The object contains data extracted from one column of the CHRONOA object's data array. The data, once extracted, can then be submitted to other objects for further calculation.
A new DATACOL object is automatically created by the call to Pv.DataCol(). It is usually transient, existing only for one function call.
|DataCol = Pv.DataCol(ColumnCode)|
|DataCol||DATACOL||The new object containing the data extracted from the PV data array.|
A code identifying the column to be used.
0 = Time
1 = Applied Forward Voltage
2 = Applied Reverse Voltage
3 = Applied Step Voltage
4 = Measured Current
5 = Measured Forward Current
6 = Measured Reverse Current
7 = Measured Current Difference between Ifwd and Irev.
8 = Applied Signal
9 = Measured Aux Channel Voltage
Or use the predefined constants:
PV_T = Time
PV_Vfwd = Applied Forward Voltage
PV_Vrev = Applied Reverse Voltage
PV_Vstep = Applied Step Voltage
PV_Im = Measured Current
PV_IFwd = Measured Forward Current
PV_Irev = Measured Reverse Current
PV_Idif = Measured Current Difference between Ifwd and Irev.
PV_Sig = Applied Signal (V)
PV_Ach = Measured Aux Channel Voltage
