UPI RF COM Communication Driver

RF COM is driver to communicate with Reverse Pulse Rectifier of UPI Co.,Ltd in Korea.

1. Read settings

<Figure 1> is read setting example of UPI RF COM communication driver.

<Figure 1> Read setting example of UPI RF COM communication driver

Device part of <Figure 1> input Device type(COM1), Com Baud(19200), Parity Bit(0), Data Bit(8), Stop Bit(1).

Reference) You can change station of UPI RF COM device and Com Baud, etc by using setting button for the front of device. ( Refer to 4 paragraph )

Read schedule example)

1) Station : Station among no.0 ~ no.255.

2) Device Type : S = Read entire data ( Refer to <Table 1> ), X = Read partial data ( Refer to <Table 2> ),

3) Read Start Address : Don't care

4) Save Start Address for Communication Server : Saving start address for Communication Server. ( 0 ~ 9999 )

5) Read Size : Size to read. ( Fixed to 1, refer to <Table 1> and <Table 2> about size and contents for real read data )

Notice) Value which is read by read command of UPI RF COM driver is saved at designated address of WORD, FLOAT, DWORD, STRING together.

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

<Figure 2> Example of UPI RF COM driver's Option dialog box

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

 

<Figure 3> Example of UPI RF COM driver's read schedule Add/Edit dialog box

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

2. Write settigs

You can read/write of data by using digital/analog output command.

Digital Write

Digital write and analog write have the same setting parameters except output value(0,1).

Analog Write

You can output read of data and setting value by using analog output.

Analog write setting parameters are as follows :

1) PORT : Port number which set UPI RF COM communication driver. (0 ~ 255)

2) STATION : Station number among no.0 ~ no.255.

3) Address : Read command of S and X : Memory position to save read value, (Save contents and position refer to <Table 1> and <Table 2>)

Etc : Don't care.

4) Extra1 : Command. (Refer to <Table 3>)

One of S, X, M, R, T1, T2, T3, T4, C1, C2, V1, V2, XC, XV, AO, H0, H1, I and F

5) Extra2 : Don't care,

Write example 1)

Station : 255  Address : 0150  Extra1 : S, EXTRA2 : Blank

If you set as above and output the analog value, it reads and saves entire data of 255 RF COMI device to no.150 addr ~ WORD/DWORD/FLOAT memory such as <Table 1>.

Write example 2)

Station : 255  Address : 0150  Extra1 : X, EXTRA2 : Blank

If you set as above and output the analog value, it reads and saves partial data of 255 RF COMI device to no.150 addr ~ WORD/DWORD/FLOAT memory such as <Table 2>.

Write example 3)

Station : 255  Address : 0000  Extra1 : M, EXTRA2 : Blank

If you set as above and output the analog value, you can change M value(namely mode) of 255 RF COMI device.( 0 = CV mode, 1 = CC mode )

Write example 4)

Station : 255  Address : 0000  Extra1 : R, EXTRA2 : Blank

If you set as above and output the analog value, you can change R value(namely status of run) of 255 RF COMI device.( 0 = Stop, 1 = Run ).

Write example 5)

Station : 255  Address : 0000  Extra1 : T1, EXTRA2 : Blank

If you set as above and output the analog value, you can change T1 value(namely primary Soft Start Time value) of 255 RF COMI device as set value.

Write example 6)

Station : 255  Address : 0000  Extra1 : T4, EXTRA2 : Blank

If you set as above and output the analog value, you can change T4 value(namely secondary current/voltage holding time) of 255 RF COMI device as set value.
