FAQ

Q: What does the "L1" suffix indicate?
A: The "L1" suffix typically indicates a specific firmware revision or DC power variant within the PanelView 550 series.

Q: Can this terminal communicate over Ethernet?
A: No. The 2711-B5A5L1 supports RS-232 (DH-485) only. For Ethernet, consider PanelView Plus models.

Q: What is the application memory capacity?
A: The terminal provides 170 KB of application runtime memory for HMI screens and logic.

Q: Is the 2711-B5A5L1 still manufactured?
A: No. The PanelView 550 is discontinued. Available through surplus channels for legacy system support.

Selection Tips

• Verify DH-485 network compatibility with existing controllers
• Confirm 24V DC power availability
• Consider monochrome vs. color display requirements
• Ensure PanelBuilder 32 software is available
• For new installations, evaluate PanelView Plus 600 or 700 series with Ethernet
