![]() ![]() The state of the transition can update in realtime, so a chart can pause until a user approves the chart to move on. Flow of the chart can be halted by a transition element. Doing so allows for looping logic to be built directly into the chart. They start at their begin step, and the logic of the chart typically flows from the top to the bottom, however charts are able to loop back to previous steps. Each element does something different, but they generally serve to either control the flow of the chart, or execute one or more Python scripts.Ĭharts always flow in the same way. Simple Visual interfaceĬharts elements are drag-and-drop, and work similarly to the components you are used to using in the rest of Ignition.Ĭharts are comprised of elements, and these element perform the work in a SFC. Parameters can also be passed into a chart as it starts, so multiple instances can work on separate tasks individually. ![]() They make use of both Python and Ignition's Expression language, so any number of tasks are possible from a single chart. A single SFC in Ignition can be called multiple times. SFCs are built in the Designer, and executed on the Gateway, so they run independently of any Clients. Scripts in a chart can only be invoked by the chart, so external scripts or resources will not be able to directly call the code from any of the steps.
