Hello,
I made simple modbus client in C# and it works....But there is one problem,when I try to connect first time it will not connect then after 5s I will do it again and it connect perfectly....same when I shut down connection and then try to reconnect always works on second attept...I thought that I made some mistake,so I try to use Modbus poll utility and the same result,with Labview also...Can it be problem with simatic firmware /my is 2.2/?
I thanks for all anwers.Thanks a lot...
