Description

The Allen-Bradley 2711-NB4 (2711NB4) is a dedicated real-time clock (RTC) replacement module engineered for specific PanelView operator terminals. This hardware accessory ensures that the operator interface maintains accurate date and time tracking, which is essential for precise system event sequencing, alarm logging, and diagnostic auditing in industrial automation environments. By providing a stable time reference, it enables reliable data correlation across system logs.

Features

  • Provides autonomous time and date tracking independent of external network synchronization.
  • Maintains timekeeping accuracy across power cycles.
  • Compact design for seamless integration within PanelView hardware.
  • Essential for accurate timestamping of alarm and diagnostic data.

Applications

This module is designed for use in industrial control panels utilizing Allen-Bradley PanelView 300 keypad terminals and PanelView 550/600 touch-screen-only operator interfaces. It is typically deployed in applications where local time-stamping of process events is required for regulatory compliance or maintenance troubleshooting.

Installation Guidelines

  • Ensure the operator terminal is fully powered down and disconnected from the power source before attempting to install or replace the RTC module.
  • Handle the module using standard ESD (Electrostatic Discharge) precautions to prevent damage to sensitive internal components.
  • Insert the module into the designated slot on the back of the PanelView terminal, ensuring it is firmly seated in the internal system bus connector.
  • Verify that the terminal is correctly reassembled before restoring power.
  • Once installed, configure the time and date settings through the PanelView terminal's configuration menu to ensure synchronization with the local plant time.

FAQ

Does the 2711-NB4 require external power?

No, the module is powered directly through the internal system bus of the compatible PanelView terminal.

Is this module compatible with all PanelView models?

No, it is specifically designed for the PanelView 300 keypad terminals and the PanelView 550/600 touch-screen-only models. Please verify your specific terminal model before installation.

Does this module need network synchronization?

The 2711-NB4 operates autonomously to maintain time, meaning it does not require an external network time server to function, though it may be used in systems that perform periodic time updates.
