Port address for local and for external stations
The port address determines the address of the connection that is used for the transfer of
data. The port address for the local station may be compared to the local (own) TSAP on the
H1-level. A port address consists of a decimal number (16-bit-address) of 5-digits. Both,
TCP as well as UDP use port addresses for data transfers to the respective application level.
Please note that port addresses 1024, 7777 and the range from 0 to 255 have been reserved
for common services. The port address for the local station and the external station must be
different.
Range: 0 to 65536
IP-address
The IP-address is a 32-bit-address that must be unique within the network. The address
consists of 4 numbers that are separated by a full stop.
Range:000.000.000.000 to 255.255.255.255
You can obtain the IP-address from your system administrator.
You may enter an unspecified port address or IP address, i.e. the port or IP address are irrelevant
when evaluating messages if the post address is o or the IP address is 0.0.0.0.
