Hi all, Pretty new to Modbus, how do I set up this register to be displayed in tag browser? I tried ns=1;s=[Power Meter N2]HR1700 but no luck. [image] [image] Appreciate all your insights! PM800 Register List FMW_11.500_P.pdf (1.9 MB)

I actually have some pm800 series meters and had to figure this out. I read the 4 registers in a UDT and then created an expression tag to combine them. ({[.]kWh_Reg4}*10000^3 + {[.]kWh_Reg3}*10000^2 + {[.]kWh_Reg2}*10000 + {[.]kWh_Reg1})/1000 How to convert Mod10 (modulo 10000) register…

1700 is de energy input from like solar. I think you where looking for 1708 energy Real Out. Dont forget that the data type is WH from modbus, KW is showing in the dashboard.

Do you get any value? Zero addressing can also be checked by setting the adress on 1707. Does the GW show any errors?

[image] Rick_de_Man: ns=1;s=[Power Meter N2]0.HR1700? This should likely be: ns=1;s=[Power Meter N2]1.HRD1700

"mod10" is a Schneider-specific multi-word encoding for very large numbers. It is not supported by Ignition's native driver. You can bring in the individual words as separate tags and construct the composite with an expression tag. This data type is directly supported by my alternate driver.

how do you set up the opc path of each Kwh_Reg?

Thanks all Apparently it should be 1.HR1700 , then 1701..1704. Then use josborn's xpresion to come up with total kwh.

Hi all, Just encountered to another issue. When I tried to create a OPC 1.HR1700 to one power meter, its modbus connection keeps disconnect and connect. The other one is fine! Log saying Modbus TCP Socket Connection Closed, DriverState was Connected

Edit: mod10 should be a floating value

How to read Mod10 registers Ignition

Hi, I'm trying to read energy registers from a CM3000 on Modbus TCP/IP, can ignition read Mod10 type registers? [image]
