The primary objective of safety is to avoid hazardous situations that pose health risks to humans. Measures and functions to prevent hazards also reduce the risk of damage to machines, thus increasing process reliability. Complex facilities, such as CEP hubs, usually use dedicated safety PLCs that are networked with the program logic PLC via safety gateways and fieldbuses, such as ASIsafe, PROFIsafe, and DeviceNet safety. SICK offers a comprehensive range of safety sensors, actuators, safety relays, and safety controllers for highly effective, fully compliant safety solutions. In addition, SICK supports you with professional services along the entire safety chain from risk assessment, system design, engineering with development of the logic/function blocks all the way to commissioning of globally compliant safety concepts and solutions.
