Kubota KF-C3000 Weight Meter communication driver

Kubota KF-C3000 Weight Meter communication driver is the driver to communicate with weight meter of Kubota in Japan.

1. Read Settings

<Figure 1> is read setting example of Kubota KF-C3000 Weight Meter communication driver.

<Figure 1>  Read setting example of Kubota KF-C3000 Weight Meter communication driver

Device part of  <Figure 1> input Device Com port( COM6 ), Baud rate( 19200 ), Parity bit( 0 ), Data bit( 8 ), Stop bit( 2 ) respectively, according to setting of meter.

In protocol option part, you can set weather to use KF-C3000 model( 0 : C88 model, 1 : C3000 model, default = 1 ).

Kubota KF-C3000 Weight Meter communication driver read schedule

Read schedule setting parameters are as follows:

1) Station address – 0 ~ 31 station number of meter.

2) Read command – command = ALL, PARA, DATA.

3) Read start address – reading parameter number when PARA, DATA command.

4) Save start address for Communication Server – readed data saving start address of Communication Server.

5) Read Size – fixed to 1.

Read schedule example) 

READ, 1,    ALL,    0,  0,  1,

READ, 1,    PARA, 117, 15,  1,
 

<Table 1> is data saving address and contents for ALL read command.

Kubota KF-C3000 Weight Meter communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE memory, but the data formats 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 Kubota KF-C3000 Weight Meter communication driver’s Option dialogue box

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

Also, you can set weather to use KF-C3000 model by using 'Meter is KF-C3000 Model' part of <Figire 2>.

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

2. Write settings

You can set parameter value and etc by using write 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                   port no. (0 ~ 255)

2) STATION              0 ~ 31 station number of meter.

3) ADDRESS           0 ~ 999 parameter number when PARA write command.

4) EXTRA1            Write command = PARA, S, R, Q, B, C, U, L, V, M, K, N.

PARA : parameter value setting command, 

S : flow setting command,

R : ratio setting command,

Q : fixed quantity setting command,

B : pre-fixed quantity setting command,

C : weight compensation value setting command,

U : high limit of weight setting command,

L : low limit of weight setting command,

V : high-high limit of weight setting command,

M : low-low limit of weight setting command,

K : moisture content ratio setting command, 

N : motor speed ratio setting command.

5) Extra2          0 ~ 5 decimal unit for writing value.

Write example 1)

PORT:0,  station:1, ADDRESS:0183, Extra1:PARA,  Extra2 : 2

The setting parameter shown above is compensation value setting example with 2 decimal unit value.

Write example 2)

PORT:0,  station:1, ADDRESS:0117, Extra1:PARA,  Extra2 : 3

The setting parameter shown above is flow value setting example with 3 decimal unit value.

Write example 3)

PORT:0,  station:1, ADDRESS:0117, Extra1:U,  Extra2 : 2

The setting parameter shown above is high limit of weight setting example with 2 decimal unit value.

Write example 4)

PORT:0,  station:1, ADDRESS:0117, Extra1:L,  Extra2 : 2

The setting parameter shown above is low limit of weight setting example with 2 decimal unit value.
