I’m not sure I understand your question. Edge includes the Ignition OPC server and some drivers for popular products. Edge includes support for 2 weeks of private (internal) history storage using Ignition’s standard tag history system. That tag history can be forwarded to a central gateway for longer storage.
Edge will only be able to collect data from a supported device. If your device isn’t supported out of the box, Edge won’t work for you. Unless you have hundreds of potential installs, which might justify whitelisting your custom module for use with Edge. Your sales agent can talk about the options, for which I am not up to speed.
I don’t use or recommend Edge, myself, as I always install at least my Simulation Aids module in any projects I deploy.
