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.
