SAFETY NETWORK FOR INDUSTRIAL CONTROLLER HAVING REDUCED BANDWIDTH REQUIREMENTS
摘要
<p>A highly reliable industrial control system provides for the processing of redundant control signals on as little as a single serial network without overloading the network by preprocessing input signals for coincidence and sending only the coincidence signal either periodically or on a change of state. Further compression of sent data is realized by extracting a reduced subset of transmission states from the input signals and transmitting only the transmission states.</p>
