Abstract
A system validates critical parameter changes in a DCS by intercepting commands, transmitting warnings, receiving responses, and releasing commands if allowed. A method involves intercepting parameter change commands, transmitting warnings, receiving responses, and releasing commands if responses allow. A non-transitory computer-readable medium causes a computer to intercept commands, transmit warnings, receive responses, and release commands if allowed.
Claims20
A system for validating critical parameter changes to a device in a distributed process control system (DCS) including at least one controller and one field device and having a second system different from the DCS and communicatively coupled to at least one of the controller or field device of the DCS via a common communication network comprising:
- a non-transitory computer-readable memory including a set of computer-executable instructions communicatively coupled to the second system and the DCS via the common communication network and adapted to:
- intercept a parameter change command for a process control device originating from outside the DCS, wherein the parameter change command includes instructions to change at least a set of critical parameters of the process control device;
- transmit a warning message to a DCS workstation wherein the warning message indicates that a parameter change command for a process control device of the DCS is intercepted;
- receive a response from the DCS workstation indicating whether the critical parameter changes to the process control device is allowed;
- and
- release the intercepted parameter change command if the response to the critical parameter changes is allowed.
A computer-implemented method for validating critical parameter changes to a device in a distributed process control system (DCS) including at least one controller and one field device and having a second system different from the DCS and communicatively coupled to at least one of the controller or field device of the DCS via a common communication network, the method comprising:
- intercepting a parameter change command for a process control device originating from outside the DCS, wherein the parameter change command includes instructions to change at least a set of critical parameters of the process control device;
- transmitting a warning message to a DCS workstation wherein the warning message indicates that a parameter change command for a process control device of the DCS is intercepted;
- receiving a response from the DCS workstation indicating whether the critical parameter changes to the process control device is allowed;
- and
- releasing the intercepted parameter change command if the response to the critical parameter changes is allowed.
A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed, cause a computer to:
- intercept a parameter change command for a process control device originating from outside the DCS, wherein the parameter change command includes instructions to change at least a set of critical parameters of the process control device;
- transmit a warning message to a DCS workstation wherein the warning message indicates that a parameter change command for a process control device of the DCS is intercepted;
- receive a response from the DCS workstation indicating whether the critical parameter changes to the process control device is allowed;
- and
- release the intercepted parameter change command if the response to the critical parameter changes is allowed.
