Since safety-oriented product development is characterized by particularly challenging conditions, namely high costs and a somewhat small sales potential, finding a way to ensure long-term investment viability is an absolute imperative for system and product manufacturers within this market segment. Investment protection depends on various parameters: the availability and reliability of the hardware and software that is used, a safe legal basis for their use, and, of course, the scope and proper budgetability of development costs. openSAFETY is a safe choice in every respect for product manufacturers and end users. This solution gives them a ready-to-use safety stack with a proven track record of many years in actual applications. In contrast to dedicated, proprietary developments, there are no high development costs for this solution, no lengthy periods of time must be spent on it, and no demanding know-how requirements must be met. As it is already TÜV-certified and incorporated into the IEC 61784-3 standard, openSAFETY also minimizes development risks. Last not least, users also enjoy an extremely sound legal basis for long-term investment viability, since openSAFETY has been made available under the BSD open source license.
