CC-Link - MEASURED VARIABLES
Each measured variable has different engineering unit (Refer to the table below). For example, when 40000 is read at the
register 41 for the 1 – 2 delta voltage, the actual voltage value equals to 400.0V = 40000 × 0.01, as the engineering unit for
this item is V/100 (0.01V).
Readable range for each parameter depends upon the parameter type, as shown in the table below. For example, Current
unit is applied to Line current or Neutral current, and Voltage unit is applied to the 1 – 2 delta voltage or the minimum value
voltage.
