More About Variables
You can send variables to the DL40 from a PLC or via the Parallel
Input Port. Variables can be sent to message only in the
Message/Variable/Slave or Message/Variable Run Modes. Insert
variables using the [CTRL] key in combination with a letter.
Commands to add or modify variables include:
Command Function
[CTRL][V] Insert a BCD or binary variable
[CTRL][F] Change the formatting parameters of a variable
[CTRL]W] Insert ASCII or BCD variable data
[CTRL][X] Insert request for ASCII input data
[CTRL][T] Insert the system time into a message
[CTRL][Y] Insert the system date into a message
The number of variables you can insert in any one message depends
upon your hardware and the selected Run Mode.
Insert Formatted Variable With [CTRL][V]
Use [CTRL][V] to insert a BCD or binary variable into a message.
Specify the variable type.
When you press [CTRL][V], the software will ask you to enter 3
parameters:
Parameter Acceptable values
Variable Size 1 to 7 (including decimal point)
Decimal Point Position
(number of placed after the
decimal point)
0 to 6 (the maximum value is one less
than the variable size selected above)
Suppress Zeroes
(appearing in front of the
first significant digit)
Yes or No
The variable symbol _________ appears in the message at the
variable’s location.
The difference between a formatted variable entered with
[CTRL][V] and an unformatted variable entered with [CTRL][W] is
the flexibility to modify the parameters shown above.
Note that neither AutoRun Messages or Background Messages
support inserted variable data.
