AC30 EtherNet IP Option 
Configuration 
The option requires configuration of the device address and mapping 
of the process data to the master. The Producer Assembly instance 
number and Consumer Assembly instance number may be changed 
from the defaults if required.  Note that some communication 
parameters only become active after the AC30 leaves the 
configuration state. 
 
The 0044 Comms Required parameter must be set to ETHERNET 
IP.  
 
Address 
There are three methods to set the IP address, subnet mask and 
gateway address of the device: the slave sets its own address, the 
address is set externally, say be a PLC, or the address is set by a 
DHCP server.   The parameter 0199 Address Assignment is used to 
choose the method. 
 
If the IP address is set by the slave (Address Assignment = FIXED) 
then three further parameters must be set.  These are: 
0200 Fixed IP Address 
0201 Fixed Subnet Mask 
0202 Fixed Gateway Address 
 
Producing / Consuming Instance Numbers
The Producing Instance Number may be changed from its default of 
0064h if required using the parameter 0226 ENET Producing Inst 
The Consuming Instance Number may be changed from its default of 
0096h if required using the parameter 0227 ENET Consuming Inst  
The Configuration Instance Number is fixed as 0005h. 
 
Process Data 
The cyclic I/O data is configured by using the read and write process 
data mapping tables in the AC30.  These tables are two parameter 
arrays in which AC30 parameter numbers may be added.  
At least one AC30 parameter must be mapped to the process data. 
String-type parameters may not be mapped. 
 
Read Mapping 
The read process data represents cyclic data sent from the PLC to the 
AC30.  Only writable AC30 parameters, that are not configuration 
parameters, may be added to the read process data.
