Siemens S5 series PLC, memories of the first generation of industrial controllers, is there still SIMATIC S5? The SIMATIC series was first released in 1958, and since then there have been four major generations of products. SIMATIC G was launched in 1959 and revolutionized the field of relay control with its compact and energy-efficient transistors. Although there have been no significant generational changes, SIMATIC N provides faster and more reliable equipment due to the introduction of silicon as a conductive material. In 1973, the company launched the SIMATIC S3 series, which introduced microprocessors and integrated circuits. Due to the advancement of computer science, PLC can be programmed through software for the first time.   In 1979, the SIMATIC S5 series was launched, which widely used microprocessors; S5 PLC uses STEP 5 for programming, which is one of the earliest advanced computer-based PLC programming tools. It first ran on CP/M and MS-DOS operating systems, and later became available on Windows. Due to this flexible programmability, the S5 PLC allows for the control of complex processes. So far, Siemens has developed four product lines: 1958: SIMATIC Version G 1973: SIMATIC S3 1979: SIMATIC S5 1995: SIMATIC S7 The S5 series is sold in 90U, 95U, 101U, 100U, 105, 110, 115115U, 135U, and 155U chassis styles. The sales of the SIMATIC S5 U series began in the 1970s and mass production ended between 2003 and 2005. Afterwards, only spare parts were sold, but some modules were purchased as spare parts. For the SIMATIC S5 system, the product lifecycle ends on September 30, 2020. Starting from October 1, 2020, spare parts will no longer be provided and cannot be repaired. Before September 30, 2020, spare parts can be obtained based on availability and may only be exchanged. For the SIMATIC S5 system, the product lifecycle ends on September 30, 2020.
