PREFACE
This Installation and Operation Guide provides installation and operation instructions for the CTI
2572 Ethernet TCP/IP Adapter Module. The information in this manual is directed to individuals
who will be installing, maintaining, and troubleshooting the module.
We assume you are familiar with the installation and operation of:
1) SIMATIC® 505 programmable controllers,
2) Ethernet local area networks,
3) Transmission Control Protocol/Internet Protocol.
Please refer to the appropriate SIMATIC® user documentation for specific information on
SIMATIC® 505 programmable controllers and I/O modules.
If you plan on developing on writing computer applications which interface to the module via TCP/IP
you should also obtain the CTI 2572 Programming Reference Manual (CTI Part # 62-166), which
provides detailed information on the module command message interface.
