AN INDUSTRIAL PROCESS CONTROL AND AUTOMATION SYSTEM HAVING DECOUPLED CONTROLLERS
An apparatus is disclosed that is used in an industrial process control and automation system that operates using an open platform data communication protocol. The apparatus includes a processor and a memory, and a communications interface connected to at least one process instrument and arranged to transmit instructions to and receive data from the at least one process instrument and to a data network of the industrial process control and automation system that communicates using the open platform data communication protocol. The apparatus memory contains a system repository file containing process data information sent to the apparatus from the at least one process instrument, a stored function block definition file containing function blocks that define a control strategy for controlling the at least one process instrument and an engineering repository containing the characteristics and parameters for the function blocks associated with the at least one process instrument. The processor operates to communicate the process data from the system repository file to the industrial process control and automation system using the open platform data communication protocol and to receive instructions from the industrial process control and automation system to execute the control strategy.
Method and apparatus for communication in a motor drive application
The subject matter disclosed herein describes a switch embedded in a motor controller and a network protocol executing on the switch to provide communication between devices connected to the motor controller in a motor drive application. The embedded switch is configured to communicate via separate ports with an external controller, a network interface for the motor controller, additional motor controllers, and with the motor or other devices mounted on the motor. The network protocol includes a first tier for data that requires deterministic delivery at a high data rate, a second tier for data that requires a high delivery rate but is also tolerant of some variation in delivery time, and a third tier for data that may be delivered at a slower data rate. The embedded switch receives data at any port, identifies the communication tier to which the data belongs, and delivers it to another port accordingly.
METHOD FOR CONTROLLING ROBOT, STORAGE MEDIUM AND ELECTRONIC DEVICE
Embodiments of the present application provide a method based on an optical fiber communication network for controlling a robot, a storage medium and an electronic device. The method includes: converting an acquired electrical control signal of the robot to an optical control signal; broadcasting the optical control signal over a downlink of the optical fiber communication network; filtering the optical control signal based on a port identifier to obtain an optical control signal corresponding to the port identifier; converting the optical control signal corresponding to the port identifier to an electrical control signal; and sending the electrical control signal to an actuator of the robot. According to the embodiments of the present application, the number of wirings inside the robot is reduced, the wiring complexity is reduced, and the bandwidth for communication and anti-electromagnetic interference capabilities in the control system are improved.
Architecture-Independent Process Control
Process control systems for operating process plants are disclosed herein. The process control systems include control modules that are decoupled from the I/O architecture of the process plants using signal objects or generic shadow blocks. This decoupling is effected by using the signal objects or generic shadow blocks to manage at least part of the communication between the control modules and the field devices. Signal objects may convert between protocols used by control modules and field devices, thus decoupling the control modules from the I/O architecture. Generic shadow blocks may be automatically configured to mimic the operation of field devices within a controller executing the control modules, thus partially decoupling the control modules from the I/O architecture by using the shadow blocks to manage communication between the control modules and the field devices.
Abstraction layers for automation applications
A system for implementing automation functions through abstraction layers includes a control application and an automation equipment abstraction framework executable in a runtime environment. The control application is designed to communicate with automation equipment using one or more automation functions. Each automation function comprises one or more equipment-agnostic instructions. During execution of the control application, the automation equipment abstraction framework receives an equipment-agnostic instructions and an indication of a particular unit of automation equipment. The automation equipment abstraction framework translates the equipment-agnostic instructions into equipment-specific automation instructions executable on the particular unit of automation equipment. These equipment-specific automation instructions may then be sent to the particular unit of automation equipment.
SYSTEM AND METHOD FOR CONNECTED METERING
A universal metering cabinet (UMC) apparatus comprises an input/output (I/O) interface configured to receive at least two data streams, each of the at least two data streams received from one of at least two sensors, and each of the at least two data streams having a different connectivity protocol. The UMC further comprises a customizable programmable interface coupled with the I/O interface and configured to convert the connectivity protocol of each of the at least two data streams into a same uniform connectivity protocol. A method comprises receiving, from the UMC, at least one data stream that includes data from at least two sensors, and receiving, from at least one server, data related to an environment around the at least two sensors. The method further comprises performing data cleansing on the data stream and the data to generate validated data and performing prognostic modeling on the validated data.

REMOTE CONTROL OF FLUID-HANDLING DEVICES
Provided is a process, including: receiving, via the network interface, from a remote user device, a command to change a state of the fluid-handling device to a target state; translating the received command into a translated command operative to cause a local controller of the fluid-handling device to drive the fluid-handling equipment to the target state, the local controller being responsive to the command and feedback from the fluid-handling device indicative of whether the fluid-handling device is in the target state; and sending the translated command to the local controller
WIRELESS PROTOCOL CONVERTER FOR FIELD DEVICES
Techniques for accessing and controlling field devices to collect data and convert protocols include receiving data encoded in a process control protocol, extracting a payload, storing some of the payload, and transmitting some of the payload in a general-purpose computing communication protocol via a wireless network. A method of accessing a field device includes receiving a command of a user from a user communicator, identifying a target field device, generating a command, encoding a protocol-encoded data set, and transmitting the protocol-encoded data set to the target field device. A field communicator device includes instructions for retrieving and interpreting field device data, storing the data, and transmitting the data. A computing system includes a field communicator, wireless user communicator, and a wireless computer network for accessing and controlling field devices in a process plant.
