    • PURPOSE: To ensure performance of measurement of the transfer capacity as well as the diagnosis of the error detector circuit by installing the means to vary the timing of the data writing and reading to the data transfer buffer device.
      CONSTITUTION: When the data is transferred, data transfer request signal SVI is sent to channel device 13 from the channel buffer (CB) control circuit. Thus, device 13 sends out the data to CB1 to turn on data transmission signal SVO. The CB control circuit confirms signal SVO and produces the transfer timing signal to transmits it to gate 7 and 10. Thus, signal SVO is turned off. Then device 13 confirms the OFF of SVI and turns off SVO to complete transfer of one data. At the diagnosis time, the timing delay setting value is changed freely to be set to register 15, and thus the transfer timing can be changed freely. As a result, the data transfer timing can be varied between device 13 and CB1 to ensure performance the measurement of the transfer capacity as well as the diagnosis for the adaptability decision of the decision of the decision circuit 6 for detection of the overrun.

    • 目的:通过安装改变数据写入和读取数据传输缓冲器设备的时序的方法,确保对传输容量进行测量以及误差检测器电路的诊断。 构成:当传送数据时,数据传送请求信号SVI从通道缓冲器(CB)控制电路发送到通道装置13。 因此,装置13向CB1发送数据以接通数据发送信号SVO。 CB控制电路确认信号SVO并产生传输定时信号以将其发送到门7和10.因此,信号SVO被关断。 然后设备13确认SVI的关闭,并关闭SVO以完成一个数据的传送。 在诊断时刻,定时延迟设定值自由变化,设定为寄存器15,从而能够自由地变更传送定时。 结果,可以在设备13和CB1之间改变数据传输定时,以确保传输容量的测量性能以及用于判定电路6用于检测超限的决定的适应性决定的诊断。
