Systems and methods for field device feedback

摘要

The embodiments described herein include a system and a method. In one embodiment, a system includes an industrial controller configured to control a first field device. The first field device includes an actuator and a positioner coupled to the actuator. The positioner is configured to position the actuator. The first field device is configured to detect an undesired condition and to communicate the undesired condition to the industrial controller by using a ReadBack facility of the first field device.

主权项

1. An industrial automation system comprising:
a first field device comprising a Foundation Fieldbus output function block comprising a Readback facility, wherein the first field device is configured to:
receive instructions to implement a SetPoint;detect when an undesired condition related to an external condition of the first field device is present;automatically switch to a Manual mode, an Out of Service mode, or a Local Override mode when the undesired condition is detected to stop the first field device from attempting to implement the SetPoint; andcommunicate a sub-status code/category using a BKCAL_OUT parameter of the Foundation Fieldbus output function block to indicate occurrence of the undesired condition; and an industrial controller communicatively coupled to the first field device, wherein the industrial controller is configured to:
communicate the Setpoint to the first field device;receive the sub-status code/category from the first field device; andadjust operation of the industrial automation system based at least in part on the sub-status code/category.
