Abstract
A process controller implements smart field device standards and other bus-based architecture standards so that communications and control among devices are performed so that the standard control operations are transparent to a user. The process controller allows attachment to a theoretically and substantially unlimited number and type of field devices including smart devices and conventional non-smart devices. Control and communication operations of the various numbers and types of devices are performed simultaneously and in parallel.
