Hi Nassos
Did you used the plausibility check before starting simulation?
If I am right you have used the coils several times. One coil can only be used once.
If you are using analog inputs they can't be used as binary inputs as well (either or).
I don't know what the Ax NO and NC contacts are used for, should this be digital inputs? Digital Inputs are usually I1 ... I12.
If your Hardware has version 8 and the Software only offers 1 or 10, then you have to choose Version 1.
