(open in window)[00:00] In this lesson, I'll provide an overview of Ignition Edge. Edge is a lightweight, lean version of Ignition designed for edge of network solutions. Edge can come pre-installed on a range of edge of network devices that are ready out of the box, but it can also be installed on a wide variety of operating systems such as Windows, Linux, and Mac OS, and with its ARM processor support, it can run on devices like Raspberry Pi. We have specific zip installers on our downloads page, or Edge can also be installed via the normal Ignition installer. To do this via the standard installer, I just need to access the gateway webpage after installation, and when I get to the first step of the commissioning process, I'll choose Edge from the different additions. From here, I'll accept the Inductive Automation eula, set up my administrator user and start the gateway.
[01:03] We'll wait for the gateway to start, and once it does I'll log in. You may notice that the branding is different from a standard Ignition installation, but navigating the gateway webpage will feel familiar. There is an Ignition Edge page available in the platform tab, and for the most part, this is where we can configure and learn about Edge specific features. Right away, we have access to the edge settings, but first I want to look at this products and modules tab. Each product here represents a set of features to resolve pain points at the edge of the network. We can see on this page a brief description of their purpose and that ranges from HMI support, edge of network data synchronization, enterprise administration architecture, amongst other things. So after you install Edge and determine which set of products you need, then you can activate an Edge specific license with the necessary modules just like you would on any standard license.
[02:04] As previously mentioned, edge is a lightweight version of Ignition and that comes with certain differences and limitations. I'm not going to go over every one of them in this lesson, but I'll provide a link to our user manual page where you can learn more about Edge. I will go over some of them as they are related to the settings in our Edge settings page. Going from the top down, we can change the name of our project. Edge Installations automatically have this Edge project created, and they're also limited to having just one project. Next, you can set the designated tag provider by default. This Edge one is set and you are only allowed to create one tag provider. We can also change the historian's name. Edge comes with its own historian as it cannot directly connect to a database for tag history storage. Remote history providers can be configured, but we'll go over that more in the sync services lesson. Finally, we are able to change the visualization module. If you have the Edge panel product for HMI support, you are limited to having only one visualization module set at a time by default.
[03:07] This is set as vision and you can change it over to perspective. Of course, whatever you do set here means that the other visualization module will fault preventing the designer from accessing resources to the faulted module. That wraps up some of the main distinctions between a standard installation of Ignition and Ignition Edge. Edge offers a lot of the same functionality as a standard install, but in a scaled down lower cost version that makes it perfect for edge of the network architectures.
