'' INTERFACE BETWEEN A COMMUNICATIONS NETWORK AND A PROCESS CONTROL SYSTEM, SOFTWARE PROGRAM IMPLEMENTING AN INTERFACE BETWEEN A COMMUNICATION NETWORK AND A PROCESS CONTROL SYSTEM FOR RUNNING ON A PROCESSOR, MANUFACTURING ARTICLE IMPLEMENTING AN INTERFACE PROGRAM SOFTWARE BETWEEN A COMMUNICATIONS NETWORK AND A PROCESS CONTROL SYSTEM FOR EXECUTION ON A PROCESSOR, AND, ADAPTED INTERFACE IN ORDER TO BE COUPLED BETWEEN A REMOTE COMMUNICATIONS NETWORK AND A PROCESS CONTROL SYSTEM ''. An interface between a remote communication network and a process control system includes a storage device, a communication software stack and a user software layer. The user software layer allows the interface between the remote communications network and the process control system directed to the stack of communication software to operate in the process control system using a process communication protocol, by monitoring traffic. the communication software stack, and by copying requested message traffic to the storage device. The user software layer also includes the interface software that allows access to the storage device over the remote communications network to thereby distribute the data to a device connected to the remote communications network.
