CTI 2572-DDS2 I/O Server

Description

The CTI 2572 I/O Server is a Microsoft Windows program that allows

compatible client applications to access data stored in CTI 2500 Series

or Simatic® 505 PLCs. The server communicates via TCP/IP to a CTI

2572 or 2572-A TCP/IP module installed in the I/O base, or via the

built-in ethernet port on a CTI 2500 Series controller.

The I/O Server is intended for use with Wonderware application

software, including Factory Suite 2000 applications. It supports

Wonderware Fast DDE, Net DDE and SuiteLink. However, any Windows

program that is capable of acting as a DDE client, such as Microsoft

Excel, can also use the facilities of this program.

NOTE: 2572-DDS2 IS NOT SUPPORTED FOR WINDOWS VERSIONS

AFTER WINDOWS XP, AND IS NOT SUPPORTED FOR WONDERWARE

VERSIONS ABOVE V8.0. FOR COMMUNICATIONS SERVERS FOR

WINDOWS 7 AND WONDERWARE 9 OR ABOVE, WE RECOMMEND

CHANGING TO CTI 2500-OPC KEPSERVEREX OPC AND

COMMUNICATIONS SERVER.

The CTI 2572 I/O Server maps a Topic to a corresponding TCP/IP

socket. Each socket represents a logical connection to a 2572 module

or CTI processor. A socket can use either the UDP or TCP protocol.

Multiple topics can be assigned to the same 2572 module or CTI

processor and each topic can be configured for a different polling

rate. Thus, a system designer can group data points by topic to

optimize update times for each group.

In addition to polling for data, the CTI 2572 I/O Server will also accept

unsolicited mes sages from the 2572 module. Standard PLC logic can

be used to initiate these mes sages, which may contain event-based

data, such as alarms. This capability reduces the polling load and

potentially reduces the latency in reporting events.

Features

• Enables access data in 545. 555. and 565 and CTI 2500 Series PLCs

• Communicates with one or more 2572. 2572 A modules, or CTI

processors using the TCP/ IP protocol.

• Supports multiple topics per CTI module.

• Accepts unsolicited data messages, elimi nating thepolling overhead

for event-based data items such as alarms.

• Interfaces to multiple clients and coexists with other I/O servers.

• Supports high-speed Fast DDE, Net DDE, and SuiteLink protocols when

used with Wonderware FS2000 products.

• Provides data time and quality information when used with Wonderware

SuiteLink.

• Includes option to run as an NT Service.
