nGENERALVDS is a software package that runs under a Windows operating system and implements a Web-based human machine interface, OPC server functions, data acquisition from a variety of controllers and devices, and historical data management. Other features include:•VDSViewerisrequiredastheplatformtorunoperationandmonitorwindowsimplementedasJavaapplication,offeringplatform-andscale-independentHMIclients.
