ABSTRACT:
A node having an on-board microprocessor and circuits to perform a particular function in an analytic instrument system having a CANBUS and using distributed logic to control the various analysis functions, including data acquisition, system control, and data transition. The various node circuits and functions include generating a signal to control a motor by pulse width modulation and feedback, control of temperature for sample and reagent reactions (incubations), monitoring the status of instrument control panel switches and visual indicators, voltage sources, test sample location, processing calorimeter measurements, and the like. Each node includes a CAN interface and a reset circuit, which is responsive to the system controller for performing the specific node function and responding to controller commands. The reset circuit allows for reinitializing the node microcontroller on, e.g., system startup, or on demand from the system controller or any other node on the CANBUS.
