Dear Marco, Because the PN-CPUs (both that you have) are working normally with Open Communication please download the OC Wizard and make the communication with that wizard. Wizard for creating connection data for open TCP/IP communication (Open Communication Wizard). You can find more information about the blocks in the manual where all FBs are described. System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 Look for the TCON/TSEND/TRCV/TDISCON FB63...66. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
