Description

The Siemens 6AV3971-1NA01-0DA0 is a 64 KB non-volatile memory module designed for the SIMATIC OP20 operator panel. This component serves as a critical storage medium for system configurations, screen layouts, and operational parameters within the HMI unit. By providing reliable data persistence, it ensures that essential settings are maintained during power cycles, supporting stable operation in demanding industrial environments such as chemical processing, packaging, and manufacturing.

Features

  • Non-Volatile Storage: 64 KB capacity utilizing solid-state technology to retain critical HMI data, including screen masks and alarm logs, without the need for external battery backup.
  • Seamless Integration: Engineered for direct installation into the OP20 internal expansion slot, ensuring secure physical connection and reliable communication with the host terminal.
  • Operational Reliability: Designed to maintain data integrity under standard industrial operating conditions, preventing configuration loss during power interruptions.
  • System Compatibility: Optimized for use with legacy SIMATIC OP20 interfaces, facilitating consistent performance alongside Profibus DP and RS-232 communication protocols.

Installation Guidelines

  • Ensure the OP20 terminal is completely powered down and disconnected from the power supply before attempting to install or remove the memory module.
  • Handle the module by its edges to avoid electrostatic discharge (ESD) damage to the sensitive electronic components.
  • Align the module carefully with the internal expansion slot on the OP20 main logic board; ensure it is fully seated to prevent intermittent connection issues caused by vibration.
  • Verify that the module is firmly secured within the slot to maintain reliable contact with the host terminal's bus interface.
  • Once installed, perform a system check to ensure the HMI recognizes the memory module and that all stored configurations are correctly loaded.

FAQ

Is this module compatible with other SIMATIC HMI series?

No, this specific memory module is engineered exclusively for the legacy SIMATIC OP20 operator panel. It is not compatible with newer HMI generations.

Does this module require a battery for data retention?

No, the 6AV3971-1NA01-0DA0 utilizes non-volatile solid-state memory, which does not require battery power to maintain stored data.
