All Register of ION7650

[sesa101974_brid]

HI all,

Can you give all register list of ION7650.

ION7650 use Ethernet port.

Thanks very much

All registers on 7650 or all the measurements being logged?  7650 has thousands of registers.  What is the application you are trying to do?

Hi Huang,

I want know name register Power Factor Displacement in ION7650?, because I see in ION7650 have PF sign, PF Leading, PF Lagging.

More can you explain difference PF Leading and PF Lagging.

Thanks very much

David Tuckey​, can you explain the difference between PF Leading and Lagging?

HI Huang,

Thanks very much

HI Tuckey

Please help me

Thanks very much

My short answer is that all of these registers (PF sign, PF lead, PF lag) are different formats for what amounts to total power factor (by definition, based on the full measurement bandwidth); none of them correspond to displacement power factor (by definition, based on the fundamental component only).  If you are interested in the displacement power factor, it would be possible to derive it in the ION framework using data from the Power Harmonics module, but that requires some custom ION programming and it is not available in the default ION framework for the ION7650.  The PM8000 does provide this measurement in its default ION framework, and the logic would be similar for the ION7650.

For your understanding, here is a brief description of the existing registers.  "PF sign" provides a signed value between -100 and 100, where the sign convention is configurable as either IEEE (leading=+, lagging=-) or IEC (follows the sign of real power).  "PF lead" is an unsigned value (either 0 to 100 for leading power factor or N/A for lagging power factor).  "PF lag" is also an unsigned value (either 0 to 100 for lagging power factor or N/A for leading power factor).

I would recommend the "ION Reference" document as a resource to help with this type of question, looking specifically at the description for the Power Meter module for this topic:

ION Reference -EN | Download Schneider Electric

Here are some excerpts from that document, referring to the descriptions within the "Power Meter module".
