Smart Eye R4 Communication Driver

Smart Eye R4 communication driver is driver to communicate with power monitoring controller of BMT Co,. Ltd. in Korea.

1. Read settings

<Figure 1> is read setting example of Smart Eye R4 communication driver.

<Figure 1> Read setting example of Smart Eye R4 communication driver

 Device part of  <Figure 1> input Com Port(COM8), Baud Rate(38400), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, accordint to the setting of controller.

Read schedule of Smart Eye R4 communication driver

Read schedule setting parameters are as follows:

1)    Station – module ID number of controller, 0 ~ 99.

2)    Read command – command : PHAS, CONS, CALI, QUAL, THD, ID. ( 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, PHAS, 0, 0, 1,
READ, 0, CONS, 2, 1, 1,

<Table 1> is read command and contents of Smart Eye R4 communication driver.

Smart Eye R4 communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE 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 Smart Eye R4 communication driver’s Option dialog box

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

<Figure 3> Example of Smart Eye R4 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 Smart Eye R4 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             module ID number of controller, 0 ~ 99.

3)  ADDRESS          don't care.

4)  Extra1                  write command = ID.

5) Extra2                   don't care.

Write example 1) 

PORT : 0   STATION : 0   ADDRESS : 0000  EXTRA1 : ID  EXTRA2 : 0

The setting parameter shown above is module ID setting(writing value = 0 ~ 99) example for Smart Eye R4 controller.

Block Write

Block write use PlcScanWriteBlock script such as follows.

 CONS Block write command use 'double' script variable, also CALI Block write command 'ushort' script variable.

script function and parameters : @PlcScanWriteBlock(int port, int station, int address, string extra1, string extra2, object array_value, int array_size);

    Block write script example 1 ( CONS block write )

double  Val[9];

Val[0] = 0.1064;
Val[1] = 0.3064;
Val[2] = 0.2064;
Val[3] = 0.1064;
Val[4] = 0.1064;
Val[5] = 0.1064;
Val[6] = 0.1064;
Val[7] = 0.1064;
Val[8] = 0.1064;
@PlcScanWriteBlock(0, 0, 0, "CONS", 0, Val, 9);

    Block write script example 2 ( CALI block write )

ushort  Val[9];

Val[0] = 12286;
Val[1] = 255;
Val[2] = 32767;
Val[3] = 40000;
Val[4] = 65535;
Val[5] = 1026;
Val[6] = 32767;
Val[7] = 32769;
Val[8] = 40000;
@PlcScanWriteBlock(0, 0, 0, "CALI", 0, Val, 9);
