|TopCon - power supply|
|A1||Overvoltage in open circuit state (approx. I=0A) when using AAP functionality.||
If Upreset of TopCon is bigger than max voltage of the I=f(U) curve AND the TopCon is not adequately adjusted (e.g. showing neg. value when no current output), the voltage controller cannot work, hence voltage is restricted not by the AAP curve, but by Upreset
→ Set Upreset to a value near the maximum U value of the AAP curve.
|TC.GSS - bidirectional power supply|
|C1||Setting controller parameters while using TC.LIN||In general there is a separation of the voltage control (done by TopCon TC.P) and the current (done by TC.LIN).
Thus use the TC.P voltage controller (P, I settings, in rare cases, the current controller P, I),
commonly use the TC.LIN current controller (P,I settings) for controlling the current dynamics.
|D1||Controlling multiple TC.Ethernet interfaces.||Each TC.Ethernet interface is registered at the PC as a COM_x Port. Thus the user can create a TopControl instance for each single TopCon device with direct link to that particular COMport.|
|E1||What are the settings of the serial interface?||Serial Interface on front/rear side is configured to:
38200 Baud, 1Stopbit, no Errorbit, no parity
|E2||Can I work with a USB adapter with SASControl?||
In general it is possible. If problems arise, the so-called "longer comm timeout" settings need to be adapted.
SASControl: Add those two parameters in the SASCore.ini file.
|E3||Accessing multiple TopCon devices from one TopControl instance.||
The connection to more than one TopCon devices is done automatically. TopControl grabs the first open COM interface with a TopCon connected (this port then is closed!)
Another TopControl instance will grab the second open COM interface with a connected TopCon device.
|E4||Accessing a particular COM port.||
Change the command line of the TopControl software to
to search the range from COM7 to COM13.
This allows to assign fixed connections to TopControl icons.
|F1||What is the fastest transition (e.g. voltage step) that can be implemented with SASControl?||Even if the TopCon device can handle steps / transition in much less time and the SASControl software can support that, the shortest transition recommended to be used in SASControl is among 3 seconds. Faster transitions can result in errorneous measurements of the MPP energy counter of the TopCon.|
|F2||When using SASControl with low power curves, the accuracy of the energy counter is bad.||
The TopCon device has a ADC resolution of 12 Bit. Hence, this results in 4000 steps for the full scale values voltage, current, power, ....
When working with SASControl with extremly low power (e.g. 100 W) on a 32 kW TopCon, the minimal resolution is 32000/4000 = 8 W.
>> Using a 10kW TopCon enhances resolution to 2.5W (instead of 8W).
|F3||SASCurve is cut at the upper border.||
The SASCurve is calculated in the TopCon device. To prevent errors, the TopCon device can only create curves that match its own limits.
e.g.: SASControl, connected to a 400 V TopCon cannot create SASCurves with Umpp=700.
|F4||Accessing higher COMPorts||Accessing predefined COM interfaces or COMPorts > 10 requires at least SASCore 0.1.8.7. Please refer to Regatron support if you need that.|
|G1||Problems with .net API when used in LabView (Assembly on remote drive||
(Solution from a NI forum thread )
.NET constructors don't show up in LV 8.5/9/...
|G2||Switch from TFE mode to normal mode (setting U,I,P without TFE)||The TopCon Function Engine (TFE) is a powerful, complex structure that influences the preset values of U,I, P if the related function block is switched on. The whole TFE can be switched on/off by the "General enable" bit.
If the user wants to switch off the TFE, please create one single TFE function with the GeneralEnable bit set to false (checkbox unchecked) and store that curve on the TopCon.
Calling that curve is the same as unchecking the GeneralEnable bit in TopControl.
