ok, thank you for your support ! now I was able to use the function blocks for UDP open, send and close

1) I already tried with &0 , &1 , &12 , but always with the same result 2) I see ! now I understand why it doesn´t works. Thanks for your support.   kind regards, Michael Malsch

thanks for your reply here is the (reduced) program now only the "wake-on-LAN"-sequence is still inside   I tried to open an UDP connection with the internal ethernet card at the CPU, but the function block gives always the result NG with error code 1025. What is the reason ? What is wrong ? Made the test with unit number 1 (as used in the hardware config) and with 0 (in the manual I could read that the internal board needs a 0). But always unable to open the UDP connection. LP2100_32_20181113_UDP.cxp

Does anyone have a simple example for download to see how to make a UDP connection ? I want to make a connection to a NAS harddisk system for wake-on-LAN. I used the UDP_open, UDP_send and UDP_close function blocks. But UDP_open gives always the result NG with error code 1025. I can´t find the reason why it doesn´t works.
