Siemens SIMATIC IPC – Industrial PCs for Industrial Automation

The Siemens SIMATIC IPC (Industrial PC) systems represent a family of industrial computers designed for advanced automation applications, industrial supervision, data management, and IT/OT integration.

Siemens IPC systems are used across numerous industrial sectors such as automotive, packaging, food, pharmaceutical, energy, logistics, CNC, and smart manufacturing, where reliability, operational continuity, and resistance to harsh industrial environments are essential.

The main Siemens industrial PC families include:

• Panel PC
• Box PC
• Rack PC
• Embedded PC

Each category is designed for specific application requirements and is identified by different Siemens MLFB product roots.

Siemens SIMATIC HMI Legacy S7 – roots 6AV3 / 6AV4

In the Siemens catalog, the 6AV3… and 6AV4… roots identify a family of legacy HMIs developed for integration with first-generation SIMATIC S7 systems.

These devices represent the evolution of SIMATIC S5 HMIs and constitute an intermediate phase between legacy systems and more modern platforms (Basic, Comfort, Unified).

Siemens SIMATIC S5 HMI Legacy – 6AV36xx / 6AV37xx product code prefixes

In the Siemens catalogue, the 6AV36xx and 6AV37xx product code prefixes identify a family of legacy HMIs developed for integration with SIMATIC S5 systems.

These devices represent the first generations of Siemens human-machine interfaces and are still installed in numerous industrial plants, where production continuity depends on the proper maintenance of legacy technologies.

Siemens SIMATIC HMI Legacy – 6AV3 / 6AV4 roots

Siemens SIMATIC HMI Legacy systems include the first generations of human-machine interfaces used in industrial automation systems, particularly within SIMATIC S5 environments and early SIMATIC S7 architectures.

Mainly identified by the 6AV3 and 6AV4 MLFB roots, these devices are still installed today in many production plants, where ensuring operational continuity remains essential.
