Abstract
A controller for building equipment in a building management system, the controller including a processing circuit configured to receive a field signal from the building equipment on an input port of the controller, determine a type of the field signal, and update a control logic comprising instructions for reading the field signal by tagging within the control logic the input port with the determined type of the field signal.
Claims20
A controller for building equipment in a building management system, the controller comprising a processing circuit configured to:
- receive a field signal from the building equipment on an input port of the controller;
- determine a type of the field signal;
- and
- update a control logic comprising instructions for reading the field signal by tagging within the control logic the input port with the determined type of the field signal.
A method for updating a control logic for a controller in a building management system, the method comprising the steps of:
- receiving, through an input port of the controller, a field signal from a piece of building equipment;
- determining, by the controller, a type of the field signal;
- and
- updating, by the controller, the control logic by tagging the input port with the determined type of the field signal.
A system for updating the control logic of a controller comprising:
- a signal processing unit configured to:
- receive a field signal from an input port of the controller;
- and
- generate a first and second output based on the field signal;
- and
- a processing circuit communicably coupled to the signal processing circuit configured to;
- determine a type of the field signal by comparing the first output voltage and the second output voltage;
- and
- update a control logic comprising instructions for reading sensed data from the field signal by tagging the input port of the controller with the determined type of the field signal.
