User control or Dll for C#.NET to manage s7-communications


Thread Starter


Hi everyone,

Could You give me some information about where to get dll file or some user control for to create application which communicates to S7-315-2DP through CP5611 using s7-communciation protocol?

I tried to use "s732.dll"bu DllImport which comes with siemens softnet s7, but when I call s7_get_device or s7_get_vfd I get System.NullReferenceException!!!

perhaps I have not configured Cp5611 corectlly, so I would appretiate configuration steps too!

Thanks in advance.
