CTI 2572 Installation and Operation Guide

CHAPTER 2. INSTALLATION
The installation of the Model 2572 Ethernet TCP/IP Adapter Module consists of the following steps:
1) Planning the installation,
2) Unpacking and configuring the module,
3) Physical installation,
4) Setting IP information,
5) Connecting cables,
6) Checking the module operation.
2.1. Installation Planning
Ethernet Media
The Model 2572 attaches directly to 10BaseT media (Unshielded Twisted Pair) via the RJ-45
connector. You should select cabling rated CAT 5 or better. Should you choose another Ethernet
medium, you must obtain the appropriate transceiver to attach to the AUI port. Ensure that the cables
you use for Ethernet communications meet the IEEE 802.3 specifications and are appropriate for the
environment in which you are operating.
NOTE:
Check your cabling carefully. Faulty cables and/or connectors are the
leading cause of Ethernet communications problems.
Serial Communications
The serial ports on the 2572 module are provided for configuration and diagnostic purposes. For
typical applications, you can use a standard serial PLC programming cable. Although you may use
the ports to access the PLC, applications or devices that place a heavy transaction load on the module
will degrade network performance. If you have a need to service these devices, consider installing a
separate CTI 2573 module.
Establishing Network Parameters
Before the 2572 can communicate on a TCP/IP network, you must establish the network parameters.
These include an IP Address and Subnet Mask for the module, a TCP/UDP port number for the PLC
Network Server function, and, if your network contains a router, the IP address of the Default Router.
See Appendix E for a complete description of TCP/IP address nomenclature. You may also wish to
refer to general publications describing TCP/IP.
You have a choice of two methods for establishing the network parameters. One method allows you
to use the PLC program to set the IP address and other network parameters. The second method
