A method and system of communicating between a wireless network and a process control system communicatively coupled to a server, such as OPC. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via a process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and written to the corresponding input/output data point.

System for merging wireless data into an established process control system

A method and system of communicating between a wireless network and a process control system communicatively coupled to a server via a process control system interface, such as OPC or a proprietary API. The wireless network may be a mesh network and the server may be a mesh server. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via the process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and the mapped process control data is written to the corresponding input/output data point.
