It means that a maximum of 254 different sub networks can be configured in
REF. The REF is only building a switchgear overview for the matching
subnet part. The identification of the subnet part and IP part is REF 542plus
specific, but is not in conflict with any standard.
The subnet mask with the number 255.255.255.x determines
only one subnet and not any other subnetwork can have access
to it. It is allowed to configure sub networks with that mask.
6.4.5.
Default gateway configuration
This parameter specifies the gateway IP address. This is the address to use
when forwarding packets to a network other than the one the switch belongs
to, see Section 6.4.2. TCP/IP configuration for REF 542plus parameters'
configuration.
The default gateway configuration is only required if it is
intended to address the network configurable devices from a
management station separated from them by a router.
The default Gateway IP address has to be inside the subnet
mask.

Example of a subnet configuration
How to create two sub networks: The two networks are identified through the
3rd address identifier.

REF is building in this case two switchgear overviews from the two different
subnet identifiers, because only the matching 3rd identifiers are moved to one
subnet. To see with one computer both the Subnet 1 and Subnet 2, the 3rd
identifier in the subnet mask of the computer must set to 255.255.254.00 or
below which is IP standard.
