BUILT-IN PROCESS CONTROLLER HAVING POSSIBILITY TO CONTROL CIRCUIT AND VALVE Russian patent published in 2020 - IPC G05B19/42 

FIELD: physics.

SUBSTANCE: invention relates to process units. Built-in regulator configured to operate in field conditions comprises a network interface module for receiving from the remote host a given value for the process parameter and functional modules receiving process parameter measurements data from the field device and executing logic for a control loop, having a field device, based on process parameter measurements and a given value for the process parameter, in order to generate an output signal independently from the remote host. Output signal serves to control the field device. There is also an output module for direct application of the generated output signal in the field device. Network interface module, one or more functional modules and an output module communicate with a first rate. Built-in controller communicates with the remote host at a second rate. First speed is substantially higher than second speed.

EFFECT: improving quickness and efficiency of control.
