Abstract
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.
