Frequently Asked Questions

Product-specific configuration, compatibility, application and ordering guidance for 6ES5945-7UA23.

Which S5 rack is the CPU 945 intended for?

Use it in the SIMATIC S5-115U central-rack configuration documented for the installed controller.

Which CPU resources should be checked against the old program?

This 6ES5945-7UA23 variant has 384 KB memory; the current CPU record also lists 256 timers and 256 counters.

How should the STEP 5 project be secured before exchange?

Archive the complete STEP 5 program and configuration and record the installed CPU and memory-module identifiers.

Which interface connections need a before-and-after check?

Document the 15-pin PG port, any plug-in second interface, cable positions and communication parameters.

When can the CPU operate in a multiprocessor rack?

Only when the S5-115U rack and application are configured for the documented multiprocessor arrangement.

What proves a successful restart?

Confirm RUN/STOP and SYS FAULT indications, then test the required I/O and communications under the site commissioning procedure.

Can an S7 CPU replace it without engineering changes?

No. Siemens provides S5-to-S7 migration guidance, but program conversion, I/O mapping and application testing are required.
