Description

The Siemens 6ES5375-1LA41 is a high-reliability CMOS EPROM memory submodule designed for the Simatic S5 programmable logic controller series. This non-volatile storage component provides a 32 KB capacity, ensuring that critical control programs, configuration blocks, and system parameters are retained securely without the need for battery backup. It is an essential component for industrial automation environments where rapid cold-start recovery and protection against power loss are required to maintain operational uptime.

Features

  • Non-Volatile Data Retention: Utilizes CMOS EPROM technology to ensure program integrity even during extended power outages or voltage fluctuations.
  • Read-Only Protection: Once programmed via a Siemens PG, the data is protected from accidental overwrites, providing a stable execution environment for the host CPU.
  • Robust Interface: Features high-quality gold-plated contacts for reliable, low-resistance connection to S5 CPU memory slots.
  • Industrial Durability: Engineered to withstand the rigors of heavy industrial environments, including temperature variations and electromagnetic interference.

Applications

This memory submodule is widely used in legacy automation systems, including power generation, oil and gas refining, and heavy manufacturing, where Simatic S5 controllers manage critical process logic.

Technical Specifications

Model 6ES5375-1LA41
Brand Siemens
Product Family Simatic S5
Memory Type CMOS EPROM
Capacity 32 KB (32 K x 8 Bit)

Installation Guidelines

  • Power Down: Always ensure the PLC CPU is powered down before inserting or removing the memory submodule to prevent electrical damage to the contacts or the controller backplane.
  • ESD Handling: Handle the module by the edges to avoid electrostatic discharge (ESD) damage to the internal CMOS components.
  • Seating: Ensure the module is fully and firmly seated in the designated memory slot of the S5 CPU.
  • Programming: Note that this module requires an external Siemens programming device for data writing; it functions as a read-only device once installed in the CPU.

FAQ

Does this module require a battery?

No, the 6ES5375-1LA41 uses EPROM technology, which is non-volatile and does not require battery backing to retain stored data.

Can I write to this module while it is in the PLC?

No, this is an EPROM module. Data must be written using a dedicated Siemens programming device before the module is inserted into the PLC.
