Requirements
• The configuration of all parameters of the network settings can be changed
also withtextual command interface (telnet session)
• It should be possible for one or more non−configured component (s) in any
network tofind and configure
• It should be possible to set up a network to scan existing components (all
components)
Implementation
Parametrization
The network settings are stored in the device. Since the communication with a
component on the network, will change the setting during the
parameterization only after a restart effect. Restarting can also be triggered
with an command.
Network scan and manual configuration
The only way to fit a non−configured network device in an IP network address,
is the possibility of UDP broadcast messages to a specific port number.
The UDP layer detects valid (eg see table) telegrams using the telegram
header (START: 0x12345679 The data area contains the network parameters.
