CHAPTER 1. DESCRIPTION
1.1. Introduction
The CTI 2572 Ethernet TCP/IP Adapter is a single
wide I/O module for SIMATIC 505 controllers. The
2572 module connects to Ethernet local area networks,
enabling the PLC to communicate with other network
stations using the Transmission Control Protocol/
Internet Protocol (TCP/IP). Using the CTI 2572
facilities, suitably programmed network stations can
acquire data from the PLC, send data and programs to
the PLC, and exercise supervisory control over the
PLC operation. In addition, the PLC can use the CTI
2572 to access data in other PLC systems equipped
with a CTI 2572.
The 2572 attaches to all Ethernet media specified by
IEEE 802.3 including 10Base5 ("thick" coaxial cable),
10Base2 ("thin" coaxial cable), 10BaseT (unshielded
twisted pair cabling), FOIRL (fiber optic cable) and
10BaseFL (fiber optic cable). 10BaseT cabling can be
attached directly to the 2572 via an RJ-45 connector.
Other IEEE 802.3 media may be connected to the AUI
(Attachment Unit Interface) port via a user supplied
transceiver.
The 2572 module also provides two serial ports that
can be used for configuration and diagnostic activities.
Both serial ports can operate concurrently.
The 2572 module itself requires no customer
programming. All configuration options can be set by
module switches or written to module EEPROM via a
serially attached personal computer. Optionally, PLC
logic can be used to set module configuration and to
control the operation of the module.
