Important: To send any message to a slave,
Port Use
for the RS-485 port
must be set to
DL Slave
. Refer to page 6 – 12 for information
on Ports.
If the
AutoReplace
attribute is active, the message will be sent to the slave
each time it repeats. If the message has embedded variables, it will be sent to
the slave each time new variable values are received during the message wait
time. Possible values for this field include:
Entry:
Which means:
0
Don’t send to slave
1 through 126
Send to the single identified slave address
127
Send to all slaves
Wait Time
This setting can mean either of two things to the message display.
If you have activated
Scroll message
, the value here represents the
scrolling rate in tenths of a second. For example, a value of 8 here will result
in display of the next new character in a message every 0.8 seconds.
If
Scroll message
is not active, then the value here represents the number
of seconds a message will appear on the message display. For example, a
value of 5 here will assure that the message will appear on screen for 5
seconds whenever it runs.
Acceptable values for this field can range from 0 through 31.
AutoClear
Activating this attribute instructs the DL40 to clear the message from the
display after the
Wait Time for message
has expired even if no other
messages have been triggered.
This value applies only to the lines used by a single message. For example, if
this message uses only lines 2 and 3, then only lines 2 and 3 will be cleared.
Lines 1 and 4 will remain unchanged.
Important: AutoClear will de-energize the alarm relay only if the message
which was cleared had energized the relay. A DL50 slave
message display must always be sent a message that
de-energizes the relay.
