Allen-Bradley 2711P-RR256 RAM Module
Configured for high-speed dynamic data buffering and memory expansion in Allen-Bradley PanelView Plus operator terminal architectures, the Allen-Bradley 2711P-RR256 (2711PRR256 RAM Module) provides direct physical/electrical execution for runtime screen rendering, alarm history logging, and trend data management.
Suffix Breakdown & Model Matrix
The catalog number structure defines specific memory capacity and hardware subsystem parameters:
- Base Prefix (2711P-): Identifies compatibility with the Allen-Bradley PanelView Plus operator terminal hardware platform.
- Accessory Type (-RR): Designates a Random Access Memory (RAM) SODIMM expansion card assembly.
- Memory Capacity (-256): Specifies 256 MB of high-speed system dynamic memory allocated for logic module application processing.
Hardware Specifications
| Parameter | Specification |
|---|---|
| Model | 2711P-RR256 |
| Brand | Allen-Bradley |
| Origin | USA |
| Weight | 0.32 lbs (0.15 kg) |
| Dimensions | Compact SODIMM form factor profile |
| Operating Temp | 0 deg C to +55 deg C |

Deterministic Network & Backplane Integration
Configured for complex HMI application processing in Allen-Bradley PLC networks, the module expands internal system RAM to prevent dynamic buffer overruns during high-density data polling. The expanded memory space preserves high backplane bus communication velocity and speeds up tag database synchronization across EtherNet/IP, ControlNet, and DH+ communication networks. Firmware flash compatibility ensures seamless OS execution and stable graphic rendering across active industrial control loops.
Frequently Asked Questions
Q: Is electrostatic discharge (ESD) protection necessary when installing the 2711P-RR256 module?
A: Yes, proper grounding procedures, including an anti-static wrist strap, must be observed to prevent static electricity from damaging the sensitive CMOS memory chips on the SODIMM board.
Q: Can the 2711P-RR256 memory module be hot-swapped while the logic module is energized?
A: No, main system power to the PanelView Plus terminal must be completely disconnected before opening the logic housing to insert or remove the SODIMM memory card.
Field Installation Guidelines
Disconnect all AC/DC power sources from the PanelView Plus unit and place the logic assembly on a static-dissipative work surface. Remove the rear protective access cover to expose the internal SODIMM memory slot. Align the polarization notch on the 2711P-RR256 edge connector with the corresponding ridge in the card socket, insert the module firmly at a 45-degree angle, and press downward until the side retaining clips snap locked. Reinstall the protective cover securely before applying power to the terminal.
