Allocate IP Addresses for Network Communications
The AADvance system uses Internet Protocol (IP) for all communications between the
controller and the AADvance Workbench. This includes downloading the application
to the controller and real-time monitoring of the system in operation.
For many systems, the administrator of the local area network will allocate the address
for the controller. If this is not the case, choose an address from the ranges allocated
to private networks:
10.0.0.0 to 10.255.255.255 (10/8 prefix)
172.16.0.0 to 172.31.255.255 (172.16/12 prefix)
192.168.0.0 to 192.168.255.255 (192.168/16 prefix)
Each controller on a particular local area network must have a unique IP address.
Note: You must ensure that the two Ethernet ports on each T9110 processor
module are on different subnets.
Example
As an example you can use subnet masks to ensure that the two ports on a processor
module are on different subnets:
Ethernet port E1-1 Address: 10.10.1.1
Subnet Mask: 255.255.255.0
Ethernet port E1-2 Address: 10.10.2.1
Subnet Mask: 255.255.255.0
The subnet mask defines the first three digits of the IP address, in this case 10.10.1 and
10.10.2.
