User requested data is sent to the PLC as part of the I/O scan. Up to 20
ASCII characters can be sent with Block Transfer. Up to 12 ASCII
characters can be sent with Discrete, depending on rack size.
The Enter bit will be set only after all ASCII data requested has been put
into the message. Data should not be considered valid until the Enter bit is
set.
Important: If more ASCII data is requested than can be returned to
the PLC, the excess data will be lost.
To enter a data request, place the cursor just after the point where you want
to insert the request. Use
[CTRL][X]
to specify the insertion position. The
software will insert the symbol for a single byte data request (
↑
).
Insert Time Into a Message With
[CTRL][T]
To enter the time into a message, place the cursor just after the point where
you want the time inserted. Use
[CTRL][T]
to specify the insertion position.
The software will insert the symbol for a time variable (HH:MM:SS).
Note: The time variable occupies 8 of the available 20 characters on a
display line.
You can use the time variable in any Run Mode.
Insert Date Into a Message With
[CTRL][Y]
To enter the date into a message, place the cursor just after the point where
you want the date to appear, and then press
[CTRL][Y]
. The software will
insert the date symbol (DAY MON DT).
Note: The date variable occupies 10 of the available 20 characters on a
display line.
You can use one date variable in any message in any Run Mode.
Notes
We recommend setting individual message attributes such as
Display
Message on What Line
and
Scroll Message
before typing in the words of
the message. This allows you to verify the placement of characters as you
type them.
If
Line Usage
is other than
All Lines
, then the display line on the DL40
does not necessarily correspond to the cursor row value shown on the
message editing window during editing.
