Abstract
A field device includes a controller and a process communication module. The controller is configured to perform at least one operation related to process control and is also configured to perform at least one self-recovery operation relative to the field device. The process communication module is coupled to the controller and is configured to couple to a process communication segment and communicate in accordance with a process communication protocol. The controller is configured to detect an erroneous condition and selectively apply the at least one self-recovery operation in response to the detected erroneous condition.
Claims19
A field device comprising:
- a controller configured to perform at least one operation related to process control, the controller also being configured to perform at least one self-recovery operation relative to the field device;
- a process communication module coupled to the controller and configured to couple to a process communication segment and communicate in accordance with a process communication protocol;
- and
- wherein the controller is configured to detect an erroneous condition and selectively apply the at least one self-recovery operation in response to the detected erroneous condition.
A method for operating a field device, the method comprising:
- detecting, in the field device, an erroneous condition;
- determining whether a self-recovery operation stored in the field device is applicable to the erroneous condition;
- and
- selectively applying the self-recovery operation in the field device to recover from the erroneous condition.
