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.
