Abstract
In a plant supervisory system, many computers (functional servers) that distributively perform functions are connected through two types of transmission paths (such as a control bus and an information bus). The control bus is used to transmit periodic data such as process data. Event data is transmitted through the information bus. Thus, many computers can be connected. In addition, the latest value of process data can be referenced by each computer.
