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.
Claims20
A system comprising:
- an industrial controller configured to control a first field device;
- the first field device comprising:
- an actuator;
- a positioner coupled to the actuator and configured to position the actuator, wherein 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.
A method, comprising:
- determining a state of a field device;
- deriving a first indication of an undesired condition if the state includes an undesired condition, then;
- adding the first indication of the undesired condition to a ReadBack facility;
- and
- communicating the first indication to a control block.
A non-transitory tangible computer-readable medium storing a plurality of instructions executable by a processor of an electronic device, the instructions comprising:
- instructions to determine a state of a field device;
- instructions to derive an indication of an undesired condition if the state includes an undesired condition, then;
- instructions to add the indication of the undesired condition to a ReadBack facility;
- and
- instructions to communicate the indication to a control block.
