SafeSquare GmbH Logo

If you need to develop products for your safety technology, SafeSquare is your service partner.  SafeSquare GmbH, a young and innovative company, offers a comprehensive and integrated service portfolio for safety technology in accordance with IEC 61508.  SafeSquare has a background of many years of experience, from project management, training, consulting, concept development, cooperation with certification bodies, via hard- and software development, documentation, prototyping, environmental audits, to testing and production management.

Staff members and partners have developed SafetyLon - a safe add-on technology for LON.  SafetyLon and normal LonMark devices can share media and normal routers so that SafetyLon can be installed withiin new and existing networks.  Present LNS tools and SafetyLon Plug-ins are used for the non-safe and safe system integration process.  SafetyLon has been developed according to IEC 61508 and is suitable up to SIL 3.  Detailed information is available on request.
