--------------------------------------------------------------------------------

Dear Abacom and Users.

Up to now I have used PL to communicate with my Microcontroler based applications over the serial Port and by using the Microchip CDC class windows driver emulating the serial port I use the USB to communicate.

I was just thinking and excuse any techincal statements which is incorrect as I am not that familiar with the PC side.
any how If I could use PL to access the TCP (LAN Card) I could use the
ENJ ethernet controller and through the ethernet communicate to my application microcontroller (applying the TCP protocol)
is this any way sensible to do or completely incorrect,
I need in a application to transfer rather large data blocks to the PCapplication.(I do not want to do an internet application it is a pure communication between PC and application Hardware).
any views or advise is highly appreciated .

Regards
Peter

Not yet. ProfiLab uses its own protocol (over TCP) to exchange data between two ProfiLab applications. Not made for user applications.
For your purpose better write a DLL!

Dear Abacom

Thank you for the reply!

As mentioned I am not that familiar with the PC side
is it possible to use a DLL to connect to the LAN port on the PC !!
Please help I am completely confused here .

I will start by looking at the PL examples on the use of DLLs

Best Regards
Peter

The "DLL import" component is a programming interface (API) for ProfiLab Expert. Inside the DLL you can do any kind of calculation (typically communication with hardware). Also refer to:

dll-import---programmierbeispiele-t328.html

See ProfiLab examples as well. If you are familiar with C, the DEV C++ compiler (open source, freeware) may helpful for a first approach.

Dear Abacom

Thank you for the reply ,
I am familiar with C as I use C to program the Microcontrollers
I will take alook at the link you included.
Thankyou very much for the advise

Dear Abacom and Users

Is it also possible to write a DLL in VB.net 2005.as the express addition is for free and I have VB.net standard as we also use it to program NI hardware with VB.net and NI measurement Studio
if this is possible it might be for me the easier ways as said before I am not that familiar with the PC and windows Programmimg.
Best Regards
Peter

I´ve tried the VB.net 2005 free version as well before. It is NOT possible. What you need to create is a simple DLL function library. VB.net handles DLL´s as type libraries, which is something completely different!
