PX 30 and PX 120 Operating Manual
5-1
Basics
• 8 variables are available per text (record), with the numbers 0 ... 7.
• A variable can be a maximum of 10 characters in length.
• If the variable consists of figures, the negative prefix "-" may be placed in front of the
figure as an 11th character.
Please note: If a variable is composed of both positive AND negative numeric values,
with figures after the decimal point, right justification should be selected, otherwise the
variable value could be falsified.
• Text masks (#) must be created in the text for variables. These format the variable
output.
• If the transmitted variable is larger than the variable length edited, (number of text
masks), only the higher value or lower value part will be displayed, depending on the
justification (left/right).
• The text display is line-oriented! This means, for example, that where the PX 30 has 2
lines of 20 characters and the ADIT DOS Editor has a default setting of 40 characters
per line, all characters edited after the 20th column will not be displayed. It also
means that a variable cannot extend over the start or end of a line. For this reason it
is not possible to insert one and the same variable over several lines.
• In parallel drive, if a variable value is transmitted in more than one cycle, the first value
transmitted is taken as the higher value part.
• In serial drive, if a variable value is transmitted in more than one piece of data, the first
value transmitted is taken as the lower value part.
Variable Layout
The following formatting options are available:
• Formatting with the aid of variable masks (ASCII: 23
H
, #)
• Left or right justification
• Display or suppress leading zeros
Each digit in a variable must have a "#"-character as a text mask so that it can be fully
displayed. The control character for the variable number must be placed at the last
"#"-position (see ADIT DOS Manual).
Please note: The control character 23
H
(#) is only visible in the ADIT DOS Editor.
