OPEN COMMUNICATION INTERFACE (OCI) DDE Server

The Klinkmann Automation Open Communication Interface (OCI) DDE Server (OCI_DDE) is a Microsoft Windows application program that acts as a communication protocol Server and allows other Windows application programs to access data from Phoenix Contact Open Control system using the Open Communication Interface (OCI). The OCI_DDE Server requires some IBS ISA FC... family card (e.g. IBS ISA FC/I-T or IBS ISA FC/486 DX/I-T) and KW Software PC WORX program to be installed on the IBM compatible personal computer (PC).

Any Microsoft Windows program that is capable of acting as a DDE or FastDDE Client may use the OCI_DDE Server.

FEATURES

The IBS ISA FC... card and PC WORX software should be installed on the PC and PC WORX project created and the 16-bit KW Software DDE Server (OCISRVR.EXE) should be started before OCI_DDE Server.

Minimizes system message traffic by dynamically calculating and optimizing poll lists for client-requested items/points.

Supports multiple topics for each PC WORX project channel, allowing different data update rates.

Provides a communication status flag for each topic.

Supports standard DDE among multiple applications.

SPECIFICATIONS

Hardware: IBM or compatible 386/486/Pentium equipped with a minimum of 4 MB RAM (16 MB RAM for Windows NT). May require more memory to run other Windows programs simultaneously.

Software: Microsoft Windows 95 (98) and Microsoft Windows NT 4.0.

Computer Interface: Phoenix Contact IBS ISA FC... family card (e.g. IBS ISA FC/I-T or IBS ISA FC/486 DX/I-T).

Accessible Point Types: The DDE item/point naming system used by OCI_DDE Server fully corresponds to the naming system used in OCI interface for accessing to PC WORX project variables. At OCI_DDE Server startup it reads the corresponding PC WORX project SR.CSV file and uses the names of global variables from this file to validate the names of DDE item/points requested by the client (e.g. InTouch or Excel) application. Also the corresponding type of DDE item/point (DDE Discrete, DDE Integer, DDE Real or DDE Message) is obtained from this file

The name of DDE item/point can be without or with global variable prefix @GV., for example, both following DDE item/point names are valid: T311_X or @GV.T311_X..
