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.
Claims17
A field device comprising:
- a controller configured to perform at least one operation related to process control, the controller also being configured to selectively 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;
- wherein the controller is configured to generate a notification in response to a detected erroneous condition related to the field device, and wherein the notification includes a request to authorize self-recovery;
- wherein the controller is configured to automatically perform the at least one self-recovery operation on the field device in response to a reply to the request;
- and
- wherein the controller is configured to transmit an indication relative to whether the at least one self-recovery operation was successful and perform an operator determined recovery method if the at least one self-recovery operation was not successful.
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;
- transmitting an indication of the erroneous condition over a process communication segment and requesting authorization to apply the self-recovery operation;
- performing automatically the self-recovery operation if an authorization to apply the self-recovery operation is received by the field device;
- transmitting an indication relative to whether the self-recovery operation was successful;
- and
- manually performing an operator determined recovery method if the self-recovery operation was not successful.
A method for operating a field device, the method comprising:
- detecting, in the field device, an erroneous condition;
- identifying a self-recovery operation stored in the field device applicable to the erroneous condition;
- transmitting an indication of the erroneous condition over a process communication segment and requesting authorization to apply the self-recovery operation;
- authorizing the field device to apply the self-recovery operation;
- performing automatically the self-recovery operation;
- transmitting an indication as to an unsuccessful outcome of the self-recovery operation;
- identifying manually a recovery method applicable to the erroneous condition;
- and
- performing manually the recovery method.
