FPGA based evaluation board for safety solutions up to SIL 3 and PLe, Cat4

The SafeFlex – Functional Safety Development Kit (FSDK) consists of an FPGA based evaluation board. With the realization of an FPGA based solution in safety related systems, a considerable reduction in costs for development and certification is achieved. Time to market is reduced noticeably.
The SafeFlex – FSDK includes an instruction manual for the whole safety development and assists you to reduce risks, design costs, design time, process overhead. It improves your platform development, flexibility, modularity and safety integrity level (SIL).

Customer benefits

  • Satisfy the IEC 61508 up to SIL 3
  • Satisfy the ISO 13849 up to Pl e Cat 4
  • Minimize your risk during the development
  • Reduce your development costs
  • Reduce your time to market

Typical applications

  • Industrial
  • Automotive
  • Energy Management

System overview

openSAFETY Solution

The concept is discussed with the TÜV Rheinland for safety systems up to IEC 61508 - SIL3 and is depicted in following block diagram. SafeFlex – FSDK is supporting now fieldbus communication with a safety protocol. The first supported fieldbus is the Ethernet POWERLINK from our partners EPSG and Softing. openSAFETY from EPSG is used as safety protocol.
The architecture describes a system consisting of two FPGAs. Each FPGA design consisting of two softcore processors with openSAFETY stack in lockstep. One of the FPGAS has an additional processor with a POWERLINK stack.
