An IP Address can be assigned to the ERM module or its slaves if your network requires one.
Normally, a network administrator will assign an IP Address to each device on the network.
Since it is recommended to use a separate dedicated network for your ERM , you do not have
to use the IP Address, unless you are using the UDP/IP protocol. Use the Module ID or
Ethernet Address for each module when using the IPX protocol. You can use NetEdit3 within
the ERM Workbench utility to give the ERM or its slave modules an IP Address. Each ERM
and slave must have a unique IP Address.
The module ships from the factory with an IP Address of 255.255.255.255. This is not a
usable IP Address for normal communications. It only serves as a default setting which can be
changed using NetEdit3. The valid settings are 0 through 254. You do not have to change
the default IP Address unless you are using IP Address protocol. The default setting does not
cause conflicts with other network communications. If you change the default IP Address for
linking to other network devices, you must change all four “255” fields. If any field contains
the number 255 and other fields have been changed, the module will not be recognized on the
network.
Example IP Addresses
• 192.168.55.5 - Valid IP Address
•
255 .168.55.5 - Not Valid
WARNING: It is extremely important not to have duplicate IP Addresses on your network. If you are
using the IP Address, all modules must have a unique number.
A unique Ethernet (MAC) Address is assigned to each module at the factory and will not
change. It is printed on a label attached to each ERM/EBC module. The Ethernet (MAC)
Address is recognized by NetEdit3. The Ethernet (MAC) Address is a twelve digit number
with no deliberate relationship to your network or functional areas of your plant. Typically,
the MAC address is not a convenient and easily remembered identifier for your ERM/EBC
module.
You can use IP Addresses to satisfy network requirements and Module IDs for PLCs to share
data among themselves. Using one type of identifier does not limit your use of the other
identifier types.
