2.1.2 Peer to peer
Characteristics:
-
Each station is a stand-alone, and therefore contains all the software layers (cli-
ent, server, and communication)
-
The stations can be connected to the communication level configurations, e.g.
NK82xx Ethernet ports, which allow multiple routing.

2.1.3 Distributed client/server configurations
Characteristics:
-
Distributed client and server communicate via TCP/IP connection
-
Provides a straightforward solution for small and medium-sized systems
-
Support of up to 15 client connections, including MM8000 installed clients,
MM8000 web clients, and mobile devices.
-
Each station is specialised for a single function (i.e.MM8000/MK8000 client,
MM8000/MK8000 server or FEP (Front-end processor)
-
Software architecture can be distributed on different PCs for load distribution
-
Optional fault-tolerant redundancy solution with dual servers to prevent service
interruption
-
Optional manual server switch solution for project redundancy or multiple pro-
jects
MM8000:
The client provides the user interface. The server handles all the functional-
ity 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.).
MK8000:
The server provides OPC functionality while the FEP (Front-end processor)
provides connectivity to subsystems.
This architecture allows for scalability from small to big installations, and provides the
highest performance solutions for large systems that require both multiple FEPs and
several MM8000/MK8000 client stations.
