MNS Digital Gateway connected to Switchgear Control Network providing facility to connect
additional MNS Digital Gateway and other system tools and components (e.g. MNS Digital
Edge Gateway, Web browser, Time Server, configuration tool, etc.). A network switch has to
be installed in the plant. All network components are connected to the switch with standard
CAT5 / CAT6 patch cable.

It is recommended that a managed network switch is used to connect the MNS Digital
Gateway to the PCS or PLC. The switch is not part of the MNS assembly but may be
delivered together with the switchboard depending on project scope definition.
To ensure proper system performance following design rules shall be obeyed:
· Not more than 2 MView (optional) shall be connect to one MNS Digital Gateway
· If many MNS Digital Gateway are connected to the same network then network

performance slows down. In such a case the network shall be split into different
LAN segments (e.g. VLANs – can be configured in managed switches).
