To determine the firmware version of your processor
Important: The RSLinx service must be installed and running on your computer in order for
RSLogix to communicate with the processor. Refer to your RSLinx and RSLogix documentation for
help configuring and troubleshooting these applications.

communication port on the front of the processor.
2 Start RSLogix 5000 and close any existing project that may be loaded.
3 Open the Communications menu and choose Go Online. RSLogix will
establish communication with the processor. This may take a few moments.

Connected To Go Online dialog box will open.
