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
1) Reliance-development software used to create application programs. 2) In a numerical control system, software that controls execution of the application programs. (See operating system.)
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 reply message that is immediate because the message data is available at the link level.
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) recognize 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
Numerical information that can be changed during application operation. It includes timer and counter accumulated values, thumbwheel settings, and arithmetic results.
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
1) A circuit in which the signal can vary continuously between specified limits. 2) A circuit that provides a continuous function. 3) Contrasted with digital circuit
Industry:Automation
A memory characteristic wherein all data is entered sequentially at a single input or retrieved sequentially from a single output.
