Description
Printing View
Using this list you select view1 to view4 defined under items View 1 to View 4 (see below).
The default view is view4.
The view you select for the Printing View setting is used for printing the LL984 networks.
Column Width
Using this field you can enter the column width as a floating point value (1.0 to 3.0).
For example a value of 3.0 means a 3 times larger column width.
The default width is 1.0.
NOTE: Modifying the Column Width setting does not cause a new Build.
Items of the View 1 to View 4 Settings
The LL984 Editor can display various information concerning variables attached to coils, contacts and function block nodes.
According to the settings for View 1 to View 4 the LL984 Editor displays the following information:
You can switch between the different views defined using CTRL+W or using the Change View Mode button.

Description
Line 1
...
Line 7
For each line, you can select which information should be shown:
  • blank
  • address
  • 984-address
  • variable
  • comment
  • descriptor 1 to descriptor 9
  • topological address
Max characters per cell width
Defines the maximum number of characters visible in one cell (5 to 32). Increasing this value leads to a smaller font size and vice versa.
The default is 10 characters.
NOTE: A high values (for example 32) may lead to a very small (unreadable) font size, but such a value makes sense when used in conjunction with a larger Column Width setting (like 2.0 or 3.0).

NOTE:
For the View 1 to View 4 settings the following restrictions apply:
  • If the value variable is selected in consecutive lines (for example Line 1 and Line 2) the variable name is broken into n lines, if it is longer than the cell width.
    If the value variable is selected, for example, for Line 1 and Line 3 and if for Line 2 any other value is selected, the variable name is truncated at the end of Line 1 and is not broken into Line 3.
    Line 3 starts with the first character of the variable name again.
  • If the value comment is selected in consecutive lines (for example Line 1 - Line 3) the variable comment is broken into n lines, if it is longer than the cell width.
    If the value comment is selected, for example, for Line 1 and Line 3 and if for Line 2 any other value is selected, the variable comment is truncated at the end of Line 1 and is not broken into Line 3.
    Line 3 starts with the first character of the variable comment again.
  • If all 7 lines are configured as blank, the LL984 Editor displays the variable name in Line 7 automatically.
  • Max characters per cell width
    The calculated font height is applied for all kinds of displayed information (address, variable, comment etc.).
  • Blank lines at the top are not displayed. Blank lines in the middle or at the bottom are displayed as empty lines.
