The configurable nucleus has been expanded for support of the new SIMATIC IPC227D and downloads, as far as necessary, the drivers for the onboard interfaces USB 2.0, Gigabit Ethernet, PROFINET IO, PROFIBUS DP, CAN bus, and diagnostics drivers for hardware-level functions.

The PROFINET onboard interfaces of the SIMATIC IPCs offer diverse options for integration of real-time solutions with SIMATIC IPC into PROFINET networks. PROFINET RT (Real-Time) and PROFINET IRT (Isochronous Real-Time) are supported in the operating modes IRT with high flexibility or IRT with high performance with cycle times up to 250 µs and jitter accuracy <1 µs.

The configurable nucleus additionally allows use of the following functions:

• Up to two CompactFlash cards, SIMATIC CF cards also with S.M.A.R.T. monitoring
• A battery-backed SRAM of up to 2 MB for retentive data
• Control of freely programmable user LEDs
• Expanded diagnostics functions for battery monitoring, temperature monitoring, and fan monitoring
• Functions for using the watchdog
• Operating hours counter
• HD monitoring with S.M.A.R.T.

For using the development environment Eclipse from the development package RMOS3-GNU (V2.1 and higher), the C/C++ programmer is provided with all functions of the programming interfaces for PROFINET, PROFIBUS, CAN Bus and hardware diagnostics in the form of an online help and code completion. The PROFINET function interface is identical here to the calls described in the programming manual of the SIMATIC NET CP16xx "SIMATIC NET IO-Base User Programming Interface".
