Description

TECHNICAL FIELD The present disclosure relates to building controllers, and more particularly, to building controllers having programmable wiring terminals. BACKGROUND Many controllers, including building controllers, are produced having fixed communication ports and fixed I/O control terminals. If all of the communication ports or I/O control terminals are used up, and the user wants the controller to be part of an additional network, or wants additional I/O control terminals, the user is required to add additional equipment such as an additional building controller. This can make the installation process expensive and complicated. In some cases, a building controller may have unused communication ports even though all of the I/O control terminals are used. A building controller may have unused I/O control terminals even though all of the communication ports have been used. What would be desirable is a building controller that allows a user to use unused communication ports as I/O control terminals, and/or to use unused I/O control terminals as communication ports. What would be desirable is a building controller having a plurality of wiring terminals that can be programmed to function as either communication ports or as I/O control terminals, depending on the need. SUMMARY This disclosure relates to building controllers, and more particularly, to building controllers having programmable wiring terminals. An example may be found in a building controller that includes a housing and a plurality of wiring terminals that are secured relative to the housing and are physically accessible from outside of the housing. A controller is housed by the housing and is operatively coupled to the plurality of wiring terminals. The controller is field programmable to set each of two or more of the plurality of wiring terminals to a particular one of a plurality of wiring terminal types including an input wiring terminal type, an output wiring terminal type, and a communication wiring terminal type where the communication wiring terminal type is configured to operate in accordance with a predetermined communication protocol. Another example may be found in a method for programming a building controller. The example method includes displaying on a display a representation of each of a plurality of wiring terminals of the building controller. A wiring terminal type selector for each of two or more of the plurality of wiring terminals of the building controller is displayed on the display. At least some of the wiring terminal type selectors allow a user to select between an input wiring terminal type, an output wiring terminal type, and a communication wiring terminal type for the corresponding wiring terminal of the building controller. A functionality of each of the two or more of the plurality of wiring terminals of the building controller is then programmed based on selections made by the user via the wiring terminal type selectors. Another example may be found in a method that includes setting each of a plurality of wiring terminals of a building controller to a particular one of a plurality of wiring terminal types including an input wiring terminal type, an output wiring terminal type, and a communication wiring terminal type. Two or more of the plurality of wiring terminals are set to the communication wiring terminal type and are associated with a first predetermined communication protocol, and two or more of the plurality of wiring terminals are set to the communication wiring terminal type and are associated with a second predetermined communication protocol different from the first predetermined communication protocol. The example method includes receiving one or more first communication messages via the two or more of the plurality of wiring terminals associated with the first predetermined communication protocol over a first communication bus and translating the one or more first communication messages received over the first communication bus to the second predetermined communication protocol, resulting in one or more first translated messages. The one or more first translated messages may be routed to and communicated over a second communication bus via the two or more of the plurality of wiring terminals associated with the second predetermined communication protocol.
