Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
The change in offset error due to change in temperature. As temperature varies from +25oC, the possible offset error increases. The offset error drift is specified in LSB/oC of full scale.
Industry:Automation
A collection of routines and data structures that performs a particular task or implements a particular abstract data type.
Industry:Automation
A symbolic name used in a tag to identify a specific entity within a complete set of related entities. For example, an I/O definition file may contain a tag (definition) for each I/O — with each I/O definition containing a unique tag name by which the I/O can be addressed.
Industry:Automation
The combination of messages normally occurring on a communication network; the first message is a command for work to be done, the second message is a reply (from the station receiving the command message) gives information on the status of the work. If the work is completed successfully, the reply message contains any data requested; if completed unsuccessfully, it indicates the reason for the failure.
Industry:Automation
A communication model in which data is identified by its content rather than by its source or destination. Devices that need the data (consumers) recognise the data they need and consume it. Therefore, data only needs to be sent out on the network in a single message no matter how large the number of nodes to which it needs to go.
Industry:Automation
A system containing multiple hardware units located at different physical locations; individual hardware units do stand-alone processing, but can also be interconnected to share data with other locations or with a central facility. This may include terminals, programmable controllers, or intelligent I/O modules.
Industry:Automation
A communication protocol sanctioned by the International Standards organisation (ISO) that defines procedures for the data link and physical protocol layers.
Industry:Automation
A system in which two or more devices actively control the outputs of a system. Each device in the system votes on every control decision.
Industry:Automation
The commutator is a cylindrically shaped assembly that is fastened to the motor shaft and is considered part of the armature assembly. It consists of segments of “bars” that are electrically connected to two ends of one (or more) armature coils. Current is from the power supply through the brushes, to the commutator and hence through the armature coils. The arrangement of commutator segments is such that the magnetic polarity of each coil changes as the armature rotates.
Industry:Automation
A company that acquires hardware and software in complete form and resells it to the public, adding value such as user support and service.
