3.5.5 Address setting via the mode DHCP
switch position: 400
Address setting is carried out by a BootP-server in the network after the start-up of the gateway.
DHCP supports three mechanisms for IP address allocation:
In "automatic allocation", the DHCP-server assigns a permanent IP address to a client.
In "dynamic allocation", DHCP assigns an IP address to a client for a limited period of time. After this
time, or until the client explicitly relinquishes the address, the address can be re-assigned.
In "manual allocation", a client's IP address is assigned by the network administrator, and DHCP is
used simply to convey the assigned address to the client.
PROFINET
Please assure, that in PROFINET -applications, the address assigned via a BootP-server corresponds to
the address, which is assigned in the configuration tool.
3.5.6 Address setting via mode PGM
switch position: 500
The PGM-mode enables access of the software I/O-ASSISTANT to the module’s network settings.
Note
The IP address, as well as the default subnet mask assigned to the station by the DHCP-server,
are stored in the station’s EEPROM.
If the station is subsequently switched to rotary- or PGM-mode, the settings carried out via
BootP (IP address, subnet mask, etc) will be read from the module’s EEPROM.
Note
In the PGM-mode, all network settings (IP address, subnet mask, etc.) are send to the module’s
internal EEPROM and stored permanently.
