I can't create communication address for TUSEND fb. Thank you for your reply. Suggestions: From image 1, the LEN input to the block should be the length of the data being sent correct, not 0? From image 2/3, those blocks may require the DBs to be created with standard s7-300/400 address rather than optimized. Try recreating the blocks (after looking at the LEN tag) non-optimized. What is the datatype for the ADDR input? Is a P# allowed there?

You can see the operation of TCON attached configuration. Do you wonder if there is a bug in creating the data block. Are there any sample application which related to UDP? Regards.

Ethernet Communication: Data Exchange S7-1200 <-> S7-1200 It's an exampleabout using T-communication blocks for ISO-on-TCP. Programming for UDP should be similar.
