Replacement & Compatibility FAQ
Q: Can 2711P-B4C20D replace 2711P-B4C20A?
A: Yes, the “D” suffix denotes a later hardware revision. Application files created for the “A” revision are generally compatible, but verify firmware version in FactoryTalk View ME before deployment.
Q: Is 2711P-B4C20A compatible with CompactLogix or ControlLogix?
A: Not natively via DH-485. For CompactLogix/ControlLogix, select a model with EtherNet/IP such as 2711P-B4C20D8.
Q: Can I use a third-party HMI as a drop-in replacement?
A: Functionally possible with protocol converters, but application re-development is required. We recommend staying within the PanelView Plus 6 family for zero-re-engineering replacement.
Q: What is the lead time for 2711P-B4C20A?
A: In-stock units ship within 1–3 business days. Contact us for current availability.
Q: Do you provide a test report or inspection certificate?
A: Yes. Power-on test reports and certificates of conformance are available upon request.
