So for example if I start up this chart, we can watch this chart run here in the Designer. When a Sequential Function Chart is started, we can also monitor it visually here in the Designer. So here in the Designer is where we do our design work and our programming for the Sequential Function Charts. But SFCs in general are a way to program using elements in a grid, and the logic flows through the elements as they're connected. And of course in later lessons we'll go over all of these individual elements. And you see you can sort of get a quick overview of what these charts are going to end up looking like. So for example, here is an example chart that we have that mimics a basic batch process. So here in the Designer we have our Sequential Function Charts node, and we can create new charts from here, or if we have existing charts, we can access them here. Even if they're started by the action of a client for example, the chart always executes on the gateway. However even though you're creating them in the Designer, Sequential Function Charts always execute on the Ignition gateway. So the Designer is where you're going to create, delete, and design all of your Sequential Function Charts. And just like other resources inside of Ignition, they're managed from inside the Designer. So all of the projects that you have installed can access and start up all the same set of Sequential Function Charts. It's important to understand that Sequential Function Charts don't belong to any specific project that you have installed on your Ignition gateway, rather they're gateway-wide.

When you install the SFC module and launch the Designer, you'll have a new node in the Project Browser of your Designer here under the Global section called Sequential Function Charts. Sequential Function Charts, often called SFCs, are a powerful way to perform visual programming using Ignition.
