Dear Murof,

                    I used a TIA V15 with PLCSIM V15 & wincc 7.4 with simatic net V14 SP1, WHEN I put Tia v15 online it goes online but when i open wincc & Select 1200/1500 In tag management & under OMS take a New connection & Set IP Select S7-ONLINE, Select 1500, At the tag management on the left of new connection under OMS, it does not show a GREEN TICK, It shows two orrange vertical tick means their is problem of communication between TIA V15 & wincc 7.4,

Please Help.

Hi,

I have exactly the same problem with the same configuration.

I can't find a solution.

BUT, when I try the same with a complete configuration S7-1200 (in TIA and in WinCC) it's work ?!

Best regards

Hi,

Problem solved with WinCC 7.4 SP1 UP1.

Now communication with PLCsim is possible with S7-1200 and S7-1500.

thx
