CTI 2572 Installation and Operation Guide

1.8. Getting Started
Assigning an IP Address
Before proceeding you must determine what IP address you will assign to the module. If you are
connecting to an existing network, your network administrator will provide this information. If you
plan on connecting your network to the Internet you should contact the Internet Network Information
Center (NIC) for IP address assignment. If you are installing a stand-alone network, you may choose
any set of IP addresses as long as they adhere to IP addressing conventions. See Appendix E of this
manual for a description of the IP Address numbering conventions.
Choosing and implementing a Module Startup Method
Before the 2572 will accept TCP/IP messages, the module Network Server must be started. You can
use PLC logic to assign the IP address and to start the Network Server or you can have the module
automatically start the Network Server using an IP address stored in the 2572 EEPROM. See
Chapter 2 for a description of these methods. If you choose to use PLC logic, you will need to create
a command block and incorporate a few rungs of ladder into your program. See Section 2.6. Using
PLC Logic to Start the Network Server on page 19.
Setting Module Switches
Module dipswitches configure the serial ports and select the startup method. See Section 2.4. Setting
the 2572 Switches on page 14 for a complete description.
Installing the Module in the PLC I/O Base
The 2572 is a single wide module that installs in a standard SIMATIC 505 PLC rack. For best
performance you should install the 2572 in the first I/O slot of the local base. Chapter 2 describes
unpacking and installation of the module.
Logging the Module in the PLC I/O Configuration
When you initially install the module in the PLC I/O base, you must log the module into the PLC I/O
configuration. The 2572 logs in as 2 WX and 6 WY words. See Checking PLC Login in Chapter 2 on
page 18.
NOTE:
The module will not operate properly until it has been logged in.
Connecting the Module to the Network
You can choose to connect the module directly to 10BaseT cabling or, via a transceiver, to any IEEE
802.3 compliant media. See Section 2.8. Connecting Cables on page 26.
Checking out the Module
You can use both the module indicators and commonly available software to ensure the module is
operating properly. Section 2.9. Module Checkout on page 27, describes these procedure. Chapter 4
also describes the module operation.
