Simatic S5 CPU948 Processor Module
Description

About this product

Here is all you need to know

Delivering super fast bit word oriented processing and extremely fast reaction times for open and closed loop controls, the 6ES5948-3UA13 was an impressive processor module. Designed for the modular Simatic S5-155U range, the CPU 948 Processor Module featured 640KB of random access memory. The fast processing power and memory capacity enabled the module to be installed in a wide range of applications, from medium to extremely large control systems, complex plant automation system and detailed process supervision applications.

Common applications included

  • Bottling plants, packaging machines and automotive industry: Mainly tasks requiring fast bit and word oriented processing and fast reaction times. i.e. extremely fast open and closed loop controls
  • Process and plant engineering:  Tasks requiring an extremely high storage capacity and fast access time
  • Production lines: Tasks that required fast communication with other CPUs installed in the PLC and operating in the multiprocessor mode and with CP modules.

Sadly the unit is now obsolete and no longer fully supported by Siemens. Thankfully, Northern Industrial can still provide new and refurbished CPU 948 module as well as a high quality repair service. We are also able to offer practical advice on upgrade to the latest generation automation platforms like Simatic S7.

Programming and Backing 

A copy of STEP 5 is required to extract, test or commission a user program on the 6ES5948-3UA13.  You will also need a programming cable and a PC running DOS or Windows XP.  Due to the age of the software, it can be difficult to acquire the program and to find a suitable PC.  If you are unsure about using STEP 5, then don’t worry. We’ve got factory trained engineers that are able to come out onsite and extract or modify your program as required. At Northern Industrial we always recommend that you keep a secure backup of your PLC program in case the worst happens.
