Parties having different responsibilities and interests at a monitored location can be given a partial view of the totality of the sensor channels of data generated by the various sensors installed at the monitored location. The partial views deliver customized sets of data streams to customers. The selective distribution of sensor information accommodates the divergent interests and needs of parties responsible for tracking the various characteristics of a monitored location.

The presentation of sensor network information can be provided to a user via a customized dashboard web interface. The dashboard web interface can be based on customized transformation and alert functions that can be applied to one or more sensor channels of data produced from sensors at a monitored location. The customized alerts can provide real-time monitoring of targeted conditions at the monitored location.

In one embodiment, a device in a serial network de-multiplexes a stream of traffic in the serial network into a plurality of data streams. A particular one of the data streams is associated with a particular endpoint in the serial network. The device determines that data from the particular data stream associated with the particular endpoint should be reported to an entity external to the serial network based on an event indicated by the data from the particular data stream. The device quantizes the data from the particular data stream. The device applies compression to the quantized data to form a compressed representation of the particular data stream. The applied compression is selected based on a data type associated with the data. The device sends a compressed representation of the particular data stream to the external entity as Internet Protocol (IP) traffic.

A system for communication in an industrial environment. The system includes a server arrangement coupled, via a data communication network to network core, and devices. The system generates timing information for each of the devices using the server arrangement, the timing information is converted into timing packets to be received by each of the devices. The system broadcasts second encapsulated timing packets to each of the devices, via the network core. Communication channel of the data communication network performs first encapsulation of the timing packets and the network core performs second encapsulation of the first encapsulated timing packets. The system receives uplink data for communication from each of the plurality of devices based on the timing information and provide downlink data to the plurality of devices, corresponding thereto.

A building management system network interface device is provided. The network interface device includes a processing circuit with a device interface module and a network interface module. The device interface module is communicably coupled to a refrigeration equipment controller and includes an equipment object configured to receive data values and to populate attributes of the equipment object with the data values. The network interface module is communicably coupled to the device interface module and an external network, and is configured to map the attributes of the equipment object to individual data objects and to write the attributes of the equipment object to the mapped individual data objects. The processing circuit is also configured to execute control logic to control the operation of the refrigeration equipment controller based on the data values received from the refrigeration equipment controller and commands received from the external network.

A configured mode of operation of a wireless sensor network can be established through a dynamic remote configuration process. The plug-and-play universal sensor interface enables the monitoring capabilities of the wireless sensor network to scale seamlessly with the dynamic nature of changing sensor application objectives. A system status module enables a user to view the sensor service to confirm the current configuration of the wireless sensor network.

Apparatus and associated methods relate to a networked system having a master and multiple slaves, where each slave stores a unique (actual) slave address and a non-unique (virtual) slave address in memory, such that each slave is configured to respond to request messages addressed to the slave's non-unique slave address if a sensor device associated with the is in an active state when the slave receives the request message. In an illustrative example, the networked system may be a Fieldbus-style network (e.g., a network implementing the Modbus protocol). A sensor device may be a break-beam, capacitive touch, or push-button device, for example. An output indicator/actuator may be associated with a sensor device to indicate the status of the sensor device to a user. A networked system implementing sensor-activated response gating may beneficially expand the number of slave devices on the network while achieving low latency response times.

A method for detecting physical intrusion attack in an industrial control system based on analysis of signals on serial communication bus is provided. This method comprises of actively sending a detection signal to communication bus via a bus controller in a serial communication bus network, sampling and analyzing signals on the communication bus by a monitoring device, performing differential comparison with a standard signal stored in the monitoring device database, detecting an intrusion signal in difference signal based on noise reduction technology and weak signal detection technology, and according to a detection result of the intrusion signal caused by an external device to effectively determine whether there is an external malicious device in the system, and whether the system is subjected to a physical intrusion attack.

Embodiments of the present disclosure relate to a data transmission method and associated devices. In the method, data collected by at least one monitoring device in a substation is received at a gateway. Further, a status of a connection between the gateway and a first network is detected, where the first network enables communication between the gateway and a server. Further, in response to detecting a disconnection between the gateway and the first network, the data is sent to a user device via a second network hosted by the gateway to enable the user device to forward the data to the server.

A slave device includes a first connector, a second connector, a switch, and a communication circuit. The switch is alternatively connectable to the first connector or the second connector according to a connection way via which the slave device is connected to a master device and another slave device. The communication circuit is connected to the first connector and the switch. The communication circuit is configured to transmit and receive a first communication signal to and from the first connector, and is configured to transmit and receive a second communication signal to and from the switch.
