Auto Clear
Use the Auto Clear check box to clear the message from the display
after its Wait Time has expired. Disable Auto Clear to display the
message until another message is triggered (or comes to the top of
the queue) that is assigned to the same line(s).
Note: If Wait Time is 0 and Scroll is disabled, Auto Clear must be
disabled. If it is enabled, the application will not pass Validation.
If a message has a Function key or keys enabled, the Jog Mode
aspect of the Auto Clear attribute is used.
•
Non–jog mode: if Auto Clear is enabled, the Function key
message is terminated as soon as a Function key operation is
completed (including Hold Time if any)
•
Jog mode: if Auto Clear is disabled, the Function key message
remains active until:
–
the the terminal operator presses the
[0]
and
[+/-]
keys
on the
terminal at the same time
–
the controller triggers Special Message 9901, Clear Display
–
the controller triggers Special Message 9903, Reset Terminal
–
the terminal operator resets the terminal manually.
Jog mode is discussed in detail on Page 4–21.
Scrolling
Use the Scroll check box to enable scrolling.
•
The Scroll attribute is disabled to pop the message onto the
display.
A message longer than the display is wide appears in segments,
each remaining for the Wait Time specified for the message.
•
The Scroll attribute is enabled to scroll the message onto the
display from the right side, one character at a time.
A message too long for the display scrolls off the display at the
left. When the last character appears, the message remains for its
Wait Time before it is terminated.
If the Auto Clear attribute is not set, the message will continue to
scroll until another message is triggered or queued for the same
line(s).
When Scroll is enabled, the Scroll Time list box is activated. Use
the Scroll Time list box to set the time interval between one
character appearing and the next. Range is 0.1 to 5 seconds; default
is 0.2 seconds.
