It's a bit embarrassed to admit I have not done your basic work well enough. I asked for IP address and got 172.24.12.180 but it was the little sister machine that no extra CPU has but otherwise has the same hardware. I cross checked the CPU one and the communication card was in the right places as well as type a thought about wrong IP did not touch me at all. A look at the Siemens hardware setup of the communication card, on the big sister, showed that it had 172.24.12.190. Change IP to 172.24.12.190...

Thanks for fast reply but my friend went on a summer vacation so I can’t make test before he returns. Connection is made via CP-443 Ethernet communication card (slot 4) which will probably automatically respond to ping There are 2 wincc panels in the plant. Number 1 only has access to CPU1 but number 2 has access to both of them. I will test with client demo as soon as I have access to the system again.

I really like your tool. No big arm movement really good documentation. I have used Snap7 before using the Siemens 315 CPU without any problems. Just straight forward, perfect. But this is the S7 400 series and here there are 2 CPUs. 416F-2 and 412 I'm using Delphi EX7 32Bit Windows 7 Code while not Terminated do begin Cli:=TS7Client.Create; res:=Cli.ConnectTo('172.24.12.180',0,7); while not Terminated and (res=0) do begin sleep(200); res:=Cli.DBRead(209,500,sizeof(fis),@fis); readdata:=swapread(fis);...
