摘要: A distributed, electronic process control system is disclosed having a plurality of remotely located stations interacting to control a complex industrial process. The stations communicate via a process communication link which supports secure, multi-master communication. The link provides a transparent medium of exchange for the secure transfer of process status and control information among the stations, such that each station may initiate and control system communication for a predetermined time period.
