SAFETY SERVICES ON A STANDARD NETWORK

摘要

Communication networks have changed the look of today's automation systems by distributing processing, sensors and actuators to where they are required. The ODVA says that CIP Safety provides the same benefits to safety systems. CIP Safety extends the industry standard CIP base services by adding CIP Safety distinctive services to transport data for CIP based networks such as EtherNet/IP with high integrity. It can offer a scalable, network independent approach to safety networking, where the safety services are described in a well-defined layer, allowing the underlying network services to be changed. This approach is said to enable the seamless routing of safety data, allowing users to create end to end safety chains across multiple links.
