  • Patent number: 11102091
    Abstract: At least one aspect disclosed herein is directed to a SCADA project analysis system. The system includes memory ad at least one processor coupled to memory. The processor is configured to receive information regarding a supervisory control and data acquisition (SCADA) system configured to monitor an industrial process, the information describing at least one first programmable device within the SCADA system, identify at least one analyzer from a plurality of analyzers based on the information, the at least one analyzer being configured to generate an assessment of the SCADA system based on the information, the assessment describing at least one capability of the SCADA system, execute the at least one analyzer to generate the assessment of the SCADA system based on the information, and provide the assessment to an external entity.

  • Patent number: 9672724
    Abstract: According to another embodiment, a system for generating alarm aggregation rules is provided. The system includes a memory and at least one processor coupled to the memory. The at least one processor is configured to receive information descriptive of a set of devices, each device within the set having one or more devices within the set that are associated with the device and each device of the set being capable of entering at least one anomalous state; identify at least one type of alarm aggregation rule that applies to at least one device within the set based on one or more anomalous states that the at least one device is capable of entering; and store an association between an alarm aggregation rule of the at least one type and the set of devices.

  • Patent number: 8190697
    Abstract: Automatically configurable master and slave devices in a master/slave multi-drop serial network are disclosed. In one embodiment, the devices and network utilize the Modbus serial communications protocol over a serial multi-drop network, such as an RS-232 or RS-485 (also referred to as EIA-485) based network. Alternatively, the disclosed embodiments may be used with any master/slave serial multi-drop network. In one embodiment, the master and slave devices include pseudo-slave and pseudo-master auto-configuration operating modes, respectively, whereby slave devices which are introduced to the network may send unsolicited identifying messages to the master device which will determine and assign a unique network address thereto, causing the slave device to configure itself to be responsive to messages addressed therewith and then enter its normal slave operating mode to await such messages. The master device, thereafter, maintains a database of the slave devices and their associated network addresses.
