You can send variables to the DL40 Plus from a PLC via the Remote
I/O, RS-485, RS-232, or Parallel port. Variables can be sent to
messages only in the Message/Variable/Slave or Message/Variable
Run modes. To insert variables in a message, press 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 a message depends on
your hardware and the selected Run mode.
Insert Formatted Variable [CTRL][V]
Use [CTRL][V] to insert a BCD or binary variable in a message.
Specify the variable type.
When you press [CTRL][V] , you are prompted to enter 3 parameters:
Parameter Acceptable values
Variable Size 1 to 7 (including decimal point)
Decimal Point Position
(number of places 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) Y(es) or N(o)
The variable symbol _ _ _
S_ _ will appear in your 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 ability to
modify the parameters shown above.
Background messages do not support inserted variable data.
