It seems like there is an error in TIA V13 upd1, regarding parameterizing the new TCON function for S7-1200 V4.0. According to the Online Help in TIA V13 upd1, you are supposed to use the new Connection parameter structure called TCON_IP_V4, when working with S7-1200 PLC's with firmware 4.0. The help says: Please see the attached screenshot from help in TCON_IP_V4.png When I try to use the new Connection Parameter datatype on my TCON function, it fails with the Error: "Parameters of the function or the function block do not match the transferred formal parameters." See attached screenshot S71200_TCON.png. If I do the same in a S7-1500, it works correctly, as shown in screenshot S7-1500TCON.png. I have included the example TIA V13 project with the 2 CPU's. I have started a Support Request regarding this issue at Siemens Denmark (1-3420996116), but they replied, that I should expect that the Online help is unreliable. My problem is still not solved, because if I try with the old TCON_PAR on the 1217C, nothing happens. The TCON FB simply stays on status 7002:Connection is being established (REQ irrelevant). But no connection is ever established, and not error is shown. Has any of you tried and succeeded to use Open User Communication on S7-1200 V4.0? Attachment1217tcon.zip (2426 Downloads) |

And no, it still doesn't work, no matter what version i choose on the S7-1217C, with the new TCON_IP_V4 datatype. |
