How it applies
- Engineering: Compact panels like these connect to the machine controller via Ethernet or serial links. Check that the panel's supported protocols, screen size and IP rating fit the machine.
- Maintenance: For replacements, check whether the original model is still available or which successor model and software version the vendor recommends, and whether the existing project can be converted.
- Documentation: Name the exact model and order number in the parts list and refer to Schneider Electric's manuals for installation and panel settings. Screenshots in the machine's operating manual should come from the delivered project, not from vendor demos.
Keep in mind: Product names, brands and features change; the Magelis ranges have been rebranded. Check designations, successors and software against Schneider Electric's current documentation before publishing.
