Description

The 6ES5 376-1AA11 is a 16 KB CMOS-EPROM sub-module designed for the Siemens Simatic S5 programmable logic controller series. This non-volatile memory hardware is used to store compiled STEP 5 machine logic, system parameters, and organization blocks permanently on the host central processing unit. It is widely utilized in industrial environments, such as manufacturing plants and water treatment facilities, where stable, battery-independent program storage is required. By preventing application data loss during power failures or backup battery depletion, this module ensures immediate code re-execution upon power restoration, minimizing system downtime.

Memory Architecture

The module utilizes a CMOS-EPROM matrix with a 16 KB storage capacity. Its architecture supports multi-bit parallel data addressing, providing stable read access speeds synchronized with the S5 CPU execution cycle. Unlike volatile RAM, this module retains its data without the need for electronic refresh pulses. Programming is performed via an external PG series programmer using high-voltage algorithms, after which the module is inserted into the designated slot on the S5 processor.

Features

  • Non-volatile storage ensures data integrity during power loss.
  • 16 KB capacity for complex STEP 5 logic and system blocks.
  • Shielded, anti-static housing protects internal components from electromagnetic interference and vibration.
  • Compact cartridge design for easy installation and replacement in S5 CPU assemblies.

Installation Guidelines

  • Ensure the S5 CPU is powered down before inserting or removing the memory module to prevent electrical damage.
  • Handle the module by its housing to avoid electrostatic discharge (ESD) damage to the internal pins.
  • Ensure the module is fully seated in the designated front slot of the S5 processor assembly.
  • Verify that the module is correctly keyed for the specific CPU slot to prevent misalignment.
