Abstract: A method of providing a plurality of controller certificates for a plurality of controllers within a Building Management System (BMS) includes downloading project information defining the BMS and using the downloaded project information to solicit a Certificate Signing Request (CSR) from each of the plurality of controllers of the BMS. The received CSRs are uploaded to a remote server so that the remote server can generate a corresponding controller certificate for each of the plurality of controllers of the BMS. The generated controller certificates are then downloaded to the corresponding one of the plurality of controllers of the BMS.

Abstract: A building management system, such as a small or medium business, having one or more control devices. Assigning codes to devices, and reading and listing them may aid in configuring the devices. Templates may be used for dynamic configuration of devices and equipment. Representing terminal assignments and wiring diagrams of control devices may be intuitive in that they resemble real hardware for ease of complete installation. The present system and approach may provide an intuitive way of securely registering devices with cloud usage, for example, involving a mobile phone with no manual entry of data so that a user can complete this process with ease. An intuitive, automatic and asynchronous device configuration downloading may be seen, such as to multiple control devices in a single shot. There may be seamless configuration data synchronization, for example, in view of replacement devices, or so the latest data is readily available.

Abstract: A first building equipment to be controlled by a building controller is selected via a user interface from a plurality of predefined building equipment options and a first control loop for controlling the first building equipment is defined via the user interface by selecting from a plurality of predefined first control loop parameter options and one or more terminals of the building controller are assigned to the first control loop. A second building equipment to be controlled by the building controller is selected via the user interface from the plurality of predefined building equipment options and a second control loop for controlling the second building equipment is defined via the user interface by selecting from a plurality of predefined second control loop parameter options. One or more terminals of the building controller are assigned to the second control loop.

Abstract: A first image of an electronic device is captured and processed in order to identify the electronic device. After identifying the electronic device, information is downloaded to a mobile device including specific wiring instructions for connecting the electronic device, which are superimposed onto an image of the electronic device to guide a user of the mobile device in wiring the electronic device. A second image of an at least partially wired electronic device may be captured and processed to ascertain whether there are any wiring errors. When wiring errors are found by the remote server, the mobile device receives a message from the remote server indicating the wiring errors that were found.

Abstract: A method of configuring an HVAC system uses a Specifier Library including specifier options for a plurality of HVAC components and a Shapes Library including a plurality of representative Shapes. An engineering tool accepts a selection from a user of an HVAC component and automatically loads one or more Shapes from the Shapes Library into a configuration project, the one or more Shapes corresponding to the user-selected HVAC component. The engineering tool displays one or more options for the selected HVAC component and accepts selections of one or more options by the user. The engineering tool automatically loads additional Shapes from the Shapes Library into the configuration project, the additional Shapes corresponding to one or more of the accepted selections of the one or more options and combines the loaded Shapes within the configuration project to automatically generate a graphical representation of the HVAC system.

Abstract: A method of configuring an HVAC system uses a Specifier Library that includes specifier options for a plurality of HVAC components. An engineering tool accepts a user selection of an HVAC component that will be part of the HVAC system and displays one or more options for the selected HVAC component. The engineering tool accepts selections of one or more options by the user and creates one or more points for the selected HVAC component based on the user selections, each of the one or more points having one or more point parameter values. The engineering tool creates a configuration package to configure a controller based at least in part on the user selections and the one or more points and downloads the configuration package to at least partially configure the controller. At least part of the HVAC system is controlled using the controller.

Abstract: A tool for an approach and mechanism for calculating and configuring memory mapping of trend log objects in a system, such as an HVAC. It may incorporate determining available memory of a controller for trending a unit of equipment of a system. A calculation of available records may be made for configuring and using a trend. The calculation may be made in view of the controller memory and parameters including buffer size, log interval and retention time. A change in parameters may cause a recalculation of available records. The “available record” terms may be regarded as being in a user-understandable format. The format may be intuitive. Anomalies of trends of equipment may lead to spotting issues of the equipment.

Abstract: An approach and mechanism for improving reliability, performance and on time execution of critical operations of a system, such as an HVAC. A controller may have two or more processing cores. One core may be dedicated to execution of critical operations of a system. Another core may be dedicated to less- or non-critical operations of the system. For instance, if there are delays relative to the less- or non-critical operations, these delays may be ineffective relative to the processing of critical operations.
