A wireless infrastructure node includes at least one processing device configured to receive a data packet from a wireless field device network (WFN) controller, where the data packet includes a network identifier. The at least one processing device is also configured to determine a field device network to receive the data packet based on the network identifier. The at least one processing device is further configured to transmit the data packet to a field device in the field device network. The wireless infrastructure node, the WFN controller, and the field device network comprise one logical WFN among a plurality of logical WFNs. The wireless infrastructure node is one of a plurality of pooled infrastructure nodes configured to communicate between a plurality of WFN controllers and a plurality of field device networks arranged in the plurality of logical WFNs.

System and method for scalable and efficient deployment of wireless infrastructure nodes for multiple collocated wireless field device networks

A method includes receiving first data from multiple wireless field devices at a remote terminal unit. The first data is received using multiple wireless communication protocols. The method also includes executing control logic at the remote terminal unit in order to control at least part of an industrial process. The method further includes communicating second data to the wireless field devices from the remote terminal unit. The second data is transmitted using the multiple wireless communication protocols. In addition, the method includes communicating at the remote terminal unit with a control system, where the remote terminal unit is at least partially controlled by the control system.

Remote terminal unit (RTU) with wireless diversity and related method

A method includes receiving data from multiple wireless field devices using multiple wireless communication protocols. The method also includes normalizing the data from the wireless field devices using one or more templates associated with the wireless field devices. The method further includes transmitting the normalized data in a unified format. The method could also include generating the one or more templates using device description (DD) files associated with the wireless field devices. Each template may provide, for one wireless field device or type of wireless field device, (i) an indication of a type of data provided by the wireless field device or type of wireless field device, (ii) a range of data provided by the wireless field device or type of wireless field device, and (iii) how to normalize data from the wireless field device or type of wireless field device into the unified format.
