6ES5350-5AA21 is identified by Siemens as a Memory Module within the Simatic S5 family.
For replacement planning, this component provides a defined storage resource within the control platform, supporting the information requirements of the equipment with which it is paired. The original wiring and configuration records should guide application.
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 plant's maintenance records should support final product 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. Installation should follow the control node's approved hardware records.
