DeviceNet Created Sep 11, 2018 (21:30)

Database also known as Relational Database Management System (RDMS) which is the full technical name for pretty much every database on the market today. Not many other kinds of databases are popular. A relational database is a piece of software that stores data in related tables. These tables have data stored in columns, each column has a specific datatype. Tables themselves are flat (2-dimensional), but can be joined together to access data in a variety of ways. Some example of RDMSs are: MySQL, PostgreSQL, Oracle, Microsoft SQL Server, and IBM DB2.

Diagnostic Tags Created Sep 11, 2018 (21:30)

Not being restricted to any one database, but supporting all types. We're not stuck with the opinion that only one database is "correct" but we created our programs to be useable with any type of database - including all rather than omitting any.

discrete manufacturing Created Nov 17, 2018 (00:17)

Software which encapsulates databases and handles communication requests. Examples: MYSQL Server, MySQL, Oracle, DB2, PostgreSQL and others.

A dataset (or data set) is a collection of data, usually presented in tabular form. Each column represents a particular variable. Each row corresponds to a given member of the dataset in question. It lists values for each of the variables, such as height and weight of an object. Each value is known as a cell. The dataset may comprise data for one or more members, corresponding to the number of rows. -Wikipedia

Distributed Component Object Model (DCOM) is a set of Microsoft concepts and program interfaces in which client program can request services from server program on other computers in a network. DCOM is based on the Component Object Model (COM), which provides a set of interfaces allowing clients and servers to communicate within the same computer. Now this is sometimes referred to as OPC-DA

dynamic reports Created Oct 31, 2018 (16:28)

Distributed Control System is a big PLC that is typically networked to other controllers, PLCs or field devices. It typically has a workstation to interface with the controller and can be very expensive due to built-in security and failover features.

Dead-Band is the range a value can change in and not count as a change. This is important for analog values because a liquid stored in a tank may change levels by a tiny bit constantly as trucks drive by. Deadbands (used correctly) reduce the amount of data stored without sacrificing real information.

driver Created Sep 11, 2018 (21:30)

An open network which is used to eliminate lots of field wiring by communicating directly between controllers and field devices such as photoeyes, temperature sensors, valves, motor controllers, and so on.

Distributed Component Object Model Created Oct 3, 2018 (17:41)

Refers to manufacturing of individual items such as cars as opposed to Process Manufacturing which refers to continuous streams of production such as oil from a refinery. Discrete manufacturing generally uses PLCs for control, and Process Manufacturing generally uses Process Control systems. There is some crossover, but each type system (PLC or Process Control) is best suited to its own industry.

Big names is PLC control are:  Allen-Bradley, GE, Siemens, Modicon, Automation Direct, and Omron. Big names in process control are:  Honeywell, Porter & Fisher, Rosemount, and Bristol Babcock.

Distributed Network Protocol Created Oct 3, 2018 (17:41)

In Ignition, it means that the operator can change the content of the report from a runtime Client. Reports are generated based on the binding information on the report's root container. The binding can be either static (no changing) or dynamic (influenced from another location or component through binding).

dword Created Nov 17, 2018 (00:15)

The ability to click on an object and drag it onto the screen. This is most commonly referring to creating projects in the designer by dragging components onto a window. This is often how WYSIWYG editors work.

dashboard Created Mar 22, 2017 (23:42)

  • dashboards

A dashboard is a display that was created to view a large amount of data without any control. This is usually an aggregate of many pieces of data from many locations. Often a separate dashboard will be created for managers, while the operators will use specific control screens.

Designer Created Mar 24, 2017 (23:24)

The Ignition Designer is the piece that allows you to make changes to your projects. Launch it from the Gateway and inside it you can create windows for you clients, Tags, Transaction Groups, and much more. It is a special Java runtime that runs similar to a client but has all the tools you need to create.

data-centric Created Apr 27, 2017 (22:13)

A task or system that is focused around interacting with data. This could mean reading, writing, or both. Often it is referring to data stored in a database.

deployment Created Apr 27, 2017 (23:43)

When we talk about deployment in Ignition, we often say things like "instant deployment" or "deploy changes to you users." In this case we are referring to making changes to your projects and sending those updates out to existing clients. We say that Ignition has instant deployment because all published data is immediately sent to all open clients.

driver Created May 30, 2017 (18:53)

In Ignition a Driver usually refers to a module that allows you to interact directly with that specific type of device (Modbus, Allen-Bradley, etc.). The OPC-UA module is required to use these drivers.
