A tool is provided for use when replacing devices in an automatically controlled distributed processing system. In one embodiment a network management tool reestablishes all or a portion of the logical connections formerly provided to a bound node where a replacement device is or will be located. The network management tool compares data associated with the logical connections of the bound node and data associated with the logical connections for the replacement device to determine proper logical connection. The network management tool identifies network variables associated with the bound node that are not associated with the replacement device and deletes those network variables from other devices on the network if the network variable is not useful in the network after the replacement device is bound.

System and method for configuring a network after replacing a node

A network tool is provided for use when replacing devices in an automatically controlled distributed processing system. The network tool reestablishes all or a portion of the logical connections formerly provided to the node where the replacement device is or will be located. The tool compares data associated with the logical connections of the node and data associated with the logical connections for the replacement device to determine proper logical connection. In one embodiment, the compared data comprises network variables and configuration properties.

A method of operating a control device having a setpoint value, an error signal, and a control output is disclosed. The error signal is representative of a difference between a controlled variable and the setpoint value, the control output operable to affect the controlled variable. The method includes generating the control output based at least in part on the error signal and holding the control output at a held value independent of the error signal when the error signal is within a dead zone. The method also includes causing an integrating portion within the control device to track the error signal and the held value when the error signal is within the dead zone.

An environmental control system is configured to accept network variable outputs from a plurality of sources on a single network variable input and the update values are stored in a data structure for the computation of control variable values. The system includes a sink controller having a network variable input and a plurality of sources, each having at least one network variable output coupled to the network variable input of the sink controller. A data structure is provided so that update values from the sources may be stored in the structure with reference to the sources that provided the update values. Aggregate values, such as a mean average, minimum value, maximum value, standard deviation, variance, sum, or product may be computed from the values stored in the data structure.

A computer based equipment scheduling system uses activity definition data to schedule equipment. The method may be carried out by a networked computer system that receives activity definition data representing an activity, such as a volleyball game or board meeting, that occurs in a building. This data is stored in a database for use by multiple nodes. The activity definition data may include text or graphical data indicating an activity name, data representing a list of zones that the activity will affect and data representing the mode of possible operation of each building zone affected by the activity. The method also includes assigning zone mode data to the activity data for use in controlling building resources and then automatically controlling the building resources to attain a zone mode of operation assigned to the activity definition data.
