Product Overview
The Allen Bradley 2711P-RR256 is a SODIMM RAM memory module designed for PanelView Plus 700–1500 operator terminals. It provides system memory expansion and runtime performance support for HMI applications running FactoryTalk View ME.
This module is used inside PanelView Plus logic modules to enhance application execution speed, data handling capacity, and overall system stability, especially in complex HMI projects with large tag databases or heavy animation/trending loads.

Function and Working Principle
The 2711P-RR256 acts as volatile working memory for PanelView Plus systems:
- Installed into the logic module as internal RAM expansion
- Provides additional workspace for Windows CE runtime processes
- Supports execution of FactoryTalk View ME applications
- Improves performance for:
- Large HMI screens
- High tag count systems
- Alarms, trends, and logging operations
- Data is temporary (lost on power-off), but improves runtime efficiency
Role in PanelView Plus Architecture
This memory module supports:
- HMI runtime execution stability
- Faster screen rendering and navigation
- Improved PLC communication buffering
- Handling of large .MER applications
- Better multitasking of alarms, tags, and animations
It does not store applications permanently—that role belongs to flash memory inside the logic module.
Industrial Applications
- Large manufacturing HMI systems
- Complex packaging and assembly lines
- Power plant operator stations
- Oil & gas monitoring panels
- Water treatment SCADA interfaces
- Pharmaceutical production control systems
- High-density PLC visualization systems
Installation Guidelines
- Install inside compatible PanelView Plus logic module (RP series)
- Use proper ESD protection
- Ensure power is OFF before installation
- Seat module firmly into SODIMM slot
- Verify system recognizes memory after boot
- Match firmware compatibility with logic module version
Compatible Components
- PanelView Plus 700 / 1000 / 1250 / 1500 terminals
- Logic modules (RP1, RP2A, RP6, RP7A, RP8D, etc.)
- FactoryTalk View Studio ME
- Industrial Ethernet and PLC systems
- HMI runtime applications (.MER files)
Key Advantages
- Expands system RAM for HMI runtime performance
- Improves stability in large applications
- Supports high tag count and complex graphics
- Reduces system lag in heavy SCADA/HMI loads
- Industrial-grade reliability for continuous operation
- Easy internal upgrade/maintenance
Technical FAQs
What is the main purpose of this module?
It provides additional RAM for PanelView Plus systems to improve HMI performance.
Does it store HMI programs permanently?
No, it is volatile memory. Applications are stored in flash memory, not RAM.
Will removing it affect the system?
Yes, it may cause reduced performance or failure in large applications.
Is it required for all PanelView Plus systems?
Not always—only higher-performance or expanded systems use it.
Can it be upgraded?
Only within compatible PanelView Plus logic module hardware limits.
Conclusion
The Allen Bradley 2711P-RR256 SODIMM Memory Module is a performance enhancement component for PanelView Plus HMI systems. By expanding RAM capacity, it improves runtime efficiency, supports larger applications, and ensures stable operation in demanding industrial automation environments.
