The SIMATIC IPC427D provides machine, plant and control cabinet builders with a high-performance, compact PC platform for use at machine or process level, or in the industrial environment for:

  • Measuring and checking, open-loop and closed-loop control of process and machine data

  • Acquisition, further processing and visualization of data

  • All applications at the machine level – created in C/C++ or with software controller/WinCC flexible/WinCC RT Advanced – which require rugged, ultra-compact IPCs with high computing power

  • Additional new applications such as shipbuilding, building automation, water treatment, RFID

The application spectrum ranges from automation computers fully integrated in TIA with, for example, CPU 1500S software controllers, through C/C++-based automation solutions with the proven SICOMP RMOS3 real-time and multitasking operating system, up to "stand-alone" applications in general IT use. For software products that require Windows 7 Ultimate, the combination of Windows 7 Ultimate is available preinstalled on hard disk or SSD.

The SIMATIC IPC427D has the CE mark for use in industrial applications as well as in domestic, business and commercial environments. It can therefore also be used in building automation systems or in public facilities. The device also has the most important marine approvals, provided that configurations with CFast memory are used.

Due to the fan-free design and use of SIMATIC PC CFast memories, there are no rotating parts which increases system availability. It is possible to position the CFast memory either on the outside to facilitate external replacement, or internally for access protection.

The SIMATIC PC can be ordered in conjunction with WinCC SCADA or WinCC (Advanced, Professional) as SIMATIC HMI packages with a price advantage.
