Abstract: A communication interface apparatus in a tank gauging system. The communication interface includes a memory and a processor couple to the memory. The processor communicates using a control application with a tank inventory system that operates over a serial connection; and communicates using a wireless application with tank gauging equipment that operates over a wireless connection.

Abstract: Methods, systems and devices for OTAP (Over the Air Provisioning) of WirelessHART (Highway Addressable Remote Transducer) devices. A unique system level setting can be provided for enabling over the air provisioning of WirelessHART devices in a WirelessHART network having one or more field device access points. Each field device access point can be configured to be enabled/disabled to advertise in a specific WirelessHART network ID in association with a target WirelessHART network ID with respect to the WirelessHART network. A join key is provided in association with a new WirelessHART network ID to which at least one field device access point among the plurality of field device access points needs to be advertised along with a time limit, thereby enabling provisioning of the WirelessHART devices to a target wireless network, wherein the target WirelessHART network ID and the join key are written with respect to a new WirelessHART device. The new WirelessHART device can be then restarted.

Abstract: A method for bandwidth management in a wireless network having wireless field devices (FDs) wirelessly coupled to a wireless access point associated to a wireless gateway. A first bandwidth usage percentage (BUP) consumed by the wireless access point and wireless router(s) is calculated from summed connected device weights. In response to a new FD or wireless router requesting to be connected to the network, a second BUP is calculated that would be consumed by the wireless access point and the wireless router(s) if the new FD or wireless router were connected to the wireless network. If the second BUP is not less than respective BUP thresholds, the new FD or router is prevented from being connected to the network. Disclosed bandwidth management can also be applied if an already connected FD in the network changes its path from one router or access point to another connected router or access point.
