Hej Jesper

I think that 2500Euro is to most.

Do you know the protocol for S7/IP (S7-300) Kummunication ?
I will then make my own Active-X, I have allready make to a Omron CJ1 CPU (Ethernet card EN11)

Hej Jesper

Kan du ringe på tlf 20319428

Hvis du kender protokolen for Siemens S7 Ethernet
kummunication, eller et sted hvor jeg kan finde flere
informationer.
Jeg har Siemens Net Cd-rom, den beskriver dog ikke retgodt
hvordan protokolen er opbygget.

Hej Arne,

I don't know very much about the various S7 protocols, only from a users point of view.

Siemens probably keeps the specifications to themselves, as they dont want others to make competing products to their Simatic Computing software.

But there are a few who make DLL type libraries (not ActiveX) for S7, and they are not all so expensive:
