Chapter 4
Creating and Editing Messages
4–8
Here are some examples of AUTO REPEAT and CHAIN MSG attributes. In
these examples, there are six messages:
Message 1: chained to 2
Message 2: chained to 4
Message 3: chained to 4
Message 4: neither chain nor auto repeat selected
Message 5: chained to 6
Message 6: auto repeat
Triggering a message causes it to be displayed. To illustrate the operation of
an auto repeat message, we will trigger message number 6. Message 6 is
displayed, then redisplayed. Message 6 continues to be redisplayed until
another message is triggered. If message 5 is triggered, it is displayed,
followed by message number 6. Since message number 6 is an auto repeat
message, message 5, then message 6 repeats until another message is
triggered.
Here are some more examples. Triggering message 2 will cause message 2,
then message 4 to be displayed. Triggering message 3 will cause message 3,
then message 4 to be displayed. Triggering message 1 will cause message 1,
then message 2, then message 4 to be displayed. Triggering message 4 only
causes message 4 to be displayed. Since message 4 is not an auto repeat
message, none of these triggering sequences is repeated.
Message chains up to 35 messages long can be automatically repeated. This
feature can be useful when using the DL20 as an informational display.
Note: Do not use messages with variables when using the chain messages
attribute.
