A-34 Fieldbuses
AC30 series Variable Speed Inverter
IP Address Assignment
Local and DCP IP address assignment is supported.
Local assignment refers to setting the IP address via the GKP, using the tools PDQ or PDD, or from within the inverter’s application. For the
AC30, local assignment also can refer to the use of DHCP or Auto-IP.
DCP assignment refers to setting the IP address via a PROFINET configuration tool or from the PLC itself when a connection is made. This is
either marked as permanent or temporary.
The current IP settings of the inverter are monitored using the parameters:
0926 IP Address
0927 Subnet Mask
0928 Gateway Address
Local Assignment
If parameter 0929 DHCP is set to TRUE, then the IP address will be set from the DHCP server on the network, if one is available.
If parameter 0930 Auto IP is set to TRUE, then the IP address will be automatically be assigned a link-local address.
If both parameters 0929 DHCP and 0930 Auto IP are FALSE, then the IP address, subnet mask and gateway address will be set from the values
in the parameters:
0933 User IP Address
0934 User Subnet Mask
0935 User Gateway Address
DCP Assignment
When the IP address is set via DCP then the parameters 0929 DHCP and 930 Auto IP will both automatically be set to FALSE.
Note: The enabling of DHCP via DCP is not possible.
The IP address is stored in non-volatile memory and marked as temporary or permanent when the IP address is assigned via DCP. If the IP
address is marked as temporary, when the PROFINET device is re-enabled or power-cycled the IP address will be 0.0.0.0 as per the PROFINET
specification. If it is preferred that this does not happen then the parameter 3134 PROFINET Use Drive IP should be set to TRUE. In this case,
on enabling the PROFINET device the last IP address of the inverter will be used.
