REFUsol Inverter Communication Driver

REFUsol Inverter is the driver to communicate with 008K - 020K Inverter of REFUsol Elektronik GmbH in Germany.

1. Read settings

<Figure 1> is read setting example of REFUsol Inverter communication driver.

<Figure 1> Read setting example of REFUsol Inverter communication driver

Device part of  <Figure 1> input com port(COM6), baud rate(38400), parity bit(0), data bit(8), stop bit(1)  respectively, accordint to the setting of inverter.

Read schedule of REFUsol Inverter communication driver

Read schedule setting parameters are as follows:

1) station – 0 ~ 31 station ID.

2) read data type – B : byte, W : word, D : double word, F : float  data(IEEE854 format).

3) read start address – 0 ~ 2047 data address.(refer to Chapter 3)

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read size – fixed to 1.

6) sub address – 0 ~ 65535 index number.

READ, 1, D, 92, 4, 1, 1,
READ, 1, D, 92, 5, 1, 2,

REFUsol Inverter communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE, INT64 memory, but the data format are different.

If you click the icon  in protocol option part at <Figure 1>, you can see the dialog box such as <Figure 2>. you can also set read schedule by using this part. 

<Figure 2> Example of REFUsol Inverter communication driver’s Option dialog box

You can set read schedule by using , ,  button and listbox of <Figure 2>.

<Figure 3> Example of REFUsol Inverter communication driver’s read schedule Add/Edit dialog box

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.

2. Write settings

You can read current value by using 'write settings'. 

Digital Write

Digital write and analog write have the same setting parameters except output value. 

Analog Write 

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             0 ~ 31 station ID.

3)  ADDRESS          0 ~ 2047 data address.(refer to Chapter 3)

4)  Extra1                  x.sss type command.

         x =  B : byte, W : word, D : double word, F : float  data(IEEE854 format), VER : read version information.

        sss = sub index number(0 ~ 65535). (default value = 0) 

5)  Extra2                 saving start address of Communication Server.

Write example 1) 

PORT : 0   STATION : 1   ADDRESS : 92  EXTRA1 : D.2   EXTRA2 : 80

The setting parameter shown above is read setting example for 1 inverter ID, 92 data address, 2 index address, data type = double word.

After reading, the readed value save at 80 WORD/DWORD/FLOAT/DOUBLE/INT64 memory of Communication Server.

Write example 2) 

PORT : 0   STATION : 1   ADDRESS : 0  EXTRA1 : VER   EXTRA2 : 90

The setting parameter shown above is 'version' read setting example for 1 inverter ID( 0 data address, 0 index address).

After reading, the readed value save at 90 STRING memory of Communication Server.
