A networked system having a wide variety of applications and particularly applicable to facilities management systems has multiple levels of software in processing nodes. The levels include a 'features' processing level which communicates requests for data to a software object level containing databases of processes and attributes and database managers. The database managers in the software object level operate to provide data to the high level features in the same format. The software object level communicates with a hardware object level which also contains databases and database managers to mask differences between operational hardware units. By categorizing operational units by type, additional units of a known type can be added with only low level hardware object database changes. Adding units of a new type is facilitated by software changes confined to the lower level hardware and software objects, avoiding software changes at high level features. Individual software objects are tailored for typical types of inputs and output devices encountered by facilities management systems. Universal drive circuitry also provides applicability to a broad range of devices.

After being shed to limit energy consumption, software local to the node restores the loads under predefined circumstances independently of the load shed commands to achieve distributed load management.

Universal drive circuitry also provides applicability to a broad range of devices. An optical isolator is connected between signal line outputs from a node and a line driver connected to a pair of lines on a bus. Similarly, an optical isolator is connected between signal line receiving inputs and a line receiver. The signal lines can be biased to predetermined levels to reduce node sensitivity to noise.

Universal drive circuitry also provides applicability to a broad range of devices. Nodes are provided with ports which may accommodate a non-configured device. When a non-configured device is identified on a port, a drop identifier specifying the port is transmitted to the non-configured device for use in establishing a network address by which the non-configured device can be accessed.

Periodically each node transmits its time stamp. When a node receives a time stamp later than its own, the receiving node requests the transmitting node to transmit its data base to update the receiving node with the earlier time stamp.

A network system having a wide variety of applications and particularly applicable to facilities management systems includes network controllers which continuously process data related to building and industrial, environmental, security and other automated system controls. Each network controller has a network address indicative of a communication link to which the network controller is connected, a local address and a node drop ID to determine whether the network controller is a configured or non-configured device. Data stored in an archive device is downloaded to a destination network controller in the absence of a routing table in the destination network controller by transmitting a download request message from the archive device to an intermediate network controller with a routing table. The intermediate network controller assumes control of the download request by transmitting the message to the destination controller. The destination controller acknowledges receipt of the message by transmitting an acknowledge message back to the intermediate network controller, which passes the acknowledge message to the archive device in accordance with the routing information stored in the intermediate network controller. Thus, as certain network controllers are connected, disconnected or disabled during the operation of the network, the control of a process is not interrupted. Additionally, the network controllers are not configured to store large amounts of routing data because a path to a device can be established through other controllers with routing information.

An arrangement monitors the values at sensors such as temperature sensors which each generate a voltage value related to the particular sensor temperature. The arrangement produces a digital value representative of the temperature at each sensor, wherein errors caused by fluctuations in the temperature of the arrangement circuitry and aging are reduced toward zero. The arrangement corrects for errors for a wide range of combinations of sensor temperatures and temperature fluctuation in the circuitry of the arrangement. The arrangement includes separate channel circuitry associated with each sensor and temperature independent references associated with each sensor type. Generally, to provide error correction, the arrangement uses stored comparison values to correct for channel-to-channel circuitry differences and stored values associated with the independent references to correct for temperature fluctuation and aging of the arrangement.
