Replacement & Compatibility FAQ
Q: Can the 2711-K5A5X replace a 2711-K5A2 directly?
A: Yes, if your application uses DH-485. The 2711-K5A5X supports both DH-485 and RS-232, making it a superset of the 2711-K5A2.
Q: Will my existing PanelBuilder application files work on a replacement unit?
A: Yes, .PBA files created in PanelBuilder 1400e are fully compatible with any 2711-K5A5X unit of the same firmware revision.
Q: Is the PanelView 550 series still supported by Rockwell Automation?
A: The PanelView 550 series has reached end-of-life (EOL). Rockwell recommends migrating to PanelView Plus 6 or PanelView Plus 7. However, replacement units remain available through authorized aftermarket suppliers like Konmask.com.
Q: Can I use a PanelView Plus 600 as a direct replacement?
A: Not as a drop-in replacement — the PanelView Plus 600 requires application migration using FactoryTalk View ME and may require panel cutout modification. It is recommended for new installations or planned upgrades.
Q: What is the lead time for the 2711-K5A5X?
A: Typically 3–7 business days for in-stock units. Contact us for current availability.
