  • Scalability: zspc can be used as a stand alone application or as a company-wide server application.

  • Expandability. The multi-tier technology makes it possible to distribute the functions into different nodes within the network.

  • Thin Client GUI’s: As a zac application, zspc has a Thin Client GUI. It is possible to access the SPC server many-times with a universal, slim Client application with a low data rate. zspc can be integrated in web portals.
