Setting IP address parameters via DCP
Initial startup
For PROFINET IO, the IP address parameters are determined via the "DCP" protocol
(
D
iscovery and
C
onfiguration
P
rotocol). DCP operates with device names. The device
name uniquely identifies a PROFINET IO station in the network. It is identified with the
PROFINET IO controller when configuring the station and is set using the project
planning software on the PROFINET IO device. With the aid of the device name, the
controller identifies the device during startup and transfers the corresponding IP address
parameters. Settings directly on the slave are no longer required.
Resetting IP
address
parameters
If you do not know the IP address parameters and cannot access the inverter using the
serial interface or the DBG60B keypad, you can reset the IP address parameters to the
default values using DIP switch "2
0
".
This action resets the DHR21B/41B option to the following default values:
•
IP address: 192.168.10.4
•
Subnet mask: 255.255.255.0
•
Default gateway: 1.0.0.0
•
PROFINET device name: PNETDeviceName_MACID
Proceed as follows to reset the IP address parameters to the default values:
•
Switch off the 24 V DC supply voltage and the line voltage.
•
On the DHR21B/41B option, set DIP switch "2
0
" to "1" (= right = ON).
•
Switch the DC 24 V supply voltage and the line voltage back on.
•
Wait until the DHR21B/41B option has booted up. This is indicated by the green
"Run" LED.
