PM5560 Polarity

[arjanbijker]

Hi,

With the PM800 you could change current polarity settings via modbus commands.

Can the PM5560 do the same?

We have a whole bunch of them installed in datacenters where it is not possible to shutdown power that easily.

That is a very good question, Arjan.

The PM556x_ModbusRegisterList shows the needed registers (ref. to "Logical Phase" ...) similar to PM800 series, however the command sequence is different.

Perhaps , can help.

Hi Arjan,

Can you explain how to change CT polarity with Modbus command? What type of meters that we can do that?

Thanks & Best regards,

Tran Bao Duong

Sorry but I don't see any document with RESL210828. Maybe I'm not authorized to access this link.

Unfortunately, you can not change the current polarity through modbus commands in PM5560.

[VictorMarincus]

So there's no way to do that? I am surprised.

Then the register list for PM556x is inconsistent.

Why a conditional write is mentioned then on the "[DEAD LINK /message/12539#12539]PM556x_ModbusRegisterList_V1.0.02-Public version.xlsx"?

Hi Victor,

Discussed with L4 product prime regarding modbus commands to change current polarity in PM5560. Thanks for above screenshot with register details. I will discuss again and will get back to you with the latest updates.

Thanks for pointing those out Victor.  I missed them on my pass through the register list.

Hi Victor,

These registers are not configurable.
