The control operation fails because the operation signal of the mouse cannot change the state of the process channel.On the one hand,the hardware of the process channel itself may be faulty,and on the other hand,it may be the software defect of the operator station itself.,resulting in no response.After checking that the function of the process channel is normal,check the operator station,restart if necessary,and initialize the operator station.

控制操作失效是由于鼠标的操作信号不能改变过程通道的状态，一方面可能是过程通道硬件本身故障，另一方面可能是操作员站本身软件缺陷，在设备负荷过重或打开的过程窗口过多时，导致不响应。在检查过程通道功能正常后，应对操作员站进行检查，必要时进行重启，初始化操作员站。
