8.1.3.3.1 How to calculate Modbus Scale Low / High
❖ Get Scale low and Scale High from Recorder AI Configuration
❖ Calculate ΔScale Range,
ΔScale Range = Scale High - Scale Low
❖ Calculate Modbus Range
Modbus ΔScale Range = ΔScale Range * 1.2
❖ Calculate Modbus Scale Low = Scale Low - (Modbus ΔScale Range - ΔScale Range)
❖ Calculate Modbus Scale High = Scale High + (Modbus ΔScale Range - ΔScale Range)
❖ Convert the Modbus Scale Low / High value to DWord value using the below formulae.
For example:
Scale Low is 500, Scale High is 1000
ΔScale Range = Scale High - Scale Low = 1000 -500 = 500
Modbus ΔScale Range = ΔScale Range * 1.2 = 500*1.2= 600
