ABSTRACT:
A plant loop communication system utilizing a plurality of Loop Interface Slave (LIS) modules, each of which being an intelligent slave module incorporating its own microprocessor, is described. The use of such a module permits off-load processing so that receiving, transmitting and message processing cam occur simultaneously. A Superloop Bus Module (SBM) contains a data base which allows the asynchronous operation of the system. A Superloop Storage Module (SSM) stores data for transmission onto the loop and/or incoming data for transmission to an operator console.
