In addition to directly entering the IP address, it is also possible to retrieve this via DHCP.
1. Set the required DHCP mode using p8944 (CBE2x DHCP mode):
Parameter assignment
Meaning
p8944 = 2
The DHCP server assigns the IP address based on the MAC address.
p8944 = 3
The DHCP server assigns the IP address based on the station name.
2. Save the settings with p8945 = 2.
The next time the drive runs up, it retrieves the IP address from the DHCP server.
After the system has run up, you can address the drive as Ethernet participant.
Note
Immediate switchover without restart
The switchover to DHCP is performed immediately
and without a restart if the change is
carried out with the EtherNet/IP command "Set Attribute Single" (TCP/IP Int
erface Object
/ Class code F5 hex, attribute
3), e.g. using an EtherNet/IP control or a commissioning
tool.
Note
When DHCP is activated (p8944 not equal to 0), PROFINET communication via the CBE20
is not possible.
As a consequence, DHCP must be deact
ivated before switching over the interface to
PROFINET.
