Product description
Siemens 6ES5948-3UR12 is a CPU 948R central processing module for the redundant SIMATIC S5-155H automation system. It is intended for installed systems in which two subsystems form a high-availability controller and where the CPU version must exactly match the existing hardware and project configuration. This order number provides 640 KB of integrated RAM for the user program. The CPU supplies 256 timers and 256 counters for time- and count-dependent control tasks. The Siemens programming manual also documents 2,048 flags and 32,768 S flags for internal states and system-related signals. Documented expansion limits are a maximum of 1,024 digital inputs, 1,024 digital outputs, 448 analogue inputs and 448 analogue outputs. The module is therefore designed for extensive S5-155H applications with distributed or central process I/O. Its enclosure measures 40.6 × 233.4 × 160 mm and the specified weight is 1,000 g. As an R variant, the CPU is designed for redundant processing in the S5-155H system. Integrated memory and system resources support continued use of substantial STEP-5 programs, while timers, counters and flags represent typical sequencing, monitoring and interlocking functions in the installed plant. For maintenance and replacement, the full article number 6ES5948-3UR12, designation CPU 948R, 640-KB memory configuration and S5-155H target system are the essential matching points. Other CPU-948 or CPU-948R variants may have different memory capacities or system assignments and cannot be treated as equivalent based only on the series name. Before installation, compare the rack configuration, redundancy link, installed memory card, STEP-5 program version and I/O addressing with the system documentation. The module supports targeted restoration and long-term spare-parts provision for established SIMATIC-S5-155H control systems without unnecessary changes to the existing automation architecture.
