13-Word Message

This is a display and return message. When the message is displayed,
you are required to enter data from the module keypad. It is
functionally similar to the 12-word message except a user-defined
initial value is displayed in the lower right-hand corner of the display:

• A signed integer value may be entered using the numeric keys

followed by the

>(17(5@

key. When the

>(17(5@

key is

pressed, the value is stored at the data entry destination address,
and the screen returns to the previous display.

• The message cannot be overwritten while data is being entered.

• Pressing the

>(17(5@

key without entering data writes the

initial value to the data entry destination address and clears the
message from the display.

• Pressing the

>(6&@

key clears the message from the display and

does not alter the value previously stored at the data entry
destination address.

The message text is stored at the local file address, followed by the
data entry destination address block. The initial value word is
automatically assigned to the next data file address following the data
entry destination address block.

To enter the message text into processor memory, refer to your
software user manual.

Important:

The programming device does not allocate the memory
location described in the data entry destination address
block. See your software user manual for information
on using memory mapping to verify that the memory
location exists or to create the data location if it does
not exist. Otherwise the DTAM displays

,OOHJDO

&RPPDQG

when it attempts to enter the value into a non-

allocated data entry destination.
