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; and
communicate 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; and
adjust operation of the industrial automation system based at least in part on the sub-status code/category.

Abstract
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.

11. A method, comprising:
-
determining, using a processor of a field device, whether an undesired condition related to an external condition of the field device is present; and when the undesired condition is detected; instructing, using the processor, the field device to automatically switch to a Manual mode, an Out of Service mode, or a Local Override mode to stop the field device from attempting to implement a SetPoint received from a control function block of an industrial controller; determining, using the processor, a first sub-status code/category, wherein the sub-status category is configured to indicate presence of the undesired condition; and instructing, using the processor, a Foundation Fieldbus output function block of the field device to communicate the first sub-status code/category to the control function block using a BKCAL_OUT parameter of Foundation Fieldbus output function block to enable the control function block to adjust operation of an industrial automation system comprising the field device based at least in part on the sub-status category. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory tangible computer-readable medium configured to store a plurality of instructions executable by a processor of a field device, wherein the instructions comprise instructions to:
-
determine, using the processor, whether an undesired condition related to an external condition of the field device is present; when the undesired condition is detected; instruct, using the processor, the field device to automatically switch to a Manual mode, an Out of Service mode, or a Local Override mode to stop the field device from attempting to implement a SetPoint received from a control function block of an industrial controller; determine, using the processor, a sub-status code/category, wherein the sub-status category is configured to indicate occurrence of the undesired condition; and instruct, using the processor, a Foundation Fieldbus output function block of the field device to communicate the sub-status code/category to the control function block using a BKCAL_OUT parameter of Foundation Fieldbus output function block to enable the control function block to adjust operation of an industrial automation system comprising the field device based at least in part on the sub-status code/category. - View Dependent Claims (17)
