Hello

I have a s7-1512C CPU and have configured OPC UA on it. The factory were the CPU is installed is running there own custom software for data management and product handling. This software was written using VB6.

My current issue is that the software engineer is asking me for the SDK API or toolkit. I am very new to OPC side of things so i apologize if my questions seem silly.

I have read alot of the forum posts regarding OPC servers and clients and also watched the tutorial videos.

I have also read chapter 9 in the s71500 communication function manual. On page 202 the speak of a "OPC UA toolkit"

Can someone please tell me were i can find the SDK or API or Tookit.

The Only thing i have found is this

https://opcfoundation.org/developer-tools/samples-and-tools-unified-architecture/net-stack-and-sample-applications/

Is this the correct files he will need ?

Kind reagrds

Hello UCAB

perhaps you can try to use a UA gateway like:

_In VB6 there are examples available for OPC DCOM Clients

(But I Think its not a "nice" solution...)
