can be used, for example, for correction of cross-reference or for pressure compensation
of the device's own measured values.
IP address
Note
Supported IP addresses
The device supports only Class A, Class B, and Class C addresses. You cannot use Class D
or Class E addresses.
IP addresses are used for unique identification of devices within a network or a network
segment. They are used for data exchange between the communication partners via TCP/IP.
An IP address has the following decimal notation:
Table 6- 62
Network mask
Subnet mask
The network mask masks the IP address of a device. The IP address is divided into a
"network component" and a "device component".
Table 6- 63
Subnet mask
IP address
Division
The result is a logical separation of a physically uniform network into different network
segments (subnets). Within a segment the network component must be identical and the
device component different.
Default gateway
The masking determines which IP addresses a device looks for in its own segment and
which are forwarded to a default gateway. The default gateway of a network forwards all
network requests that are not part of the same subnet to other subnets.
