Hydac HY-TTC 500 controllers

The HY-TTC 500 range is an electronic control solution designed to satisfy a wide range of applications such as construction and agricultural machines.

The freely programmable controllers with a dual-core ARM Cortex-R4 lockstep processor are protected by a compact, automotive-style housing suitable for harsh environments. The controllers fulfil safety requirements up to SIL 2 (IEC 61508) or 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 extensive I/O set with various configuration options makes the HY-TTC 500 controllers suitable for a wide range of applications: For example, a group of eight I/O pins can be individually configured for use as voltage output, digital output or analog input. Another use case is to build up a centralised architecture using one HY-TTC 500 controller for the whole vehicle. Commissioning time can be improved by using Ethernet for download and debugging purposes.

The majority of run-time tests that are needed to achieve the diagnostic coverage required for SIL 2/PL d are performed in hardware by the dual-core lockstep CPU and its safety companion. Almost the full processor power is therefore available for the application. The available memory protection mechanisms allow executing 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 standardised CANopen Safety protocol. In case of safety-relevant failure outputs can be shut off in three groups allowing limp-home functionality.
