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.

DL40 to clear the message from the display after the
