Introduction
The Playback widget allows you to move through the time of a PIVision display using a time step defined in the widget configuration.
The PI Vision of AVEVA is available from 2017 and allows viewing real-time data from PI Data Archive and data organized in assets from the AVEVA Asset Framework (PI-AF). In order to achieve PI Vision displays, Simply access to https://webServer/PIVision (indicating the correct name of the webserver machine).
The most recent versions of most HTML5 compatible browsers are supported on computers, tablets and phones running Android and iOS.
In PI Vision the configuration of the elements is quite intuitive and is characterized by a simple drag-and-drop of the control into the display.
