KEN-200DM communication driver

 

KEN-200DM communication driver is the driver to communicate with demand controller of KD Power Co,. Ltd. in Korea.

 

1. Read Settings

 

<Figure 1> is read setting example of KEN-200DM communication driver.

<Figure 1>  Read setting example of KEN-200DM communication driver

Device part of  <Figure 1> input device type(TCP/IP), IP address of controller(192.168.1.194), service port of TCP/IP protocol (500001),respectively, according to setting of controller.

In protocol option part, you can set the following: client type(0 : local, 1 : PC lan, ..., default = 0), controller type( 0 : demand, 1 : power factor, 2 : turbo, default = 0 ), IP address of client( example : 192.168.1.94), password of client(default = 1234). Each argument  is a comma-delimited.

 

Note) IP address of KEN-200DM controller can set by using 'setting button', but service port of TCP/IP fixed to 50001, 50002.

 

KEN-200DM communication driver read schedule 

Read schedule setting parameters are as follows:

1) Station – Don't care.

2) Read command – DEMAND, CURR, SYS, LOAD.

DEMAND : read of Demand data,

CURR : read of voltage, current, power, power factor, ...,

SYS : read of system setting(password, user name, site name),

LOAD : read of load status.

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. ( refer to <Table 1> )

 

Read schedule example)  

READ,     0,    DEMAND,     0,    0,   1,

READ,     0,    CURR,     0,   50,   1,

 

<Table 1> is data saving address and contnets for each read command.

<Table 1> Data saving address and contnets for each read command

KEN-200DM communication driver store the same data in WORD, DWORD, FLOAT, STRING 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-200DM communication driver¡¯s Option dialog box

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

Also, you can set 'client type', 'controller type', 'IP address of client', 'password of client' by using the part of 'Client Type', 'KEN Device', 'Client IP', 'Login Password' of <Figire 2>.

<Figure 3> Example of KEN-200DM 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

KEN-200DM communication driver don't support 'Writing settings'.

 

3. Connection of communication cable

Please connect ethernet cable or RS-232C cable to LAN or serial communication port.
