ABSTRACT:
A controller assembly is adapted for regulating at least one valve having a valve positioner. The controller assembly comprises a digital controller having a plurality of data inputs and data outputs and includes at least one proportional-integral-derivative (PID) controller operative to modulate the valve positioner in response to data received at the data inputs. The digital controller is configured to perform the following functions within a total time period of no greater than 10 ms: acquisition of data at the data inputs, processing of the data, and transmission of data from the data output in order to regulate the valve(s). The digital controller may include a quantity of at least sixteen digital inputs, at least sixteen digital outputs, at least eight analog inputs and at least eight analog outputs.
