A wireless device manager is configured to function as a gateway for at least one industrial wireless network. The gateway is associated with at least one industrial wireless network protocol; and the wireless device manager comprises a first radio module configured to communicate directly with one or more devices over a distance of at least about two kilometers using a long-range wide area network protocol.
Abstract:
A method includes transmitting, over a virtual private network (VPN) to a remotely-located control platform, a request for first information associated with a BOOTP protocol synchronization process. The method also includes receiving, from the control platform, a first response comprising the requested first information. The method further includes receiving, over a local network from an embedded device in a distributed control system, a request for second information associated with the BOOTP protocol. In addition, the method includes transmitting, to the embedded device, a second response comprising the requested second information.
Abstract:
A system includes at least one industrial control and automation field device and a remote terminal unit (RTU). The RTU includes input/output (I/O) terminals configured to be coupled to the field devices. The RTU also includes one or more I/O modules having one or more reconfigurable I/O channels configured to be coupled to the I/O terminals. Each reconfigurable I/O channel is configurable as an analog input, an analog input supporting digital communication, an analog output, an analog output supporting digital communication, a digital input, a digital output, and a pulse accumulator input. The RTU further includes at least one processing device configured to control a configuration of each of the one or more reconfigurable I/O channels.
Abstract:
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.
Abstract:
A security appliance to perform a method that includes receiving a first set of data from a first device using a first secure protocol of a first network, the first secure protocol comprises a first level of security, and determining, by the security appliance, that the received first set of data is intended for a second device on a second network using a second secure protocol, the second secure protocol comprises a second level of security different from the first. The method includes authenticating, by the security appliance, the received first set of data from the first network using the first secure protocol for transmission through the second network using the second secure protocol while collecting and concentrating additional data from the first network and transmitting, by the security appliance, the received first set of data to the second device via the second network comprising the second secure protocol.
Abstract:
A gateway is configured to perform a method that includes receiving data from a first device using a first protocol. The first protocol is a cloud based protocol. The method also includes determining that the received data is intended for a second device that uses a second protocol. The method further includes converting the received data from the first protocol to the second protocol. In addition, the method includes transmitting the received data to the second device via the second protocol.
Abstract:
A method includes transmitting a notification to an end-user device, where the notification identifies an event in an industrial process control and automation system. The method also includes obtaining contextual information associated with the event, where the contextual information includes one or more types of additional information associated with the event. The method further includes transmitting the contextual information to the end-user device. In addition, the method could include receiving a request for the contextual information from the end-user device, where the contextual information is transmitted to the end-user device in response to the request. The contextual information could be obtained from multiple devices or systems automatically in response to the request.
Abstract:
A method includes receiving information identifying multiple events in an industrial process control and automation system and routing the events to one or more subscribers, where the one or more subscribers include a notification system. The method also includes translating the events into notifications using the notification system and transmitting each notification for delivery to one or more mobile end-user devices. The method could further include identifying multiple rules, where each rule defines at least one condition and at least one action. Each condition is associated with at least one event, and each action is associated with information related to the at least one event. In addition, the method could include determining whether the at least one condition of each rule is satisfied based on the information identifying the multiple events, where the notifications are generated based on each rule whose at least one condition is satisfied.
Abstract:
A redundant process controller arrangement includes a primary controller and parallel connected secondary controller each coupled to actuators and sensors coupled to processing equipment. The primary and secondary controllers include a main writable memory including a cache data control algorithm, central processing unit (CPU) with cache memory including cache not supporting write-thru, tracker logic coupled to a control cycle database in a tracked memory region and to a primary tracking buffer. A redundancy link is between the CPUs for passing tracked changes. The algorithm implements memory tracking using copy-back including the primary tracker logic each cycle writing tracked changes into the primary tracking buffer, and at cycle end, transferring tracked changes from the primary tracking buffer to the secondary controller over the redundancy link, and writing tracked changes to the secondary control database.

An apparatus includes a first interface configured to communicate over a first industrial process control network using a first protocol. The apparatus also includes a second interface configured to communicate over a second industrial process control network using a second protocol. The apparatus further includes a third interface configured to communicate with at least one supervisory device over a third network.
