5.6 Output Commands – GG, GN, GT, GS

The following commands “Get” the Gross, Net, Tare and ADC (Sample) values from the LDM88.x
are available in floating point and integer respectively.


GG

Get Gross value

[ Register = 2000, Type = Float ]

[ Register = 2020, Type = Int32 ]

Master (PC / PLC) sends

Device responds

Result

GG G+01.100

Gros weight 1.100 d


GN

Get Net value

[ Register = 2002, Type = Float ]

[ Register = 2022, Type = Int32 ]

Master (PC / PLC) sends

Device responds

Result

GN G+01.000

Net weight 1.000 d


GT

Get Tare value

[ Register = 2004, Type = Float ]

[ Register = 2024, Type = Int32 ]

Master (PC / PLC) sends

Device responds

Result

GT T+00.100

Tare weight 100 d


GS

Get ADC Sample value

[ Register = 202A, Type = Int32 ]

This command gets the actual Analogue to Digital Converter (ADC) value. This can be useful
during development or when calibrating to see how much of the ADC range is being used.

Master (PC / PLC) sends

Device responds

Result

GS S+125785

AD-value = 125.785 d

For service applications it is helpful to note the GS values for the “no-load” or “zero” output and
when the “calibration load” is applied.
