KEN-2000N Power Meter communication driver

KEN-2000N Power Meter communication driver is the driver to communicate with power meter controller of KD Power Co,. Ltd. in Korea.

1. Read Settings

<Figure 1> is read setting example of KEN-2000N Power Meter communication driver.

<Figure 1>  Read setting example of KEN-2000N Power Meter 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 controller.

Note) Baud rate, parity bit, data bit stop bit of KEN-2000N controller are fixed to 9600, 0, 8, 1.

KEN-2000N Power Meter communication driver read schedule 

Read schedule setting parameters are as follows:

1) Station – 0 ~ 255 station number of KEN-2000N Power Meter.

2) Read command – CURR, SET. ( refer <Table 1> ~ <Table 4> )

CURR : read of measurement value,

SET : read of setting value.

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. (  CURR = 110,  SET = 9 )

6) Controller type –  1 = MCC 2060,  2 = AA382I,  0,... = KEN 2000N.

Read schedule example)  

READ,     2,    CURR,     0,     0,   1,   0,

READ,     2,        SET,     0,  120,   1,   0,

Note) refer to setting of MCC 2060 controller

<Table 1>, <Table 2> are data saving address and contnets of CURR read command. ( <Table 2> = for KEN-AA382I Power Meter )

<Table 3> is unit value and contents for KEN-2000N/AA382I Power Meter.

 <Table 4> is data saving address and contnets of SET read command.

Please refer to 'Manual of KEN-2000N Power Meter Controller' for more information.

KEN-2000N Power Meter 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 at <Figure 1>, you can see the dialogue box such as <Figure 2>. you can also set read schedule by using this part. 

<Figure 2> Example of KEN-2000N Power Meter communication driver’s Option dialog box

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

<Figure 3> Example of KEN-2000N Power Meter 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. Writing settings

You can control KEN-2000N controller by using 'writing 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             0 ~ 255 station number of KEN-2000N Power Meter.

3)  ADDRESS          SET, COMMON command – writing address(0 ~ 99, refer to <Table 5>), TIME command - Don't care.

4)  Extra1                  Write command

SET – data setting command,

COMMON - output of common setting,

TIME - time syncronization with computer.

5) Extra2                   Controller type. 1 - MCC 2060, 2 - AA382I, 0 - KEN-2000N.

<Table 5> is address and contents for SET write command.

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1: SET,  Extra2 : 0

The setting parameter shown above is a setting example of P.F-L value(50 ~ 99).

Write example 2)

PORT:0,  station:1, ADDRESS:0099, Extra1: SET,  Extra2 : 0

The setting parameter shown above is SUB WH reset example of 1 station number KEN-2000N Power Meter.

Write example 3)

PORT:0,  station:1, ADDRESS:0000, Extra1: TIME,  Extra2 : 0

The setting parameter shown above is time syncronization with computer example of 1 station number KEN-2000N Power Meter.

3. Connection of communication cable

Please connect A2(+), B2(-) connector(RS-485) of KEN-2000N and Tx+(Rx+), T-(Rx-) of computer such as <Figure 4>.

<Figure 4>, <Figure 5> are connection example of communication cable and main power to KEN-2000N and KD-AA382I Power Meter.
