RTU Slave Interface Displaying 4 Decimals Instead of 8
8_decimal Point Kwh data On MFM Display, Displays as only 4_Decimals On SCADA User Interface Screen
By sultanalam2 on 5 January, 2017 - 6:52 am

I am Facing Problem Getting Kwh Readings From My Satec MFM (PM130-PLUS), Required for an easy & reliable Monitoring On Energy Consumption.

Connected via RTU Slave Interface with SCADA User Interface (GE_Cimplicity).

Here's what happening:

Actual Kwh Reading has 8_decimal Point/digits on MFM Display but on SCADA User Interface Screen It only Displays 4_Decimals/digits,

eg, 15270156 kwh shows as 156

and 63290058 kwh shows as 58

and 15299999 kwh shows as 9999

and 15300001 kwh shows as 1 only!

Is It something to do With the Holding Registers or Extended Registers Functions??

Please Do a Reply, your slight approach to my Query Will be highly Appreciated :)

Kindly screen shot your exact complain and forward to charlesndphc@gmail.com to enable me help properly.

Thanks

have you perhaps configured that display as only being 4 characters wide?

Not necessary,
If this problem has always existed. It has to do with the register size format in the read function of SCADA configurations.
