Rugged ECU targets construction and agricultural machines

The controllers fulfill safety requirements up to SIL 2 (IEC 61508) / PL d (ISO 13849) and can be programmed either in C or in CODESYS. The safety certified CODESYS Safety SIL 2 speeds up application validation significantly.
The majority of run-time tests that is needed to achieve the diagnostic coverage required for SIL 2 / PL d is performed in hardware by the dual-core lockstep CPU and its safety companion. Therefore almost the full processor power is available for the application. The available memory protection mechanisms allows to execute safety and non-safety software on the same ECU without interference. The time-consuming validation of non-safe software is therefore no longer necessary. Safe data communication is achieved by the standardized CANopen Safety protocol. In case of safety-relevant failure outputs can be shut-off in 3 groups allowing limp-home functionality.
The extensive I/O set with various configuration options makes the HY-TTC 500 controllers suitable for a wide range of high-end applications: for example, a group of 8 I/O pins can be individually configured for use as voltage output, digital output or analogue input. Commissioning time can be improved by using Ethernet for download and debugging purposes.
