5.2 DLL (Dynamic Link Library) Driver

The ADAM-5000 API Dynamic Link Library (DLL) enables you

to quickly and easily write Windows applications for ADAM-

5000 systems. The library supports both C++ and Visual Basic.

Since ADAM-5000 systems communicate with a host computer

through the host‘s COM port, no additional driver (DRV or

VxD) needs to be installed. The DLL includes all necessary

function calls to utilize the ADAM-5000 systems to their fullest

extent.

Together with the DLL driver you‘ll find the source code of a

Visual Basic example on your diskette. The example provides

several control windows to communicate with all types of

ADAM-5000 modules. You can customize the source code to

create your own tailor-made

ADAM-5000 setup program or monitoring system.

For details on the ADAM-5000 function calls refer to the

Help file included on the ADAM-5000 API diskette.

5.3 DDE (Dynamic Data Exchange) Server

The ADAM-5000 DDE server takes advantage of DDE, a built-in

Windows communication service. The DDE server acquires data

from the ADAM-5000 systems and passes it to your

application program via the hot link (DDE). The software can

also pass control and configuration commands to the ADAM-

5000 systems using the DDE protocol. You can now use ADAM-

5000 systems with most Windows- based data acquisition

software that supports DDE. Examples include Intellution's

FIX DMACS, Wonderware’s InTouch, ONSPEC, Paragon and

Excel.

For details on the ADAM-5000 DDE server refer to the DDE

server manual for the ADAM-5000.
