K-Water communication driver

K-Water communication driver is the driver to communicate with water level monitoring controller.

1. Read Settings

<Figure 1> is read setting example of K-Water communication driver.

<Figure 1>  Read setting example of K-Water 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.

In protocol option part, you can set the following: analog input tag for read of saved(old) data, equipment type( 0 : water level, 1 : rainfall controller, default = 0 ). Each argument  is a comma-delimited.

Input example) AI_0000, 0,

= analog input tag for read of saved data : AI_0000, equipment type : water level controller.

K-Water communication driver read schedule 

Read schedule setting parameters are as follows:

1) Year – Year value when DATA read command.

2) Read command – Read command. ( refer to <Table 1> )

TSYN - time syncronization ( syncronize with computer time )

RST  - reset of equipment.

TIME - current time read of controller (year, month, day, hour, minute, second)

STS - status request (status 4 ~ 1)

DATA - read of saved(old) data(10 byte data) 

LOG - read of Log data (year, month, day, hour, minute, status)

CURR or etc - read of current water level (current water level : 0 ~ 65535)

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> )

6) Extra2 – Month, Day when DATA read command, High 2digit = month, Low 2 digit = day.

7) Extra3 – Hour, Minute when DATA read command, High 2digit = hour, Low 2 digit = minute.

Read schedule example) 

READ,   0,     CURR,    0,    0,   1,

READ,   0,     TIME,    0,    5,   6,

READ,   0,      STS,    0,   15,   4,

<Table 1> is read command and contents of K-Water communication driver. 

If you click the icon  in protocol option part at <Figure 1>, you can see the help dialogue box such as <Figure 2>.

You can set 'analog input tag, equipment type and etc' at <Figure 2>.

2. Writing settings

You can set K-Water controller by using 'writing settings'. 

Digital Write 

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             Year value when DATA read command( other command = don't care).

3)  ADDRESS          Read data saving address when TIME, STS, DATA, LOG, CURR write command( other command = don't care).

4)  Extra1                   Write command = TSYN, RST, TIME, STS, DATA, LOG, CURR or space. ( refer to <Table 2> )

5) Extra2                   Month( high 2 digit ), day ( low 2 digit ) when DATA read command( other command = don't care).

Write example 1)

PORT:0,  station:0, ADDRESS:0000, Extra1: TSYN,  Extra2 : 0

The setting parameter shown above is time syncronization setting example.

Write example 2)

PORT:0,  station:0, ADDRESS:0015, Extra1: TIME,  Extra2 : 0

The setting parameter shown above is current time read of controller example.

After reading, the readed data save at 15 ~ 20 WORD memory. ( 15 = year, 16 = month, 17 = day, 18 = hour, 19 = minute, 20 = second )

Write example 3)

PORT:0,  station:0, ADDRESS:0010, Extra1: CURR,  Extra2 : 0

The setting parameter shown above is current water level read example.

After reading, the readed data save at 10 WORD memory.

<Table 2> is write command and contents of K-Water communication driver. 

Analog Write

Analog write and digital write have the same setting parameters except output value. 

Note) Reading data time of DATA write command input 'STATION =  year, EXTRA2 = high 2digit - month, low 2 digit - day, Output value = high 2 digit - hour, low 2 digit - minute'.

Write example 1)

PORT:0,  station:2013, ADDRESS:0500, Extra1: DATA,  Extra2 : 0508, Output value = 1630

The setting parameter shown above is saved data reading example that the reading time is 2013-05-08 16:30.

After reading, the readed data save at 500 ~ 509(10 saved data ) WORD memory.
