Siemens 6ES5340-3KB11 Memory Module

Compact Program and Data Storage for SIMATIC S5

The 6ES5340-3KB11 memory module serves as a storage submodule for SIMATIC S5 programmable controllers. This memory submodule plugs into the CPU or expansion unit to extend available memory capacity. It retains program code and system parameters without needing a backup battery. Consequently, this module protects valuable automation logic from power loss.

Technical Specifications

Memory Retention and Reliability

The 6ES5340-3KB11 employs EPROM technology, so it holds data without any battery. This non-volatile design makes it ideal for critical applications where data integrity is paramount. Users can store complete user programs, block libraries, and system parameters on this module. In addition, the module’s robust construction withstands the typical electrical and mechanical stresses of industrial environments.

Physical Characteristics and Installation

This memory submodule occupies a single slot and fits standard S5 rack configurations. Its 25 mm width allows dense packing within the chassis, making it compatible with all S5 CPUs that support submodule expansion. Users simply insert the module into the designated slot, and the system automatically recognizes the memory. The front panel features a label area for manual identification.

System Compatibility and Application

This memory module works with various S5 CPUs, providing a flexible storage solution. It serves as a reliable repository for machine-specific programs and recipe data. The 6ES5340-3KB11 also provides fast access times, maintaining system performance during program execution. It proves useful for program backup, module replacement, and firmware storage.

Product Status

This module forms part of the legacy SIMATIC S5 product line. Siemens has discontinued this module as a current production item.
