All,

I have a project that requires using Modbus control of the Rockseed RS310P.

My requirements are relatively straightforward, but I have been unable to
get past *go *on my own...

If I can open a session from Python and generate a sine wave with:
- freq ==> w == [0.15 .. 60.35] Hz
- amplitude ==> k == [0.75 .. 5.30] V
- phase ==> phi == [0.0 .. 2*pi] rad
- DC offset ==> offst == [0.0 .. 2.34] V

My tests will be short, and the other parameters of the test will be:
- t_delay ==> [2.0 .. 15.0]
- t_duration ==> [15.5 .. 30.0]

v_sin = k * sin( w + phi) + offst;
v_test = (t >= t_delay) * v_sin * (t <= t_duration);

If I can achieve a 100Hz update rate (0.01sec between Modbus command
messages to the RS310P), I think I will get close enough to the 65.35 Hz
sine wave frequency requirement.

Any help is appreciated!

Best regards.
