Relative Setpoint in ION7650 Doesn't support High Speed?

[Leah_Sun]

Hi All,

We need to build a framework in ION7650v410 meter, which compares two high-speed readings so we thought relative setpoint module might be the right one. However, we found out that it doesn't support high-speed which surprises us.

Based on the ION Device Template Reference (we really need a new version!), some "legacy" meters like 7700 and 7600 support high speed, and the normal setpoint module also supports high-speed mode in ION7650.

So, anyone knows why it is not supported? Or if it is not possible can we at least make the module force to change the input to 1 sec speed?

Thank you very much

What value you want to compare ?

For electrical measurement the regular Power Meter Module update output every 1 sec. we measure electrical value base on 1 Ampere = 1 Coulomb/sec.

Hi Yut,

Thanks for the reply, we need to compare the output either from PQA module or HS Power Module for Sag/Swell PQ Event. Although the meter has some related modules already, we do want to build some specific framework which can compare these high-speed values (1 cycle), as Sag/Swell can be as fast as several cycles.

Since the normal Setpoint Module can take these high-speed inputs, we are just wondering why the Relative Setpoint module cannot do it.
