messages, determine which tags associated with machine processes
to monitor, and identify the values for those tags that will trigger information messages.
For information about creating tags, see Chapter 7.
