A system for configuring a controller without a file transfer. Programmable controllers may typically use configuration data structures that are transferred to the controller via a file transfer mechanism. The present controller does not necessarily need a tool with file transfer capability, but only a capability to read and write network variables. Configuration data structures may incorporate replacement specifications, and replacement constants representing replacement data to be selected. Changes of value in public variables may be identified as being replacement variables by virtue of their presence in the replacement specifications. When such changes of values are detected, instructions in the replacement specifications may detail how to modify the configuration file content associated with those public variables.

System for configuring a controller

A wall module user interface having a memory with a table driven structure. The structure may incorporate an objects table subject to a dynamic object table capable of rendering display objects such as labels or button icons based on arbitrary comparison conditions against the value of a variable at run time. Also, the structure may incorporate a screen actions table subject to a dynamic actions table to similarly determine an action of the user interface based on arbitrary comparison conditions against the value of a variable. An action may be, for example, going to a next screen, where the next screen is determined by the value of the variable at run time.

Flexible fixed-content dynamically changeable wall module user interface

A system having a function block execution framework. Function blocks may be for use in a control system design. These blocks may be selected from a library of a function block engine. Selected function blocks may be executed for operational purposes. They may be continuously executed by a processor to maintain operational status. However, since a function block engine and a resulting system of function blocks may be operated with battery power, executions of function blocks may be reduced by scheduling the executions of function blocks to times only when they are needed. That means that the processor would not necessarily have to operate continuously to maintain continual execution of the function blocks and thus could significantly reduce consumption of battery power.

A configuration tool for a programmable HVAC controller is provided. The configuration tool may accept user input, and may generate a corresponding configuration profile based on the user input. The configuration profile may be downloaded to a programmable HVAC controller, which may, among other things, reconfigure the I/O terminals of the programmable HVAC controller. The configuration tool may generate a terminal diagram that labels at least some of the I/O terminals of the programmable HVAC controller based on the particular configuration profile. In some cases, the configuration tool may output the terminal diagram in a format that can be printed on a label, with the label being suitable for adhering to the programmable HVAC controller.

Configurable HVAC controller terminal labeling

A changeable BACnet interface system having a workstation and a controller. The system may allow a controller object interface to be engineered and downloaded to the controller via configuration files, rather than as individual objects created at run time. A BACnet network may be connected to the workstation and controller. BACnet objects may be designed to constitute an interface to the control application, and be stored in the controller. The BACnet interface may be presented to the BACnet network.

Changeable BACnet interface

A system for interfacing information between subsystems of an embedded software system with subsystem independence. It is a public variable system that defines a simple, extensible framework for interfacing between product subsystems such as control engines, input/output subsystems, and communications protocols. Server subsystems within the embedded software system are given the ability to make public information available for use by client subsystems within the system, with isolation between client and server subsystems.

Public variable interface system

Systems, apparatuses and methods for timing access to a shared communications bus by a plurality of devices. Each of a plurality of nodes is successively provided an opportunity to gain access to a shared bus according to a time slot allocation referenced from a time reference. The successive time slot allocation occurs until one of the nodes has a message to send via the shared bus. The node that has the message to send transmits a frame onto the bus. A new time reference is established at each of the nodes based on an indication provided by the transmitted frame, whereby each of the nodes can then be afforded a new opportunity to gain access to the shared bus according to the time slot allocation referenced from the new time reference.

A distributed environmental/load control system comprising a thermostat operable to supply signals indicative of sensed and desired values of a parameter in an environmentally controlled space to a first controller operable to control condition changing equipment for regulating the parameter, the signals being transmitted over a communications link between the thermostat and first controller. A second controller which is operable to control a plurality of loads in accordance with predetermined criteria to limit energy consumed by the loads is connected to the communications link through an interface device operable to process the signals produced by the thermostat in response to instructions furnished by the second controller and to supply the processed signals to the first controller.

Distributed environmental/load control system

An asynchronous one way digital data communication system is disclosed in which a first microcomputer produces a series of groups of pulses at a first port representative of digits in an information packet to be transmitted, the groups being separated by strobe pulses at a second port. The pulses drive switches in two current paths to control current therethrough supplied by a receiver module including a second microcomputer having a serial input port connected to an internal counter and an interrupt port. Current detectors supply pulses corresponding to currents in the paths to the serial input and interrupt ports, from which the second microcomputer reproduces the information packet.
