摘要： A communication control system is provided that performs communications satisfying a request for industrial applications and a request for open protocol communications at the same time. To this end, in the invention, a high-priority communication section performing critical communications to provide real time property and reliability, and a low-priority communication section performing communications based on an open standard protocol coexist in a same communication station.

摘要： Herein disclosed is a duplex computer system to be used in process automations or factory automations. The system is constructed of two computer (or processor) systems connected with a common backplane bus and a plurality of I/O units to be controlled by those computer systems. Each of these systems is composed of a CPU having a self-diagnosis function for outputting a ready signal indicating whether or not its operations can be normally accomplished, a communication interface unit for interfacing with the backplane bus, and a duplex control unit that receives the ready signal output from the CPU in order to determine which of the computer systems is to be brought into a control status while the other is brought into a standby status. Thus, it is possible to provide a highly reliable system, in which the duplex control can be accomplished without providing an independent duplex control unit between the two computer systems, and in which trouble experienced by one computer system will not exert any influence upon the operations of the other computer system.
摘要翻译：这里公开的是用于过程自动化或工厂自动化的双工计算机系统。该系统由与公共底板总线连接的两个计算机（或处理器）系统和由这些计算机系统控制的多个I / O单元构成。这些系统中的每一个由具有自诊断功能的CPU组成，用于输出表示其操作是否能够正常完成的就绪信号，用于与背板总线接口的通信接口单元和接收该背板总线的双工控制单元从CPU输出准备好的信号，以便确定哪个计算机系统将进入控制状态，而另一个进入待机状态。因此，可以提供高度可靠的系统，其中可以在两个计算机系统之间不提供独立的双工控制单元的情况下实现双工控制，并且一个计算机系统经历的故障不会对操作产生任何影响的其他计算机系统。
