Functional Safety
Machine and processes continue to become faster, more flexible and more powerful. In order to keep up with increasing complexity of automation and protection of safety operators and technicians while maintaining productivity and efficiency, protective measures have evolved. Traditionally, safety systems have been implemented separately to automation systems, operating independently and often in parallel to the automation system. Today as automation systems become more intelligent then so must the safety system. Using new technology to improve the functional operation of a machine is known as functional safety.
