Imbedding
Variable Data (Ctrl V)
Imbedding
Formatted Variable
with Decimal Point (Ctrl X)
Variable data from the programmable controller may be imbedded in a
message. Up to twenty valid variables (total) per message may be displayed
or printed this way. To imbed a variable in a particular location, type control
V. The control V will be shown as an up arrow ( ). When the message is
triggered, the first numerical variable in the data queue replaces the up arrow.
Chapter 5 describes this queue, and how to put values in these locations.
Variables can be in the range of -32,768 to +32,767.
This feature allows you to control the displayed format of variable data
within a message.
Variables can be in the range of -32,768 to +32,767.
Three format parameters can be varied:
field width, that is the number of spaces that the variable will take up
decimal place, where a decimal place should be imbedded
whether leading spaces in the field should be padded with blanks or zeros
To imbed a formatted variable into a message, use the message editor and
type control X where you wish the formatted variable to appear in the
message. The control X will be shown as a down arrow ( ) within the
message. The following prompt is displayed:
A field width of 1 through 7 is valid.
Note: If a negative number is displayed, the first character of the field is a
minus sign. You have no control over where the minus sign is placed in the
field. The amount of space taken by the variable when it is displayed, or on
the printout sheet when it is printed, is always equal to the field width.
