Abstract: In a Graphical Programming System, Users may develop algorithmic programs for Controllers or Controller Assemblies utilizes Programming Tools located on a Central Server. Users access the Central Server utilizing a Client connected by the Internet, an Intranet, or a Local Area Network (“LAN”). A programming Project resides on the Central Server but is displayed on the Client, allowing the User to modify the project from the Client. Actions are transmitted as XML, or similar, files which are processed by the Programming Tools. Multiple Users may access the Project simultaneously and a Project may be temporarily interrupted, only to be re-initiated from any Client connected to the Central Server. Additionally, the Graphical Programming System may be utilized to simulate real-world processes. Once a Project is completed, respective machine code may be transmitted to Controllers or Controller Assemblies connected to the Central Server.
