Introduction It is important to distinguish between the project development environment and the project runtime. You can use the project development environment to design, develop, troubleshoot, deploy, and monitor projects. In contrast, the project runtime actually runs your project, communicates with external databases and devices, and serves screens to project viewers. The full AVEVA Edge 2020 software for Windows includes both the project development environment and the project runtime. Your software license determines which parts of the software you can use on any given computer or device. For more information, see Execution Modes on page 25.
In contrast, Embedded HMI and Compact HMI are the runtime editions for Windows Embedded Standard and Windows Embedded Compact, respectively. They cannot be used for project development, so they have lower system requirements than the full AVEVA Edge 2020 software. IoT View is a new, platform-agnostic runtime edition for other embedded devices. It has very low system requirements and somewhat limited features.
In most cases, the first thing you should do is install the full AVEVA Edge 2020 software on your primary workstation, because it not only sets up the project development environment for you, it also unpacks the rest of the components so that they can be installed on other computers and devices. Note: We recommend that you use Mobile Access instead of our traditional Thin Client software whenever possible. Thin Client depends on legacy, Windows-only technologies, while Mobile Access allows you to use any HTML5-compatible browser running on any platform as a project viewer.
Mobile Access does not yet support all of the features that Thin Client does, but we are continuing to improve Mobile Access with every new release. Differences between the runtime editions You can develop projects once in the Studio development environment and then run them on any of the runtime editions. This section describes the differences between the editions, so that you can decide which to use. The following table shows the minimum system requirements for each runtime edition.
