Notice) Read value of SEE YOUNG POARD communication driver is saved to WORD/DWORD/FLOAT memory(Format of saved value is difference) of set communication memory save address together.

<Table 1> is contents by read type and save position of read value for SEE YOUNG POARD communication driver.

Read Type	Contents	Save address of Read value
0	Error or not, DI status, Reading number of TRIP	Save Addr + 0 ~ 1 : DI status (1 = On, 0 = Off) Save Addr + 2 : Null Save Addr + 3 : Error or not (1 = Be, 0 = None) Save Addr + 4 ~ 5 : Calibration Lock (1 = Lock, 0 = Unlock) Save Addr + 6 ~ 7 : Null Save Addr + 8 : Number of Trip
2	Reading Vr, Ir	Save Addr + 0 : Vr value Save Addr + 1 : Ir value
3	Reading Vs, Is	Save Addr + 0 : Vs value Save Addr + 1 : Is value
4	Reading Vt, It	Save Addr + 0 : Vt value Save Addr + 1 : It value
5	Reading Null, Iz	Save Addr + 0 : Null Save Addr + 1 : Iz value
6	Reading power value	Save Addr + 0 : Power value Save Addr + 1 : Null
7	Reading wattage value	Save Addr + 0 : Wattage value Save Addr + 1 : Null
8	Reading PF, FREQ	Save Addr + 0 : PF Save Addr + 1 : FREQ
A or 10	Time to Read	Save Addr + 0 : Year Save Addr + 1 : Month Save Addr + 2 : Day Save Addr + 3 : Hour Save Addr + 4 : Minute Save Addr + 5 : Second

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 SEE YOUNG POARD communication driver's Option dialog box

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

<Figure 3> Example of SEE YOUNG POARD communication driver's 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. Writings settings

You can set time of device, etc by using writing settings.

Digital Write

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

Analog Write

Analog write setting parameters are as follows :

1) Port Connected communication port number. (Not COM number)

2) Station Device number between 0 and 64.

3) Address Year/Month or error number according to writing type.(Decimal)

TIME : Upper 2 digits = Year, Sub 2 digits = Month, (Example : 0507 = July 07)

CONT, REMO, LOCA : Don't care

Blank, E, etc : Error number between 0 and 30.

4) Extra1 Writing Type.

TIME : Set the current time of device,

CONT : Main breaker control command, (Control value 1 = ON, 0 = OFF )

REMO, LOCA : Remote/Local control command, (Control value 1 = REMOTE, 0 = LOCAL )

Blank, E etc : Reading error data

5) Extra2 Day/Hour or error data save address according to writing type.(Decimal)

TIME : Upper 2 digits = Day, Sub 2 digits = Hour (Example : 2915 = 29 Day 15 Hour)

CONT, REMO, LOCA : Don't care

Blank, E, etc : STRING memory address where read error contents are to be saved.

Notice) Error data read by the error value at writing settings is saved at STRING memory of designated Extra2 address.

Also, when writing type is TIME, output value when writing is Upper 2 digits = Min, Sub 2 digits = Sec. (Example : 2530 = 25min 30sec)

Write example 1)

PORT : 0 STATION : 1 ADDRESS : 0507 EXTRA1 : TIME EXTRA2 : 2915

If you set as above and writing 3145 value, it set current time of SEE YOUNG POARD no.1 device connected with no.0 port as July 29th 2005, 15:31:45.

Write example 2)

PORT : 0 STATION : 1 ADDRESS : 0003 EXTRA1 : Blank EXTRA2 : 5

If you set as above and writing analog value, it saves no.3 error data, by reading from SEE YOUNG POARD no.1 device connected no.0 port, to STRING memory no.5 address.

Write example 3)

PORT : 0 STATION : 1 ADDRESS : 0007 EXTRA1 : Blank EXTRA2 : 15

If you set as above and writing analog value, it saves no.7 error data by reading from SEE YOUNG POARD no.1 device connected no.0 port, to STRING memory no.15 address.

3. Communication cable and power connection
