Frequently Asked Questions
Q: Can I hot-swap the PP846 3BSE042238R1?
A: No. The PP846 is a panel-mounted HMI with 24 V DC power and serial/Ethernet communication; it is not designed for hot-swap replacement. You must de-energize the 24 V DC supply and isolate all communication links before removal to avoid display blackout, communication loss, and unintended manual control actions in critical process applications.colletplc+1
Q: Is the PP846 3BSE042238R1 obsolete? Are there direct replacements?
A: Yes, the PP846 is effectively obsolete in new ABB production. Direct replacements are other Panel 800 variants (e.g., PP846A, PP845, PP865) or upgraded 800xA HMI panels (e.g., PP877, PP888), but verify display size, keyboard layout, communication port count, and Control Builder M / 800xA project compatibility before swapping.
Q: Will I lose my HMI application when replacing this panel?
A: Yes, if you do not back up first. The HMI screens, alarms, and scripts reside in the 12 MB Flash memory and are managed via Control Builder M or 800xA HMI configurator. Before replacing the PP846, you must upload the full application to a CompactFlash card or PC, then download it to the replacement panel after installation and hardware configuration (IP address, serial port settings).colletplc+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original ABB packaging, never installed) or tested used units with 12–24 month warranty. Genuine ABB factory-new PP846 panels are rare. Request photos of packaging, nameplate data (3BSE042238R1, HW/FW version), and display test reports for audit.
