1. Read settings

<Figure 1> is read setting example of SEE YOUNG POARD communication driver.

<Figure 1> Read setting example of SEE YOUNG POARD driver

 Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to device.

SEE YOUNG device's Baud Rate, Parity Bit, Data Bit and Stop Bit are fixed to 9600, 0, 8, 1, and device number can be selected between 0 and 64. (Refer to no.4 item)

SEE YOUNG POARD driver's read schedule

Read schedule setting parameters are as follows :

1) Device Number – Device number which was set between 0 and 64.

2) Read Type – Type of value to read. (Refer to <Table 1>)

0 : Error or not, DI status, Reading number of TRIP,

2 : Reading Vr, Ir value,

3 : Reading Vs, Is value,

4 : Reading Vt, It value,

5 : Reading Null, Iz value,

6 : Reading power( W ) value,

7 : Reading wattage( WH ) value,

8 : Reading PF, FREQ value,

A or 10 : Reading current time of device,

Blank, etc : Error or not, DI status, Reading number of TRIP

3) Read Start Address – Don't care

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

5) Read Size – Fixed according to read type.(Always set as 1)

Read schedule example)

READ,     1,     0,     0,    0,   1,

READ,     1,     2,     0,   10,   1,

READ,     1,     3,     0,   12,   1,

READ,     1,     4,     0,   14,   1,

READ,     1,     5,     0,   16,   1,

READ,     1,     6,     0,   18,   1,

READ,     1,     7,     0,   20,   1,

READ,     1,     8,     0,   22,   1,

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.

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

Communication cable connection
