Product Overview
Siemens 6ES5947-3UA22 is the CPU 947 F module used as the memory and interface section of the SIMATIC S5-155U CPU 946/947 central processing unit. Its memory unit contains the integrated user RAM and system memories, while its communication unit provides the programmer connection and access to the CPU memory.
The documented CPU architecture supports STEP 5 program execution, floating-point arithmetic, cyclic, time-driven and interrupt-driven processing, communication with communications processors and multiprocessing configurations. The optional 355 memory module expands the available user memory for larger applications.
Key Functions
User and System Memory
The module contains 64 Kwords of integrated user RAM for code and data, together with operating-system EPROM and system-data RAM.
STEP 5 Processing Resources
The CPU 946/947 architecture processes STEP 5 operations and provides floating-point arithmetic, selectable interrupt priorities and cyclic, time-driven and interrupt-driven execution levels.
Programming and Operator Connection
The 15-pin front connector links the CPU to a programmer, operator panel or SINEC interface module through the documented serial interface.
Expandable Program Capacity
A 355 memory module with approved submodules can extend user memory by up to 384 Kwords, producing a maximum configuration of 448 Kwords.
