ODA DC-Power Supply OPM 101E communication driver

ODA DC-Power Supply OPM 101E communication driver is the driver to communicate with DC Power Supply of ODA Technologies in Korea.

1. Read Settings

<Figure 1> is read setting example of ODA DC-Power Supply OPM 101E communication driver.

<Figure 1>  Read setting example of ODA DC-Power Supply OPM 101E communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(115200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.

In protocol option part, you can set whether to check response code when write( 0 = don't check, 1 = check, default = 0). Each argument  is a comma-delimited.

ODA DC-Power Supply OPM 101E communication driver read schedule

Read schedule setting parameters are as follows:

1) Station – 0 ~ 254 station number.

2) Read command – command = B, C, E, F, G, H, I, J, M, N, O, P, T, U, X, Y, a, 9, 0, !, @, ... ( refer to <Table 1> )

3) Read start address – don't care.

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

5) Read size – fixed to 1.

Read schedule example)

READ,     0,     B,     0,    0,   1,

READ,     0,     a,     0,    5,   1,

<Table 1> is read command and contents of ODA DC-Power Supply OPM 101E communication driver.

ODA DC-Power Supply OPM 101E communication driver store the same data in WORD, DWORD, FLOAT, STRING 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 ODA DC-Power Supply OPM 101E communication driver’s Option dialog box

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

Also, you can set whether to check response code when write by using the part of ‘Exist Write Return Code’ shown in <Figure 2>.

<Figure 3> Example of ODA DC-Power Supply OPM 101E 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 set ODA DC-Power Supply OPM 101E controller 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 ~ 254 station number.

3)  ADDRESS          data saving start address when 2, 4, 6, 8 write command.

4)  Extra1                  writte command = C, G, H, k, L, O, P, Q, R, S, Y, W, 1 ~ 8, #, $, %, ^, &, *, (. ( refer to <Table 2> )

refer to <Table 1> and user's manual of  ODA DC-Power Supply for more read/write command.

5) Extra2                   don't care.

<Table 2> is write command and contents of ODA DC-Power Supply OPM 101E communication driver.

Write example 1)

PORT:0,  station:0, ADDRESS:0000, Extra1:G,  Extra2 : 0

The setting parameter shown above is OVP ON/OFF control example.

Write example 2)

PORT:0,  station:0, ADDRESS:0100, Extra1:2,  Extra2 : 0

The setting parameter shown above is Calibration Low voltage setting example.

After writing, save Calibration ADC valut at 100 WORD, DWORD, FLOAT memory.

Note) Protocol of ODA DC-Power Supply OPM 101E don't use response code after writing.( except 2, 4, 6 9 write command )

Therefore, you should check writing data by read Procedures.

3. Connection of communication cable and main power

Connection of communication cable and main power are as follows:

Connection of communication cable

Please connect normal RS-485 communication cable to D+, D- connector of ODA DC-Power Supply OPM 101E controller such as <Figure 4>.
