Summary of steps
Follow these steps to set up local messages:
1. In the Local Messages editor, set up the messages and their trigger values.
2. In the Graphics editor, create local message display objects in the graphic displays in
which you want the messages to appear at run time. For each local message display,
assign a tag or expression to the Value connection and specify the file of messages to
show.
For information about creating graphic objects, see Chapter 20. For information about
setting up local message display objects, see page 21-54.
Use the Local Messages editor
Use the Local Messages editor to create one or more files of local messages. Each file is
stored in the editor’s folder. You can open and work on multiple message files at the same
time.
You can define up to 10,000 messages in each message file.
For details about using the Local Messages editor, see Help.
Prepare to set up local 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 OPC server.
FactoryTalk View writes values to and reads values from the data source.
