Design Pad G4 can be used to configure a single control station or a distributed network of multiple controllers. Design Pad G4 uses workspaces to organize the collection of hardware configurations and control schemas that form a multi-station control strategy. Workspaces can be used to organize any collection of documents---even documents that are loosely related or not related at all.
In addition to organizing documents, workspaces provide a means to configure communication networks, to configure OPC server gateways, and to communicate with devices on a controller network. (An OPC server is a standalone software item that serves as a gateway between a controller network and a PC network. It is often used to link controllers to Human Machine Interface (HMI) software executing on a PC.)
Fairmount Automation advises implementing a version control system (like Subversion) to keep track of file changes if they do not already have one in place.
