Description
The Siemens 6ES5375-0LA15 is an 8 KB EPROM memory submodule designed for the legacy SIMATIC S5 programmable logic controller (PLC) platform. This non-volatile storage component is essential for maintaining control logic, system parameters, and application firmware, ensuring data persistence during power interruptions. It is widely utilized in industrial automation environments where program integrity and rapid system recovery are critical, such as manufacturing, power generation, and heavy process industries.
Features
-
Non-Volatile Storage: Provides reliable, long-term retention of STEP 5 machine code, organization blocks, and function blocks without the need for backup batteries.
-
Hardware Protection: The EPROM architecture prevents accidental runtime overwrites or software-driven corruption once the logic is programmed.
-
Robust Design: Features gold-plated pin interfaces to ensure stable connectivity and resistance to contact degradation in high-vibration industrial settings.
-
Direct Integration: Designed for seamless insertion into the memory slot of compatible SIMATIC S5 central processing units.

Installation Guidelines
- Ensure the PLC is powered down before inserting or removing the memory submodule to prevent electrical damage to the module or the CPU backplane.
- Handle the module by its edges to avoid electrostatic discharge (ESD) damage to the internal memory components.
- Verify that the module is fully seated in the CPU memory slot to ensure proper contact with the bus pins.
- Keep the module away from high-EMI sources and ensure the cabinet environment remains within the specified operating temperature range of 0 to 60 deg C.
FAQ
Is this module compatible with all S5 CPUs?
The 6ES5375-0LA15 is designed for the SIMATIC S5 series; however, compatibility depends on the specific CPU model's memory slot requirements and the total memory addressing capacity of the controller. Please verify your CPU manual for supported memory submodule types.
Does this module require a battery?
No, this is an EPROM (Erasable Programmable Read-Only Memory) module. It is non-volatile and does not require a battery to retain its programmed data.
