Uploading a program in a ControlLogix PLC
If you have a PLC application already running and you want to see the program in the PLC, you can upload the program without stopping the application from running. To proceed, follow the download procedure above; but instead of clicking on Download, click Upload. RSLogix 5000 will ask for a new file to be created. Choose a file name and the PLC program will be transferred into that file.
