Siemens 6FX1120-4BD03 is a Communications CPU for the Sinumerik product family.
Processor and controller modules execute configured control functions, coordinate data from I/O and communication resources, and manage the operating sequence assigned to their control node. The original equipment schedule should guide compatibility review.
Within the assigned control-system position, this product is associated with the Sinumerik family and the CNC controls category. Configuration and compatibility should be confirmed for the exact system in which it will be used. The documented module assignment should remain the basis for selection.
When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. Existing connection and module records should guide replacement work.
