摘要:
An industrial control system may receive data associated with at least one component within an industrial automation system. The industrial control system may then determine whether the data is associated with at least one of a plurality of data tags, such that the at least one of the plurality of data tags describes at least one characteristic of the data. The industrial control system may then broadcast the data and the at least one of the plurality of data tags in a data feed channel when the data is associated with the at least one of the plurality of data tags.
摘要:
A method for serial data transmission between a position measuring system and a processing unit that includes transmitting position data and further data between the position measuring system and the processing unit in serial form as digital data words, transmitting up-to-date position data between the position measuring system and the processing unit upon a position request command and always transmitting further data, whose processing is not time-critical, immediately following the up-to-date position data.

The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. More specifically, the invention relates to systems having two or more controllers for controlling devices, wherein information related to the system can be shared between controllers, e.g. by updating a second controller with the newly learned information of a first controller, or by replicating a controller by making a second controller a complete copy of a first controller. The information can be shared by, in a first controller, generating and transmitting signals comprising device identifiers of devices controlled by the first controller, receiving said signals at a second controller, and storing said device identifiers in an organized data structure in a memory of the second controller. This function proves advantageous when new controllers are introduced in the system or if a controller is lost, worn out, or destroyed.

The present invention relates to a wireless home automation system having a controller for controlling a broad variety of functions via two ways communication with a plurality of devices. More specifically, the invention relates to a new and flexible way of establishing a wireless network by using devices which functions as both input/output devices and repeaters. By establishing an even distribution of dual-functionality devices, the user can reach any device without use of dedicated repeater stations. The controllers and devices of the system comprises means for generating a signal comprising a destination identifier, instructions related to the input/output of the destination or source device, and a repeater identifier. The devices according to the invention are adapted to act as input/output devices and signal repeating devices in that the processors of each device comprises means for, upon reception of a signal, processing said information in its processor if the destination identifier corresponds to the device identifier of the device, and means for, upon reception of a signal, transmitting a second signal holding at least said destination identifier and said instruction if the repeater identifier corresponds to the device identifier of the device.

The process uses the technique of carrier currents between the emitter-receivers (2, 3 . .) called slaves comprising each a microcontroller (4, 5 . .), and a master controller (6) comprising a microcontroller (7) whose memory contains addresses relating to the slaves and to the dwelling. According to the invention, during connection of a slave to the network there is activated the master controller (6) by typing a number on the programming keyboard of the master controller (6), one pushes a pushbutton (13) so as to trigger a subprogram (14) for production of a message (M1) containing the following information: general distribution; request for address allocation; slave address, there is sent (15) the message. One awaits (16) a second message (M2) from the master controller, then during reception of the second message M2, the applicant slave sends to the master controller (6) an acknowledgement AS comprising information on the allocation of the slave, this information being transmitted to the user by means of a display.
摘要:
A communication apparatus is provided, which may include a node having a processor and a computer-readable medium, the node being associated with an electrical component of a real-time embedded control system configured to control one or more electronic components. The communication apparatus may further include a program stored on the computer readable medium that, when executed by the processor, is operable to identify data to be communicated, and divide the data into one or more frames. Each frame may include a frame header and a frame data payload portion. The frame data payload portion may include one or more segments, forming a sequence of segments, each segment including a segment header including segment data indicating a location of the segment in the sequence. The segment may also include a segment data payload portion.

The present invention relates to a wireless home automation system having controllers for controlling a broad variety of functions via two-way communication with a plurality of devices. More specifically, the invention relates to sharing information related to the system between controllers, e.g. by updating a second controller with the newly learned information of a first controller, or by replicating a controller by making a second controller a complete copy of a first controller. The information can be shared by generating and transmitting, with a first controller, a list of device identifiers of devices controlled by the first controller to a second controller. The list is received by the second controller and stored in a memory of the second controller dedicated to store device identifiers of devices controlled by the second controller. This function proves advantageous when new controllers are introduced or if a controller is lost, worn out, or destroyed.
摘要:
A safety system programmable logic controller provides for cross connection of inputs and outputs of separate independent control modules through the use of virtual wire connections passing as messages on a single logical backplane. The backplane executes a high level protocol that provides wire-like indications of communication failures mimicking those of separate physical wires.

A stage lighting system is comprised of a plurality of lamp units which may have diverse communication protocols, functions and data parameters. The stage lighting system is controlled by a modular control system comprised of a modular controller mainframe interconnected with a plurality of control devices which may have diverse communications protocols and data formats. The modular controller mainframe consists of a plurality of input and output modules, mass storage devices and a main processor kernel, all interconnected by a number of data buses. The input modules serve as an interface between the modular controller mainframe and the diverse protocols of the various control devices. Similarly, the output modules serve as an interface between the modular controller mainframe and the diverse protocols of the various types of lamp units. The modular controller mainframe serves as an interface system by providing one or more of said input or output modules with the capability of translating parameter commands, where necessary, to accommodate control devices having diverse communications protocols and output devices having diverse communications protocols, functions and data formats. The system may also include a distributed control system for a lighting system in which two or more fully-functional control devices are online simultaneously to control any function of any of a plurality of luminaries from the control devices. Various methods for arbitrating and resolving conflicts between or among plural control consoles are also used.
