Hi, Mikko!

I read CGXDLMSRegisterMonitor object.

TX: 7ea01a020161321382e6e600c0018100150000100101ff020047747e
RX: 7ea0186102015285c1e6e700c401810001010600000000facd7e

But when i try get value by attribute index 2 (thresholds array) it returns octet string instead array of DLMS_DATA_TYPE_UINT32

Is it OK?

I think it should return…

I think it should return array like this:
in CGXDLMSRegisterMonitor::GetValue(CGXDLMSSettings& settings, CGXDLMSValueEventArg& e):

if (e.GetIndex() == 2)
{
e.SetValue(m_Thresholds);
return DLMS_ERROR_CODE_OK;
}

Hi Dmitry, Don't use…

Hi Dmitry,

Don't use CGXDLMSRegisterMonitor::GetValue. I believe that you are reading the meter.
You can get the thresholds using GetThresholds -method.

Something like this:

CGXDLMSRegisterMonitor rm;
Read(&rm, 2);
rm.GetThresholds();

BR,
Mikko
