Embodiments of the present invention provide a system and method of providing analog setpoints that eliminate, or at least substantially reduces, the shortcomings of prior art analog setpoint systems and methods. One embodiment of the present invention includes a method of multiplexing analog setpoints comprising transmitting the analog signal to a plurality of target devices, wherein the analog signal represents multiple setpoints, transmitting a first setpoint indicator separate from the analog signal to indicate to a first target device that a first setpoint for the first target device is being represented by the analog signal, saving a first setpoint value asserted by the analog signal at the first target device in response to the first setpoint indicator.
