    • A facility environmental control ("FEC") system is disclosed that communicates using an open network management protocol such as the simple network management protocol ("SNMP"). The FEC system includes a first plurality of FEC devices operable to obtain data concerning the environment of a facility and a second plurality of FEC devices operable to receive command signals and perform operations that affect the environment of the facility in accordance with the received command signals. The system further includes a control system operably connected to the first and second plurality of FEC devices, and a control system agent operably connected to the control system. In general, the control system receives data from the first plurality of FEC devices and provides command signals to the second plurality of FEC devices. The control system agent is preferably operable to receive and send SNMP messages to a management node, wherein said SNMP messages include information concerning the operation of the control system.
    • 公开了使用诸如简单网络管理协议(“SNMP”)的开放网络管理协议进行通信的设施环境控制(“FEC”)系统。 FEC系统包括可操作以获得关于设施的环境的数据的第一多个FEC设备和可操作以根据接收到的命令信号来接收命令信号并执行影响设施的环境的操作的第二多个FEC设备。 该系统还包括可操作地连接到第一和第二多个FEC装置的控制系统以及可操作地连接到控制系统的控制系统代理。 通常,控制系统从第一多个FEC装置接收数据,并向第二多个FEC装置提供命令信号。 控制系统代理优选地可操作以向管理节点接收和发送SNMP消息,其中所述SNMP消息包括关于控制系统的操作的信息。
