HI,

I have a problem with a UDP comm in a S7-317 2PN/DP with integrated IE PORT.

I am using FB TCON and FB TURCV (I only need receive UDP telegrams).

When I try to connect (REQ input), the status is 7000 and the bits NDR, BUSY and ERROR remains in FALSE value.

I fill the data connection correctly, but the TCON NOT FUNCTION. 

With the TURCV block, when I start to receive (EN_R) the STATUS change from 7000 to 7002, and the busy bit is in TRUE value. 

I dont know where is the problem. 

I will appreciate some help about this topic. 

Thanks.
