The Commander C200 single loop controller was launched in 1992. It enabled control of a single PID loop using a number of control outputs (for example, analog, digital or relay). The standard C200 was available with auto tune and advanced versions were available with ramp / soak profiling and flow totalizing capabilities.
In December 1998, the C200 was superseded by the C350 universal process controller, which in turn was superseded by the ControlMaster CM30 universal process controller. The CM30 uses ABB’s common instrumentation platform HMI and features a new, full color TFT display enabling both control loops in the new dual control template to be displayed simultaneously in a single operator view. The CM30 also features ethernet communications, profile control and bank control functionality as well as the features previously available on the C200. All features are accessible via the front panel of the controller without the need for PC configuration software.
