Tools and techniques are described to attach a device to a controller, whereby the controller analyzes the device inputs, looks up information about the device in a database, and then determines which inputs on the device match the defined device inputs. It then may translate information received from the device into an intermediate language. It may also use the information received from the device, the location of the device, and information about the device to create a digital twin of the device.

An interface is disclosed that allows a controller wiring diagram to be automatically created by understanding the nature of the building the controller is in as well as understanding the nature of the devices that are to be wired to it, and the location within the building of the devices. Users, using the user interface, can modify a depiction of the wiring diagram which may further modify the hardware of the controller device interface. Some embodiments further comprise modules that plug into the controller. The modules comprise the device connector that will be wired to the device. Some modules have hardware and memory that allow the module to physically modify the device connectors.

Tools and techniques are described to automate creation of point mapping diagrams between controllers and controlled resources. After receiving a defined space diagram (which may be input using a graphical interface of the controller, or by other means), resource locations and resource wiring requirements (which may be done automatically), a wiring diagram including point mapping between the resources and any necessary controllers is generated. If resources need to be moved, a new wiring diagram and/or point mapping can be regenerated.

Tools and techniques are described to create a controller wiring board. A user, using a user interface associated with a controller, can determine which devices will be attached to a controller. The features of the devices may be already known by the controller. The controller can change wiring terminal types depending on the requirements of the devices wired to the controllers. In some embodiments, a device is wired to a module associated with the controller. The controller can signal to the module to modify its wiring terminal to match the needs of the device to be wired to that location.

Tools and techniques are described to automate line testing when wiring devices (such as equipment and sensors) to controllers. Controllers have access to databases of the devices that are controlled by them, including wiring diagrams and protocols, such that the controller can automatically check that each wire responds correctly to stimulus from the controller. After testing, a reporting device rapidly shows the results of the line testing.

A controller is described that a building design can be input into, the building design comprising inputting a layout, predefined resources and positions for resources. within the layout. The resources may have a predefined physics nature that includes physics equations, allowable inputs and outputs, etc. The system then can determine how many controllers are needed of what type, and create a guided wiring system. In some implementations a user can control certain aspects of the wiring system, such as how full the individual controllers are and how much money is to be spent on labor versus money spent on equipment.
