Methods and systems for subscribing remote devices to process control data

A method of securely subscribing a remote computing device to obtain process data from a process control system of a process plant, comprising:

• receiving, at a mobile server via a first network from a data server, configuration data indicating a configuration of the process control system;
• establishing, by the mobile server, a communication connection with the remote computing device via a second network;
• receiving, at the mobile server via the second network from the remote computing device, an indication of a view list requesting process data associated with the process control system, wherein the process data corresponds to available data indicated by the configuration data;
• receiving, at the mobile server via the first network from the data server, a polling request for a list of data to be sent from the data server to the mobile server;
• determining, by the mobile server, the list of data based at least in part upon the view list;
• sending, from the mobile server to the data server via the first network, the list of data in response to the polling request;
• receiving, at the mobile server via the first network from the data server, a plurality of data values associated with the list of data;
• and
• sending, from the mobile server to the remote computing device via the second network, a view set containing at least some of the plurality of data values corresponding to the view list associated with the remote computing device.
