Online Versus Offline Programming

84 • • • • 6 - Programming
In this chapter, you will discover how to enter and modify logic using
505 SoftShop's features. Remember, in the Windows environment there
is usually more than one way to complete a task. 505 SoftShop provides
keyboard support to access all commands. You may find that the most
efficient method of programming will be through a combination of
keyboard and mouse techniques.
Refer to Appendix A for a concise list of keyboard supported
commands.
Before you begin programming, it is important that you understand the
differences between programming online and programming offline.
While programming online, you are connected to a PLC, which may be
running. Changing logic in one network may affect logic in another
network. These changes may create unexpected or hazardous results.
Editing or modifying a program online may produce unexpected or hazardous
results.
In the online mode, PLC Status in Ladder can be displayed. However,
some editing features are not available, including Cut and Paste.
