Hi everyone,

i am really sorry for asking a question again in forum. But its really a big problem and i am not able to solve that.

i created a client fb in 4diac and want to test the communication with Kepserver. i found, that the client fb can only receive the data (here S7.1500.Aus). However the FB can not send a data (Here S7.1500.Ein) to the Server.

After triggering the REQ i could not see the data in Kepserver.

in Addition i post the picture during compiling the forte project in visual studio. I saw here really many warnings, which all have LNK 4254 to do. Can those warnings be a reason for failed communication?

Hope someone can reply
thanks
