I have placed RTM75 in same phase as PLC, it is working as before but
my PLC is still not getting the feedback. If we think 50Hz frequency
is the factor responsible then taken as a whole it should not work.
The room is small test lab type where all these setup resides with one
step down transformer also in the room. The room is entirely closed
one with glass door.Is the noise on line may be a reson. I am making
use of step down transformer since the supply available is 240V
Thanks

I think most, if not all, X-10 made devices merely react to the line
frequency and do not care whether it is 50Hz or 60Hz. It's only for the
other two phases that it has to calculate the zero crossing times. It can
only sense the phase into which it is plugged and must calculate the others.
Anyway, the fact that it operates the lamp indicates the transceiver is
sending powerline commands OK.
Other things can cause problems. Read this page for a brief introduction to
noise and signal strength issues.

Jeff Volp has written a more detailed X-10 trouble-shooting guide. There is
a link to it on the above cited page.
