Save the message file with the name “Conveyor belts.”
5. In the Information Setup editor, assign the Information_messages tag to the Value
connection, and select the Conveyor belts message file.
At run time, when the value of Conveyor_1_status changes to 1, the first message is
shown (in the default information message display). When the value of
Conveyor_2_status changes to 1, the second message is shown.
Information messages and trigger values
Create messages associated with each tag value change that you want to inform the
operator about. Assign each message a trigger value, and set up the data source to send the
trigger value to the Value connection. You can use both HMI and data server tags.
The trigger value can be any non-zero integer value (positive or negative). Trigger values
do not need to be contiguous, but they must be unique for each message. For example, you
could use trigger values of 1, 2, and 3, or values of 10, 20, and 30.
Trigger values cannot be 0. Digital tags have two possible values, 0 and 1. Therefore, if
you use a digital tag you can only use the value 1 to trigger a message. If you want to use
a digital tag to trigger two different messages, create an expression that adds 1 to the
digital tag’s value. That way, you can use the trigger values 1 and 2.
If you use an analog tag or an expression, you can use any non-zero integer or floating-
point value to trigger an alarm. Floating-point values are rounded to the nearest integer.
For information about how values are rounded, see page 7-2.
You can create multiple information message files, but you can use only one message file
at run time. For information about using a different message file, see page 27-8.
Create information messages in multiple languages
FactoryTalk View 5.00 and later supports information messages in multiple languages.
When you create information messages, they are in the current application language. You
can export the information messages for translation and then import them back into the
application. For details, see Chapter 12.
Language switching information messages in FactoryTalk View
ME Station 4.00
For applications that will run in FactoryTalk View ME Station version 4.00, use the
CurrentLanguage( ) expression function to specify message offsets in the information
message file. In the file, divide your messages into sections for each language. For
information about the CurrentLanguage( ) function, see page 23-14.
