OVAL BC2000 Communication Driver

OVAL BC2000 Communication Driver is the driver to communicate with Batch Controller of OVAL in Japan.

1. Read settings

<Figure 1> is read setting example of  OVAL BC2000 communication driver. 

<Figure 1>  Read setting example of  OVAL BC2000 communication 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 setting of controller.

Also, you can set 'wait time after ID selection'( 0 ~ 2000 m Sec, default = 50 ) by using option part.

OVAL BC2000 communication driver’s read schedule 

Read schedule setting parameters are as follows:

1) Station – Controller station number = 0 ~ 99.

2) Read Command – Command = BS, T?, R?,C?,O? ( 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,     99,    BS,     0,     0,   1,

FLOAT,    99,    T?,     0,     5,   1,

FLOAT,    99,    R?,     0,   10,   1,

<Table 1> is read command and contents of OVAL BC2000 communication driver. 

OVAL BC2000 communication driver store the same data in WORD, DWORD, FLOAT memory, but the data format are different.

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

<Figure 2> Example of OVAL BC2000 communication driver’s Option dialogue box

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

Wait time after ID selection( 0 ~ 2000 m Sec, default = 50 ) can set by using the part of ‘Wait Time After ID Selection’ shown in <Figure 2>

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

2. Writing settings

You can write the setting value by using write settings.

Digital Write

Digital write setting parameters are as follows:

1)  PORT                    Port no. (0 ~ 255)

2)  STATION               Controller station number = 0 ~ 99.

3)  ADDRESS              Saving start address of Communication Server (Decimal address)

4)  Extra1                   Write command BH, BR, BC ( Refer to <Table 2> )

                                 BH : stop,                          value = Don't care.

                                 BR : reset,                          value = Don't care.

                                 BC : start,                          value = Don't care.

5)  Extra2                   Don't care.

Write example 1) 

PORT : 12 , STATION : 99,  ADDRESS : 0000,  EXTRA1 : BH,  EXTRA2 :

The setting parameter shown above is an example of  stop the OVAL BC2000 device (ID 99) connected to port 12.

Write example 2) 

PORT : 12 , STATION : 99,  ADDRESS : 0000,  EXTRA1 : BR,  EXTRA2 :

The setting parameter shown above is an example of  reset the OVAL BC2000 device (ID 99) connected to port 12.

Write example 3) 

PORT : 12 , STATION : 99,  ADDRESS : 0000,  EXTRA1 : BC,  EXTRA2 :

The setting parameter shown above is an example of  start  the OVAL BC2000 device (ID 99) connected to port 12.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                    Port no. (0 ~ 255)

2)  STATION               Controller station number = 0 ~ 99.

3)  ADDRESS              Saving start address of Communication Server (Decimal address)

4)  Extra1                   Write command BV,BH,BR,BC ( Refer to <Table 2> )

                                 BV : setting batch value,      value = Enter up to 8 digits including integers and decimal places. (Decimal places is discarded, eg 0.12345 → 0.12 for 2 decimal places).

                                 BH : stop,                          value = Don't care.

                                 BR : reset,                          value = Don't care.

                                 BC : start,                          value = Don't care.

5)  Extra2                   Don't care.

6)  Value                    Batch value

Write example 1) 

PORT : 12 , STATION : 99,  ADDRESS : 0000,  EXTRA1 : BC,  EXTRA2 : , VALUE : 11.1

The setting parameter shown above is an example of  Set the batch value of the OVAL BC2000 device (ID 99) connected to port 12 to 11.1.

write Command	Contents
BV	Batch
BH	Stop
BR	Reset
BC	Start
