7.1 Setting an IP address
7.1.1 Assigning an IP Address Using DHCP
ü
Snap the product onto a lower-level device.
ü
Connect the product to a computer via a network cable and integrate it into a network.
ü
Supply the lower-level device with power.
ü
If there is a DHCP server in the network:
•
Assign the network settings to the product.
ü
When the product is delivered, dynamic IP address assignment via the “Dynamic
Host Configuration Protocol” (DHCP) is enabled by default.
•
When the DHCP protocol is enabled, make sure a DHCP server is always present.
ü
If the IP address was assigned via DHCP:
•
Determine this address via the settings or the output of the respective DHCP server,
for example via the output of “Open DHCP.”
ð
Configuration type: static IP address
ð
IP address: 192.168.1.17
ð
Gateway address: 192.168.1.1
Note
Two DHCP servers in one network can cause total network failure!
To prevent network failure, never connect a PC on which a DHCP server is installed to a
global network. In larger networks, there is usually already a DHCP server that can cause
collisions and subsequent network failure.
Note
Assign a fixed IP address to the DHCP server and ensure that a common subnet
exists!
Note that the DHCP server must have a fixed IP address and that the product and DHCP
server must be in the same subnet.
Note
IP addresses obtained via DHCP server are only valid temporarily!
Note that an IP address obtained via a DHCP server is only valid for a limited period of
time. If the DHCP server is not available after the service life has elapsed, the fieldbus
node releases the IP address and can then no longer be reached!
