Description

Siemens 6ES5947-3UA22 is a SIMATIC S5 CPU 947 processor for the S5-155U platform. The CPU 946/947 architecture distributes processor functions across the associated modules. The CPU 947 contains the specified user-program memory and operating-system storage. Its front interface provides the connection described for programming and communication equipment. The full ordering number identifies the required processor configuration.

This processor is used when maintaining an existing SIMATIC S5 control installation. The installed CPU arrangement and memory configuration must be reviewed together. Preserve the operating program and system records before replacement. The product name must not be confused with a separate fail-safe CPU designation. Migration to a newer controller requires an engineered conversion rather than an assumed direct exchange.

Applications

System integration

6ES5947-3UA22 supports maintenance of legacy SIMATIC S5-155U automation systems. Match the processor to the existing rack, associated CPU arrangement and control program. Replacement work should follow the installed system documentation.

Maintenance planning

For lifecycle planning, 6ES5947-3UA22 is an existing-platform spare rather than a modern controller migration kit. A migration project must review the application program, I/O arrangement and communication paths. Keep the original hardware records available during planning.

FAQ

Is 6ES5947-3UA22 identified as a CPU 947F?

The exact product designation is CPU 947 for SIMATIC S5-155U. Do not interpret the abbreviated product wording as a separate fail-safe designation.

Can 6ES5947-3UA22 be replaced directly by an S7 controller?

A migration requires engineering review of the program, hardware and communication. A migration reference is not a drop-in replacement approval.

Why check the associated CPU arrangement when sourcing 6ES5947-3UA22?

The CPU 946/947 system distributes its functions across the associated modules, so the installed arrangement must be identified.

What documentation should accompany a replacement inquiry for 6ES5947-3UA22?

Provide the full module label, rack configuration and a current backup of the S5 application and system records.

Can I see the actual condition of 6ES5947-3UA22 before ordering?

Yes. We confirm the offered condition, provide actual-item photos and test each item before delivery. The agreed warranty is 12 months.

When can available 6ES5947-3UA22 stock leave after payment?

Available stock is dispatched immediately after payment is received. Courier tracking is provided after dispatch.
