Rockwell Automation 2706-MB1 MESSAGEVIEW 421 SOFTWARE MANUAL - Manual (Page 158)

7–37 Creating Messages
Publication 2706-817
Note: A long message may be checked in the Terminal View if you:
•
set the insertion pointer in the Message Edit box at different
points along the message; the message in the Terminal View starts
with the insertion point.
•
if the All Line attribute is set, use the Return (Enter) key to break
up the message into segments.
Note: If Auto Clear is enabled and Wait Time is 0, Scroll must be
enabled. If it is disabled, the application will not pass Validation.
If All is selected in the Line attribute, Scroll must be disabled.
Hidden
A Hidden message is triggered like any other message but not
displayed. When the Hidden attribute is enabled its message never
appears on the terminal display.
Since a Hidden message is not displayed, it cannot support any type
of operator action.
Note: Set the HE Stack attribute for a Hidden message to log a
Display Variable into the stack without displaying it.
Note: Set the Slave Enable attribute for a Hidden message to have a
slave device display a message that does not appear on the master
device’s display.
Text Attributes
Several attributes define the way in which a message is displayed.
Center
A message is left justified by default. To toggle between centered
and left justified for the message in the Message Edit box, do one of
the following:
•
select the Center check box to enable or disable centering
•
click the Center or Left Justify icon
•
select Align from the Format menu, and choose Left or Center in
the menu that appears.
If you want a message to be right justified, insert spaces at the start
of the message in the Message Edit box, and check the result in the
Terminal View.
Note: The number of displayable characters in a centered message
must be less than or equal to the number of characters per display
line available for the selected text size.
