Methods and Systems for Subscribing Remote Devices to Process Control Data
A system communicates process data to a remote computing device. The system includes a processor, a communication unit, and a memory storing instructions for modules. The modules include a scanner interfacing with the communication unit to enable communication with a server via a first network. The scanner enables communication by receiving data from the server, identifying polling requests in the data received, and transmitting request lists to the server in response to the polling requests. The modules also include a data stream processor determining a set of process data values in the data received, the set of process data values corresponding to view list data to be communicated to the remote computing device. Another module is an application program interface (API) interfacing with the communication units to enable communication with the remote computing device a second network by transmitting the set of process data values to the remote computing device.
Methods and Apparatus for Configuring Remote Access of Process Control Data
A method of providing process data to a remote computing device includes receiving configuration data describing a configuration of at least part of the process control system. The configuration data includes information associated with a plurality of process control entities, and the information regarding each entity includes at least one tag associated with a level in a hierarchy of the system. The method includes identifying a plurality of levels within the system based upon the tags, including at least a first-level identifier and a plurality of second-level identifiers associated with the first-level identifier. Further, the method includes identifying a plurality of control modules, each associated with a second-level identifier, and each associated with the entities based upon the configuration data. The method includes generating a hierarchical list of available process data, and selecting from the hierarchical list a set of information to include on a watch list or alarm list.
Mobile Devices for Remote Access of Process Control Data
A tangible, non-transitory computer readable medium stores machine readable instructions optimized for a microprocessor on a mobile computing device. When executed by the microprocessor, the instructions cause the microprocessor to display a graphical user interface (GUI). The instructions also cause the microprocessor to receive, via the GUI, a selection of one or more items to view. Each of the one or more items is related to a process control system. The instructions cause the microprocessor to transmit to a mobile server, via either the Internet or a mobile telephony data connection, the selection of the one or more items. Thereafter, the instructions cause the microprocessor to receive from the mobile server, via either the Internet or the mobile telephony data connection, a plurality of real-time values corresponding to the selected one or more items, and to display the plurality of real-time values on the GUI.
SYSTEMS AND APPARATUS FOR DISTRIBUTION OF PROCESS CONTROL DATA TO REMOTE DEVICES
A system for securely disseminating information relating to a process control plant includes a process control node and a controller that is coupled to a plurality of process control devices. The process control node includes a communicator module operable to transmit, via a first network, information of the process plant received from the controller. The system also includes a data services module operable to receive from the communicator module, via the first network, the information of the process plant and to transmit some or all of that information via a second network, and a mobile server, coupled to the second network and to a third network, and operable to receive data from the data services module. The mobile server is operable to communicate with a plurality of mobile computing devices via the third network.
SYSTEM FOR CONTROLLING REMOTELY CONTROLLED EQUIPMENT
A system for controlling a remotely controlled equipment. The system includes an operator station with a main operating device which is operated by an operator to provide a main operating device signal, an operator station controller, and a confirmation operating device which is operated by the operator to provide a confirmation operating device signal. An equipment controller is connected to the operator station controller. A first gate is connected to the equipment controller. The first gate enables an operation of the remotely controlled equipment. A critical action controller receives the confirmation operating device signal. A second gate is connected to the critical action controller. The second gate enables the operation of the remotely controlled equipment.
METHOD, NODES AND COMPUTER PROGRAM OF A TOOL COMMUNICATIONS NETWORK
A method performed by a tool communications network for remote control of power tools includes: determining control data and arranging the control data in a message structure by a tool server. The message structure includes a message header for message transmission and a message body, including at least one data container, for carrying control data. The data container contains at least one individual control data item containing metadata and value data, and is expressed in a binary format. The method also includes: transmitting by the tool server a message based on the message structure including the control data; receiving by a tool controller the message based on the message structure comprising the control data; and storing the control data according to the message structure in a database of a plurality of tool controllers. At least one power tool is connected to at least one tool controller.
