1. Read settings

 

<Figure 1> is read setting example of DX100~230 series record communication driver.

<Figure 1> Read setting example of DX100~230 series record communication driver

Device part of <Figure 1> input Device type(TCP/IP), IP address(162.0.9.23), Service port(34260).

Device settings of YOKOGAWA DX 100 ~230 series record are changed according to record settings.

 

Importance) If you want to communicate as TCP/IP type, service port has to be set as 34260. And, you can set whether to display point representation(0 ~ 3) and date/time at protocol option part(0 : Not Display, 1 : Display). (If you leaving as blank, it is set as 1 decimal place and not display the date/time)

 

Read schedule example

Memory Station
(Don't care)
Data Type(Fixed) Read start address Save start address Read size
FLOAT, 0, FD, 1, 0, 20,

1) Station : Don't care.

2) Data Type :  Data type to read. Fixed to FD.

3) Read start address : Memory address to start to read. 1 ~.

4) Save start address for Communication Server : Buf position to save the read state value.

5) Read Size : Number of items to read at a time. Read size is different according to record model.

 

The order of saving the contents, which is read by FD read command, to communication memory is such as <Table 2>.

2. Write settings

Write to direct address of controller, regardless of SCAN File.

 

You can set state value of DX series record by using the digital/analog write command.

Digital/Analog write setting method.

Digital/Analog write setting parameters are as follows :

1) PORT        Connected Port number.(0 ~ 255)

2) Station      Don't care.

3) ADDRESS    Don't care.

4) Extra1       Setting command. Refer to DX100 ~ 230 communication description.

5) Extra2       Don't care.

Ex) Port : 0, Station : Blank, Address : 0000, Extra1 : PS 0, Extra2 : Blank

You can start(PS 1  : Stop) survey of DX series record, when you output digital/analog.
