Abstract

A control system for enabling I/O boards to access communication networks for receiving and transmitting real time control information over a communication network (18) including a control bus, a node controller (10) and a development system (180). The node controller includes an expert rule based control system and a fuzzy logic subsystem. The fuzzy logic subsystem (340) is used to perform fuzzy evaluations of control data and variables. The fuzzy control system is defined by the user using fuzzy rules, variables and membership functions (354). A plurality of node controllers connected via a network can send and receive data via agents thus enabling a distributed control application. External hardware that connects to I/O devices (26) such as sensors, motors, monitors, machines, etc. can be connected to the node controller via I/O boards that receive and transmit digital signals, representing control information, to the bus. The bus allows any I/O control board (20) having a common interface, such as ISA, PCI, Compact PCI, etc., to connect to the bus by attachment to one of its slots.
