Red Lion LEGEND - Manual (Page 35)

MESSAGE PRIORITY (PRIOR - 1)
Messages can be assigned a priority from 1 to 8 (1 = highest priority).
Messages of equal or higher priority will supersede or replace a displayed
message of lower or equal priority.
BLINKING MESSAGE (BLNK-YES/NO)
This parameter enables the message to blink at a one second rate when
displayed. This mode is only available with 1 or 2 line block messages.
MULTIPLEX (MUX - YES/NO)
Allows a message to be multiplexed with the indication display. The unit
displays the requested message then the indication display each for 2
seconds. Message multiplexing is only available with 1 or 2 line block
messages.
MAINTAINED/MOMENTARY MESSAGE REQUEST
MNT. REQ (Maintained Request)
Programming a message for maintained request allows the message to be
re-requested if the message has been displaced by another message. To be
re-requested, the User Input or output requesting the message must be active
(maintained) and the interrupting message must have been cancelled.
Maintained messages of the same priority are treated as follows when more
than one message requesting input or output is active. A new message of the same
or higher priority will always be requested when the request source is activated.
When a maintained message is cancelled, the message of the requesting input or
output of highest priority is displayed. The priority order, from highest to lowest,
for the various request sources are: User Input 1, 2, 3, 4, User F1, User F2, Binary
Message Request inputs, and Outputs 1 to 6. User Input 1 (programmed for
REQ.MSG) has the highest priority and Output 6 has the lowest.
MOM. REQ (Momentary Request)
Once a momentary message is displayed, if another message is requested
and displaces the momentary message, the momentary message is cancelled.
It will not be requested again unless the User Input or output is deactivated then
activated again. If no other messages are requested while the momentary
message is displayed, it remains on the display until cancelled as programmed.
MESSAGE CANCELLATION
Any displayed message is immediately displaced when another message of
equal or higher priority is requested. A displayed message can also be
cancelled by activating a User Input programmed for the Cancel Message
function, or via the serial port. If no other function purposely cancels a
message, it is cancelled per the cancellation mode programmed. A message
that is programmed for maintained request will be re-requested when the
message times out or is cancelled, if the request source (User Input or output) is
still active. If several maintained messages’ request sources are active, and the
last requested message times out or is cancelled, the message associated with
the highest priority input will be requested next (See Maintained Request).
LATCHED - Latched messages can only be cancelled by the methods
described above.
TIMED - Timed messages automatically cancel at the end of the specified
time period as programmed in “MESSAGE TIME”. A Character or block
scrolling message will scroll to the end before being cancelled. This causes
the message to remain on the display longer than specified by the time-out
value. A 2 Line Block message will stay on the display for a minimum of 2
sec. (1 block time) before timing out. The message time out value is
initially set to 5 seconds when the timed mode is selected.
TIL END - A message programmed for this mode will automatically get
cancelled when the output or User Input programmed to request this
particular message deactivates. Only one request source should be
programmed to request a message set for Til End. A Til End message that is
requested by serial communication will be immediately cancelled, if there
is an inactive request source set to request that message.
MESSAGE TIME
This parameter is available only if the message cancellation mode is set for
timed. The message time for a timed message can be programmed from 1 to
599 seconds.
MESSAGE COLOR
Can be programmed for Red or Green on dual color models.
