Siemens 6FX1126-6BA00 Programmable Logic Controller Module

Siemens 6FX1126-6BA00 is a SINUMERIK RAM module that provides 128 KB of RAM for SINUMERIK 800-series CNC controllers, specifically the SINUMERIK 800/8/MS102 configuration. This memory cartridge is designed as a dedicated upgrade or replacement component to expand the controller's working memory, enabling storage of program data and controller operations essential for CNC machining tasks. Identified by the part number 6FX1126-6BA00, it is part of the SINUMERIK 800 family’s memory architecture and is referenced in historical installation lists as a RAM module for MS102 configurations dating back to the early 1990s. Common applications include retrofitting older SINUMERIK 800 machines to restore or extend memory capacity, replacing a failing RAM module, or maintaining memory integrity in legacy CNC systems where reliable RAM is required for accurate program execution and data handling. This module is aimed at technicians and service engineers working with Siemens SINUMERIK equipment, ensuring compatibility with MS102 memory setups and the broader SINUMERIK 800 ecosystem.
