End Of Siemens Support For SIMATIC S5

The SIMATIC S5 system product life cycle ends on the 30th of September 2020. By 1st of October 2020, SIEMENS will no longer provide spare parts and repairs any SIMATIC S5 system in your facility. Until 30th of September 2020, spare parts can be obtained subject to availability and possibly only in exchange.

WHAT IS THE SIMATIC S5?

The SIMATIC S5 was introduced by Siemens in the year 1979 and consists of the  series: 90, 95, 100, 101, 105, 110, 115, 115, 130, 135, 150 and 155. The system includes both compact series as well as highly advanced modular series. Even though it was over 10 years since the latest S5‐series was manufactured SIMATIC S5 is still widely used in industries all around the world.

This automation system is based on Programmable Logic Controllers (PLC). This family of SIMATIC controller offered solutions for highly complex systems. The S5 system represented a secure investment for industries opening a whole world of opportunities for industries demanding increased system functionality to automate their machines.

Hardware

The SIMATIC S5 system is available in a wide range of chassis styles: 90U, 95U, 100U, 101U, 115U, 135U, and 155U. This range of products offered users a choice of many CPU’s, power supplies, I/O, memory, communication ‐, interface – and function modules. The options of the range could be easily chosen based on the user’s requirements and budget. The higher the chassis number, the more sophisticated the PLC becomes. There is also a range of redundant CPU’s providing ultra‐high‐reliability for special systems.

Software

Simatic S5 PLCs were usually programmed with Step 5. This program was used for programming, testing and commissioning the PLCs. The original Step 5 versions manufactured by Siemens ran on the CPM operating system. The versions introduced later ran on MS‐DOS, and then versions of Windows through Windows XP were introduced. The final version of Step 5 was version 7.2. Due to the announcement of obsolescence, no further development occurred by Siemens AG. However software exist by other manufacturers like PG95.

After over 35 years since the system was introduced, it is still used by many factories in the world. However, Siemens AG has now considered the SIMATIC S5 to be obsolete and has dropped their support for it.

WHAT DOES THIS IMPLY

 

  1. Siemens AG will no longer provide spare parts and software support for this family of controllers. Therefore, the cost of spares will become more expensive with reduced availability and increased lead
  1. Since support has been stopped, some specific product knowledge of S5 PLC products and specialist knowledge will not be readily
RECOMMENDATIONS

It is recommended that industries still using the S5 family of controllers upgrade to the Simatic S7 family or higher. In upgrading from the S5 to the S7, the complete upgrade which involves upgrading

both the CPU and I/O modules to S7 or higher is recommended. There a variety of S7 family of controllers designed to meet your needs.
