UCO – SERIAL COMMANDER 300

Abstract

UCO - Serial Commander 300 (UCO-SC300) is an open-source Graphical User Interface (GUI) developed to monitor ABB's Commander 300 universal process controller. Communication is established through the RS422/485 standard via the serial communication expansion module for the Commander 300. This application provides the user with the appropriate tools to view and save process variables and controller parameters, change the operation mode (manual/automatic) or set the desired value of the control signal in manual mode or the setpoint value in automatic mode. The application is simple as its main function is monitoring and data logging, leaving all the configuration of the C300 controller to be done from its button panel. Only the functionality to modify the control signal or the reference has been added to the application so that experiments can be done where a pure step jump is applied to these signals, which would be very difficult with the up/down arrow buttons of the Commander 300.
