Upload
Transfer of the current project or data from the controller to the programming workstation.
The Explain card
- Plain English
- Upload pulls the project out of the controller and onto your laptop. The direction is controller to workstation, and it changes nothing in the controller.
- Example
- You arrive at a site with no drawings and no backup. Upload gives you the running program, minus the comments if nobody stored them in the controller.
- Why it matters
- The program in the controller is the one that actually runs, whatever the office copy says. Upload before you touch anything, and save it with the date, so the last known good state exists somewhere other than in the CPU.
- Hook
- Up is out of the controller.
