System and method for controlling access to local services without losing failover capibilty
Abstract:
A system and method are provided for controlling access to local electronic devices in an automation network while maintaining failover capability. The method can include the operation of setting a state of a networked device to an online state. Another operation is sending a communication from the networked device to a controller requesting permission to change state of the networked device. The networked device may wait a predetermined amount of time to receive permission to change state. The state of the network device can change without permission from the controller after the predetermined amount of time has passed.
Abstract(Chinese):

提供了一种系统和方法，用于控制对自动化网络中的本地电子设备的访问，同时保持故障切换能力。 该方法可以包括将联网设备的状态设置为在线状态的操作。 另一个操作是将联网设备的通信发送到控制器，请求许可改变联网设备的状态。 联网设备可以等待预定量的时间来接收改变状态的许可。 经过预定的时间后，网络设备的状态可能无法通过控制器进行更改。
