ABSTRACT:
A stealth interface for an intelligent front-end communication system couples a plurality of actively redundant process control computers to a computer network. The stealth interface in each of the actively redundant process control computers includes a multi-ported memory for storing dynamic data associated with the physical process and for transferring this data to a front end computer which is in communication with the computer network. The multi-ported memory also includes a mailbox section for storing messages sent between the front end computer and its actively redundant process control computer. The stealth interface also includes a guardian circuit which ultimately controls the ability of the front end computer to write information to specific memory locations in the multi-ported data memory.
