Characteristics:
–
Software architecture distributed on different hardware;
–
Each station is specialised for a single function;
–
Optional redundancy solution with dual servers to prevent service interruption.
MM8000: The client provides the user interface. The server handles all the func-
tionality provided by MM8000, and holds the configuration database. The FEP
(Front-end processor) provides the drivers for the different network connections
(such as Cerloop, NK8000, etc.);
New! MM8000 now provides OPC client functionality for OPC Data Access
Server subsystems.
MK8000: The server provides OPC functionality while the FEP (Front-end proc-
essor) provides "background" functionality.
This architecture provides the highest performance solutions for large systems
that require both multiple FEPs and coordinated management.
