An online connection between the programming device and CPU is required for loading
programs and project engineering data as well as for activities such as the following:
● Testing user programs
● Displaying and changing the operating mode of the CPU (Page 258)
● Displaying and setting the date and time of day of the CPU (Page 267)
● Displaying the module information
● Comparing and synchronizing (Page 266) offline to online program blocks
● Uploading and downloading program blocks
● Displaying diagnostics and the diagnostics buffer (Page 267)
● Using a watch table (Page 260) to test the user program by monitoring and modifying
values
● Using a force table to force values in the CPU (Page 261)
To establish an online connection to a configured CPU, click
the CPU from the Project Navigation tree and click the "Go
online" button from the Project View:
If this is the first time to go
online with this CPU, you
must select the type of PG/PC
interface and the
specific
PG/PC interface from the Go
Online dialog before
establishing an online
connection to a CPU found on
that interface.
Your programming device is now connected to the CPU. The orange color frames indicate
an online connection. You can now use the Online & diagnostics tools from the Project tree
and the Online tools task card.
