Hi,
You are right, there are 3 transmissions per zero crossing. The first is almost at the zero crossing, the second and third 2.778 ms and 5.556 ms later (in a 60 Hz environment) respectively. These last two are transmitted solely to cater to receivers which might be on other phases, and which would therefore see their zero crossings 2.7 ms and 5.56 ms later (again as per 60 Hz) .

Therefore, as long as the transmitter and receiver are on the same phase, they experience the zero crossing simultaneously, and the frequency itself is immaterial.

Well the first takes place 2.778 ms after zerocrossing for 60hz
To get this working properly it needs to be 3.3333 ms for 50hz

So even if you use one phase and the same phase this timing needs to be correct

No, you're mistaken here; if you look at the graph, you'll notice the first transmission is *at* the zero crossing. The 2nd after 2.778 ms, and the 3rd after 5.556 ms. The next *zero crossing* happens after 8.33 ms (or 10 ms in the case of 50 Hz), but this is irrelevant as no transmission happens at this time. Anyway, trust me, the TW523 does work happily on 50 HZ.

Regards,

Anand.

Hi

With some support of Melabs i changed timings in the
PBP lib file and correct them for 50hz

Now X-10 is working

So timing is important, even if you work on a single fase

I now will work on Xin with Melabs

Will post if its work
