INTERBUS DDE Server

The Klinkmann Automation INTERBUS DDE Server is a Microsoft Windows (3.x or NT) application program that acts as a communication protocol Server and allows other Windows application programs to access input/output data from INTERBUS devices. Any Microsoft Windows program that is capable of acting as a DDE or FastDDE Client may use the INTERBUS Server..

There are following INTERBUS Server versions available:

- INTERBUS DDE Server (32-bit), can be used on MS Windows NT.

FEATURES

The Server communicates with INTERBUS devices via the IBS PC ISA SC/I-T controller board, installed in an IBM-compatible PC.

The Server uses Device Driver Interface functions, supplied by Phoenix Contact, to access controller board via Process Data Interface.

IBS PC ISA SC/I-T controller board parameterization data must be created with IBS CMD SWT G4 tool and written to board parameterization file. The Server loads this parameterization file to board, when DDE communication is started by Client.

Up to 512 devices can be accessed.

Up to 4096 I/O points can be accessed.

The Server supports multiple topics, allowing different data update rates for various DDE items.

The Server provides a communication status flag for each topic.

Supported DDE item types are Inputs and Outputs. Inputs and Outputs can be accessed as bits, bytes, words or double words (signed or unsigned). Item/point naming uses byte-oriented addressing. The following table describes item/point naming conventions:

Notes:

1. b - specifies byte address (0 to 511);

w - specifies address of word's higher byte (0 to 510, even number);

d - specifies address of double word's higher byte (0 to 508, even number).

2. For Bit data: x = 0 ... 15.

3. Inputs are Read Only and their {Prefix} is I or E (Eingang).

4. Outputs are Read/Write and their {Prefix} is Q or A (Ausgang).

Alternative item/point naming is supported, to enable use of old InTouch/other applications, earlier using other DDE Servers and INTERBUS boards. Alternative item/point naming uses word-oriented addressing. The following table describes item/point naming conventions:

0 to 65535

Notes:

1. w - specifies word address (1 to 256).

2. For Bit data: x = 0 ... 15.

3. Inputs are Read Only and their {Prefix} is INPT.

4. Outputs are Read/Write and their {Prefix} is OUTP.
