FactoryPMI is a legacy software product by Inductive Automation. It is now encapsulated in the Vision module for Ignition. It is a sophisticated HMI/SCADA package that uses any SQL database as the primary data store. Runtime and Design environments are web-launched, rather than being installed by hand on each workstation. PMI stands for Plant Management Interface. FactoryPMI had a similar Gateway, Designer, and Runtime (client) to what Ignition has now.
FactorySQL is a legacy software product by Inductive Automation. It is now encapsulated in the SQL Bridge module for Ignition. It is a sophisticated communication bridge that synchronizes and/or logs data between PLCs and SQL databases.
To fail over is to automatically switch to another copy of your client or device. This should only happen when something has gone wrong with the primary object. A failover device (or piece of software) is a second copy that will be used when the primary fails.
This refers to a computer that holds files that are available to the network. Often Ignition will save reports onto a file server, or access files from a file server and load them into a database or display them for users.
When a component has focus, you are able to interact with it through the keyboard. Only one component at a time can have focus. Clicking on a component or pressing tab takes focus away from one component and grants it to the next.
Any components that you can interact with can hold focus, for example, input fields like a numeric text field or drop-down menu, tables, and some chart components. Static components like images or tanks cannot hold focus.
FTP (File Transfer Protocol) is a standard way for programs to upload and download files from a computer or service. Generally, this implies you are going through the internet to connect to the computer hosting your files.
