Siemens 6ES5513-3MB12 Memory Module

This memory module stores user programs and system data securely. The Siemens 6ES5513-3MB12 belongs to the SIMATIC S5 product family. You can insert this module directly into the CPU’s memory slot. Its non‑volatile design retains data without external power.

Physical Dimensions and Form Factor

The Siemens 6ES5513-3MB12 measures 8.0 cm in total length. Its width reaches 5.5 cm with a height of 1.8 cm. This memory module weighs only 0.06 kg. A 64‑pin dual in‑line connector interfaces with the host CPU. Two plastic latches secure the module firmly in its socket.

Memory Organization and Capacity

This module provides 32 kB of EEPROM storage space. The Siemens 6ES5513-3MB12 stores both program code and data blocks. The module supports up to 10,000 write cycles per memory cell. Consequently, you can update programs frequently without wear concerns. A built‑in write‑protect switch prevents accidental data overwrites.

Compatibility and System Integration

The Siemens 6ES5513-3MB12 fits SIMATIC S5 CPUs exclusively. You can install this module in the designated memory expansion slot. The host system automatically recognizes the module upon power‑up. Therefore, no additional configuration steps are necessary.

Data Protection and Write Security

A hardware write‑protect switch prevents accidental data overwrites. You can enable this protection by sliding the side switch. The Siemens 6ES5513-3MB12 also includes software access control. This dual protection ensures critical program integrity at all times.

Installation and Handling Notes

Insert the module gently into the 64‑pin socket. Press evenly until both latches click into place. Avoid touching the gold‑plated connector pins directly. Static discharge can damage the internal memory circuits. Use an anti‑static wrist strap during installation.
