7.2.1. Definition of IP Addresses
An IP Address is a required setting in order to allow data communication in an Ethernet net-
work. If the devices are integrated in a plant network, the local network administrator has to
be consulted to find correct settings.
The Subnet Mask defines the size of the network. In typical applications the subnet mask is
as per default settings. However, the local network administrator has to be consulted, if
other IP addresses than the default settings apply.
The Broadcast Address is required for the MNS Digital Gateway to send data to other devices.
Since the MNS Digital Gateway does not know which IP address is used by the other devices,
data is sent as broadcast messages. The broadcast address is calculated automatically by
MNavigate.
The Default Gateway is an address for a network gateway, if the switchgear control network
is connected to a plant network. The gateway is not part of the MNS scope. If a gateway is
used, the local network administrator is to be consulted for correct settings.
If it is not possible to communicate to the MNS Digital Gateway, please refer to the
trouble shooting section in this document or the MNS Digital Gateway section in the
MNavigate Help file
7.3. Settings – Serial Switchgear Bus
The serial switchgear bus setting defines the Modbus RTU setting of MNS Digital Gateway as
a Modbus master to the M10x-M devices. This parameter needs to be set correctly in order to
establish communication between MNS Digital Gateway and M10x-M. The list of parameter is
shown in the following table
