6ES5928-3UB12 is identified by Siemens as a Processor Module within the Simatic S5 family.
For replacement planning, this type of module provides control execution within the automation architecture. Its responsibilities can include logic processing, data handling, communications, and coordination of connected subsystem resources. Selection should account for the intended surrounding hardware configuration.
In a SIMATIC S5 system, module selection is governed by the controller family, rack arrangement, electrical interface, and configured program. The exact article number should be matched before installation. The documented module assignment should remain the basis for selection.
Country of origin is listed as Germany.
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. Final selection should be based on the plant's controlled-equipment records.
