4.4Establishing the online connection between the PC and CPU 312C

You must establish an online connection between the PC and CPU 312C for the following:

•Downloading and testing the control programs

•Displaying and changing the operating state of the CPU 312C

•Displaying the module status

•Hardware diagnostics

To establish an online connection, you must connect the PC and CPU 312C to one another via the MPI interface.

Establishing the online connection

STEP 7 Lite attempts to establish the online connection on startup.

If the connection exists, the operating state of the CPU 312C is displayed in the status bar as “STOP”.

If no connection exists, the status bar displays “Disconnected”.

1.If the connection does not exist, establish the connection between the CPU 312C and your PC.
