Wait time for message
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.
A value of zero (0) will allow the message to remain displayed until the next
message trigger is received. This will allow the PLC or SLC to control
messaging times.
Acceptable values for this field can range from 0 through 31.
Clear message automatically
Sometimes referred to as AutoClear, activating this menu item 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.
