If the module will be communicating on a local network, make sure the default IP
network address is not already in use on that network. To determine the default IP
network address, locate the global address label on the front panel of the module.
Convert the rightmost eight digits from hexadecimal to decimal. The result should be
a decimal number in the form, 84.xxx.xxx.xxx, where each group of xxx is a number
from 0 to 255. This is the default IP network address.
Installation Example: Discovering the Default IP Network Address
The following example shows the steps for discovering the default IP network
address.
Step Action
1 Locate the global address label on the front panel of the module.
2 Note the rightmost eight digits.
3 Convert them from hexadecimal to decimal. Each pair of hexadecimal numbers will
result in a decimal number between 0 and 255. This is the default IP address.
4 If you use the default IP network address and if your network uses Ethernet II framing
and if you do not need to specify the default gateway or a subnet mask, then you may
install the module without changing the default configuration.
CAUTION
System Error
Do not connect this module to your network until you have ensured that its IP
address will be unique on the network.
Failure to follow these instructions can result in injury or equipment damage.
