7 7 7 7
Specify the lines and column that are to be displayed.
You can provide the PLC editor only with tables with the file name extensions
TAB or P. A temporary file with the name SYS:\TEMP\PLCTABED.TAB is
saved.
With the Modules 9240, 9241, 9245 and 9247 you can check this temporary
file before you place the edited data with Module 9251 into the original table.
7 7 7 7
Enter the editable columns in the sequence in which they are to be
displayed.
Do not enter the line number! It is displayed automatically.
7 7 7 7
Separate the individual columns by a space character. If you have
transferred an empty string, all columns of the original table are displayed.
7 7 7 7
Enter the first and last line to be displayed on the screen. The line numbering
begins with zero. If you enter –1 as the last line, the table will be shown to
its end. If you release all lines and columns for editing, you can choose:
• Whether lines can be deleted and inserted
• Whether the original table should be edited directly
If you edit in the original table directly, you cannot cancel the changes with
Module 9251.
If you do not edit directly in the original table and the PLC program is
recompiled while the PLC editor is open, the editor will be closed without
transferring the changes to the original table.
If the END key or the END soft key is pressed while the PLC editor is opened,
the NC sets M4159. The PLC editor is not closed by the NC. It must be closed
by the PLC with Module 9251.
M4159 is reset when Module 9250 is called.
With Module 9035 you can interrogate the active line in the PLC editor.
