1. 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 an asset management system (AMS) different from the DCS and communicatively coupled to at least one of the controller or field device of the DCS comprising:
a DCS workstation adapted to communicate with the at least one controller and one field device of the DCS;
an AMS workstation adapted to communicate with the at least one controller and one field device of the DCS independently of the DCS;
a non-transitory computer-readable memory including a set of computer-executable instructions communicatively coupled to the AMS workstation and the DCS workstation, adapted to:
intercept a parameter change command for a process control device originating from the AMS workstation, wherein the parameter change command includes instructions to modify at least a set of critical parameters of the process control device;
transmit a warning message to the DCS workstation indicating that a parameter change command for the process control device is intercepted, wherein the warning message contains a set of warning parameters including at least a user identifier, a plant device identifier, and the set of critical parameters of the process control device to be modified by the parameter change command;
receive a response from the DCS workstation indicating whether to allow the parameter change command to modify the set of critical parameters of the process control device;
release the intercepted parameter change command if the response to modify the set of critical parameters is allowed; and
otherwise terminate the instructions to modify the set of critical parameters.
