Control Technology 2500-C CPU Series Tech Tip

Setting the IP Address on CTI Products
SUMMARY
In order to use any CTI product with Ethernet
connectivity, you must first set its IP address. This Tech
Tip will provide simple instructions for setting IP
addresses for both initial use as well as replacement use
for the following products:

2572-A

2572-B

2500P-ECC1

2500P-ACP1

2500-Cxxx CPU
More detailed instructions can also be found in the
respective user manuals for each of the products.
Before You Get Started
All of the above CTI Ethernet-connected products require
a fixed IP address. Before installing your module, you
need to determine its IP address. If you are connecting
to an existing network, you should obtain an unused
static IP address and the network subnet mask from the
network administrator. If you are establishing your own IP
addresses, you should select IP addresses from a block
of 'private" addresses
Internet Assigned
established by
Numbers Authority
The private address blocks are:
• 10.0.0.0 through 10.255.255.255 (Class A)
• 172.16.0.0 through 172.31.255.255 (Class B)
• 192.168.0.0 through 192.168.255.255 (Class C)
These addresses will not be forwarded by the Internet
backbone routers; therefore, you are free to use any
address in this group as long as it does not conflict with
addresses already in use at your local facility.
Please note that some methods for setting IP addresses
described here require your PC to share the same
network address and subnet mask (but not host address)
as the module connected to it and that the ECC1 and
ACP1 (if using data cache or CAMP client) require that
your CPU/host controller have the same subnet mask
and network address as the module in order to function
properly.
between network address and host address in most
situations, please see the following table:
the For more information on IP addressing, please see
(IANA). Appendix B of this Tech Tip.
