    • A network system for carrying out communication between a control station and a plurality of devices connected to a network. The communication includes data communication which requires real-time attributes and message communication which does not require real-time attributes. The data communication includes a first data communication, and a second data communication. The system includes a plurality of transmission queues for temporarily storing transmission data provided in the control station, wherein one of the queues holds transmission data for the second communication. After the first data communication is carried out in accordance with a predetermined cycle time, an appropriate switching between the message communication and the second communication is carried out in the remaining time of the cycle time to complete one cycle, whereafter the cycle is repeatedly carried out.
    • 一种用于在控制站和连接到网络的多个设备之间进行通信的网络系统。 该通信包括需要不需要实时属性的实时属性和消息通信的数据通信。 数据通信包括第一数据通信和第二数据通信。 该系统包括用于临时存储在控制站中提供的传输数据的多个传输队列,其中一个队列保存用于第二通信的传输数据。 在按照预定的周期时间执行第一数据通信之后,在循环时间的剩余时间内执行消息通信和第二通信之间的适当切换,以完成一个周期,然后循环被重复执行 。

    • A local area network system in which a logical ring is formed by at least part of said node stations to pass a token frame from one station to another in an endless and cyclic fashion allowing each of said node stations which has received is allowed to transmit data, and said data comprises event data. Since only the stations holding the token are allowed to transmit cyclic data and event data, each station is not required to be equipped with a monitoring timer so that not only the LAN can be constructed economically but also transmission efficiency can be improved through speed up in determining the completion of data transmission.
    • 一种局域网系统,其中由所述节点站的至少一部分形成逻辑环,以令无限循环方式将令牌帧从一个站传递到另一个站,从而允许已经接收的每个所述节点站传送数据 并且所述数据包括事件数据。 由于只有持有令牌的站才能发送循环数据和事件数据,所以每个站不需要配备监视定时器,因此不仅可以经济地构建LAN,还可以通过加快传输效率来提高传输效率 确定数据传输的完成。
