An integrated controller configured to operate in a field includes a network interface module, one or more function modules, and an output module. The network interface module is configured to receive, from a remote host via a communication link, a setpoint for a process variable. The one or more function modules are configured to (i) receive a measurement of a process variable from a field device and (ii) execute logic for a control loop including the field device based at least in part on the measurement of the process variable and the setpoint for the process variable, to generate an output signal independently of the remote host, where the output signal is for controlling the field device. The output module is configured to directly apply the generated output signal to the field device.

Integrated process controller with loop and valve control capability

A liquid level control loop optimizer receives a selection of a vessel configuration and a variety of parameters specifying the vessel dimensions, the fluid type(s), and the flow parameters of the liquid level control loop. The optimizer also receives a selection of various valve and actuator options and determines a variety of available configurations based on the selected options. The optimizer simulates each of the available configurations under the conditions specified by the parameters, and determines control loop characteristics and/or properties based on the simulations. The optimizer may display and/or rank the various configurations to assist a user in selecting a configuration that best meets the requirements of the control loop.
