3.3 EDITING LADDER DIAGRAMS
This section describes how to edit ladder diagrams.
Two different methods can be used to edit ladder diagrams. The first
method is offline editing, in which a personal computer for editing
ladder diagrams is used standalone, that is, without being connected to
the CNC (PMC). The second method is online editing, in which a
personal computer for editing ladder diagrams is connected to the
CNC (PMC).
3.3.1 Preparing for Offline Editing
Procedure
1 Check the current programmer mode (offline or online) on the
status bar.
Fig. 3.3.1
2 If the current programmer mode is online, select [Ladder] -
[Online/Offline] to change the current programmer mode to
offline.
3.3.2 Preparing for Online Editing
Starting online editing
Procedure
1 Check the current programmer mode (offline or online). (See Fig.
3.3.1.)
2 If the programmer mode is offline, select [Ladder] -
[Online/Offline] or click the [On Line/Off Line Change] button
to change the programmer mode to online.
3 When you select a ladder program which is not currently used in
the PMC, Ladder Editing Package (Windows) automatically
stores or loads the ladder program. (See Section 5.3,
"AUTOMATIC COMPILATION AND DECOMPILATION,"
for details.)
4 After that, automatic decompilation is performed and ladder
monitoring starts.
5 Then, select [Ladder] - [Ladder Mode] to change the ladder mode
(monitor or editor) to editor.
