Hello dave,

giving 5 stars to your work  perfect!

Hello Expert,

I have tried Sharp7 to connect to my S7200 Smart PLC, CPUST20 on Ethernet.

I have tried your demo project in C# as well as in VB. The one that you have shared in the Sharp7 packages.

Please see the attached snapshots that will explain you the error message that i am getting in receiving error.

I would request you to guide me if there are some changes required for S7 200 Smart.

Let me know the solution of my problem.

Thanks in advance.

Hi Sushil,

S7200 and LOGO 0BA7/0BA8 connections are a bit different from the ones for S7300/1200/1500.

You cannot use ConnectTo(IP, Rack, Slot) but you must specify the TSAPs.

So the sequence is:

SetConnectionParams(IP, LocalTSAP, RemoteTSAP);

Connect();

Sharp7 is the port of Snap7, into the doc you will find only the method references, please refer to Snap7 documentation (online or PDF offline) for info about connections, protocol and so on.

There is a chapter dedicated to S7200, Here you will find how to use TSAPs.

Regards
