Whole Number issue with Integrator Module

Dear All,

In ION 7650 Power Logic Meter, the Integrator Module is calculating the KWH from KW Total. This KWH is displayed on the Meter with two decimal places, e.g 99999.XX

But, when we link the output of this Integrator module with a numeric element or any other module inside the Meter Framework, the value read is a whole number without decimal places.

E.g if you have 99999.XX, you will read only 99999 in Vista.

Even if you try to read the value on the output of this Integrator module, it is showing a whole number.

Any idea as to why this issue is appearing?

Regards.

Re: Whole Number issue with Integrator Module

It depends on how the Modbus register is configured.  If the data is formatted to any of the following, U16,S16,U32,S32 then the data is integer only and any decimal value is lost (I'm not sure if it is rounded or truncated)

To "retain" the decimal you can apply scaling at the Modbus module level.  For example if you apply a x100 scale on the Modbus output then apply  / 100 to the register in the MDI or translator you "gain" of resolution.  This however can cause overflow if the original inpout value gets to big.

Re: Whole Number issue with Integrator Module

Hi Salman,

Is this meter being read via ION protocol, or modbus?

Re: Whole Number issue with Integrator Module

The default Vista diagrams are set to display "0" digits after the decimal place on the Energy and Dmd screens.

You can change this by right clicking on the Vista object and selecting the "Display" tab of the "Numeric Object Configuration" window and changing the "Resolution" value to the desired number:

Re: Whole Number issue with Integrator Module

The meter is reading on modbus protocol.the issue what we are facing is the output of the integrator module is a whole no (which should show me a decimal value ).when the value is being linked to a display screen. The value now shows in decimal. Any reason for this changeover?
