1. A method of data synchronization between a portable field maintenance tool and a process control asset management system application within a process control system, the method comprising:

  • automatically transferring, by the portable field maintenance tool, a set of data to a portable field maintenance tool communication server within the process control asset management system via a wireless communication channel of the process control asset management system in response to a change in the set of data, wherein the process control asset management system is communicatively coupled to a field device via a digital process communication channel, wherein the set of data is defined by a set of rules for automatic synchronization of the set of data between the portable field maintenance tool and the process control asset management system application during a communication session between the portable field maintenance tool and the process control asset management system application, wherein the portable field maintenance tool and the portable field maintenance tool communication server each have a framework of a communication protocol of the field device layered above a communication protocol of the process control asset management system, and the protocol of the process control asset management system layered above a network communications protocol, and wherein the set of data is wrapped in the communication protocol of the process control asset management system;

    notifying, by the portable field maintenance tool communication server in response to the automatic transfer of the set of data, the process control asset management system application that the set of data from the portable field maintenance tool communication server is ready to synchronize with the process control asset management system application;

    initiating, by the process control asset management system application in response to the notice, a transfer of the set of data from the portable field maintenance tool communication server to the process control asset management system application to synchronize a set of the data in the process control asset management application with the set of data from the portable field maintenance tool;

    publishing, by the process control asset management system application in response to a completion of the transfer of the set of data, a user interface update message to a plurality of process control asset management system stations that the set of data has changed;

    refreshing, by the user interface on one or more of the plurality of process control asset management stations, a display view affected by the change in the set of data; and

    executing, by the process control asset management system, an operation of the process control system involving the change in the set of data.
