1. Read settings

<Figure 1> is read setting example of Capricorn 2000 Weather Station communication driver.

<Figure 1>  Read setting example of Capricorn 2000 Weather Station communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively.

Also input continuous reading timeout count( 1 ~ , default = 20 ), then send read request command, by using option part.

Capricorn 2000 Weather Station communication driver’s read schedule 

Read schedule setting parameters are as follows:

1) STATION – Don't care.

2) Read command – Read command = Curr. (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 – Size = Fix to 1. ( Refer to <Table 1> )

Read schedule example)

READ,    1,    Curr,    0,    0,   1,

<Table 1> is a description of store values and contents of 'Curr' read command. 

Capricorn 2000 Weather Station communication driver store the same data in WORD, DWORD, FLOAT, STRING memory, but the data format are different.

Note) Capricorn 2000 controller designed to communicate with periodically data sending from controller.

            Normally wind direction and wind speed communicate by 1 second period, other data can setting to controller.(15 second, 60 second , .... )

             data reading time setting command :  XSET

           data reading time write example)

                           STOP                                           - Stop reading command

                           15 XSET                                       - 15second data reading time setting write example

                           START                                         - Start reading command

  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 Capricorn 2000 Weather Station communication driver’s Option dialogue box

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

<Figure 3> Example of Capricorn 2000 Weather Station communication driver’s read schedule Add/Edit dialogue 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 set Capricorn 2000 Weather Station equipment by using write settings.

Bit Write 

Bit write and word write have the same setting parameters except output value.( 0 or 1 )

Word Write

Word write setting parameters are as follows:

1)  PORT                   port no. (0 ~ 255)

2)  STATION             Don't care.

3)  ADDRESS          Don't care.

4)  Extra1                   Write command.

          START : read start.

          STOP : read stop,

          etc : etc write command.

5)  Extra2                   Don't care.

 Write example 1)

PORT : 0 , STATION : 1,  ADDRESS : 0000,  EXTRA1 : START,  EXTRA2 :

The setting parameter shown above is an example of word write for 'read start' command.

 Write example 2)

PORT : 0 , STATION : 1,  ADDRESS : 0000,  EXTRA1 : STOP,  EXTRA2 :

The setting parameter shown above is an example of word write for 'read stop' command.

3. connection of main power line and communication cable

  Connection of main power line and communication cable are as follows.

Connection of main power line
