Question

Schneider IEM3255 energy meter and KepServer EX setup

Hi, has anyone had an issue with setting up KepserverEX to read the Modbus kWh address 45100 which is a 32bit float on a IEM3255 energy meter?  KepserverEX reads all the other registers such as Voltage & Current registers which are also 32bit float and returns the correct values.  It won't read the kWh value and just returns a Zero, I've tried toggling Modbus Byte Order, First Word Low, Zero-based addressing and all sorts of combinations. I've even set up a dedicated channel just to read kWh in case there are different settings for different registers but no good.
I've tried other SCADA platforms such as Ignition and this reads it fine, so I know I've got the right address.
Any help appreciated

Hello,

I suggest capturing Wireshark packets while reading the kWh tag from Kepware and another platform. Compare them to see what is happening at the wire level. Alternatively, you can open a support ticket and provide the captured file, which can be analyzed by a Tech Support Engineer.
