YAMATAKE DCP Series is driver to communicate with DCP Series(550 etc) controller of Yamatake-Honeywell Co. in Japan.

1. Read settings

<Figure 1> is read setting example of YAMATAKE DCP Series(550 etc) protocol.

<Figure 1> Read setting example of YAMATAKE DCP Series protocol

 

Device Setting of <Figure 1> are input, Com Port(COM1), Com Baud(9600), Parity Bit(2), Data Bit(8), Stop Bit(1).

Read schedule example)

1) Station : Station number which set at controller.

              Station - 0 ~ 255 (Low byte), sub Station – High byte.

2) Data Type : Data type to read.

DATA - Read state value of general controller.

R_FILE – Read FILE data.

3) Read Start Address : Memory start address to read.

DATA – Memory start address to read. (Refer to <Table 1> or communication parameter table manual of controller)

R_FILE – FILE number to read.

4) Save Start Address for Communication Server : Saving start address of Communication Server.

5) Read Size : The number of items to read at a time or segment number of FILE.

DATA – The number of items to read,

R_FILE – Segment number of FILE.

If you click the icon  in protocol option part, you can see the dialog box such as <Figure 2>. you can also set read schedule by using this part.

2. Write settings

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

Digital Write

You can set or control DCP Series controller by using the digital write command.

Digital write setting parameters are as follows :

1) PORT : Connected PORT no.(0 ~ 255)

2) Station : Station number which set at controller.

           Station - 0 ~ 255 (Low byte), sub Station – High byte.

3) ADDRESS : Memory address to output, Save address for read FILE data, Order number of file name. (Decimal)

DATA, RUN, SET – Memory WORD address to output. Possible to write at printable area only. (Refer to <Table 1> or communication parameter table manual of controller)

R_FILE – WORD memory start address to save the read FILE data.

R_FILE2 – Order number of file name to save the read FILE data.

File name is saved at 'ProjectFolder\SCAN\file%04d.txt', and in this path %04 is order number of file name.

Ex) If setting is 'Extra1 : R_FILE2, ADDRESS : 0000', file name is ProjectFolder\SCAN\file0000.txt.

W_FILE – Order number to read when FILE data is output.

File name is saved at 'ProjectFolder\SCAN\file%04d.txt', and in this path %04 is order number of file name.

Ex) If setting is 'Extra1 : W_FILE, ADDRESS : 0001', file name is ProjectFolder\SCAN\file0001.txt.

4) Extra1 : Output area.

DATA – Output general memory data. (Read and calculate the previous data)

RUN – Output the Run Operation Bit.

SET – Output the general memory address data. (Output only the designated digital bit value)

R_FILE – Read FILE data and save to designated WORD memory.

R_FILE2 – Read FILE data and save to designated file('ProjectFolder\SCAN\file%04d.txt').

W_FILE – Read FILE data at designated file('ProjectFolder\SCAN\file%04d.txt'), and output the FILE contents.

5) Extra2 : Bit position or Program number.

DATA, RUN – Bit position number(no.0 ~ no.15).

R_FILE, R_FILE2, W_FILE – Program number.      Notice) Segment number is output value.

Ex 1) Port : 0, Station : 1, Address : 0301, Extra1 : DATA, Extra2 : 1

The setting parameter shown above is example of writing setting.

You can change(ON/OFF) the 2nd bit value of address no.301 of DCP Series controller.

Ex 2) Port : 0, Station : 1, Address : 0100, Extra1 : R_FILE, Extra2 : 1

The setting parameter shown above is example of writing setting.

If you output ON digital(no.1 Segment), it read no.1 Program ID of DCP Series controller and no.1 Segment FILE contents and save these read contents to WORD memory from address no.100.

Analog Write

You can set or control DCP Series controller by using the analog write command.

Analog write setting parameters are as follows :

1) PORT : Connected PORT no.(0 ~ 255)

2) Station : Station number which set at controller.

           Station - 0 ~ 255 (Low byte), sub Station – High byte.

3) ADDRESS : Memory address to output, Save address for read FILE data, Order number of file name. (Decimal)

DATA – Memory WORD address to output. Possible to write at printable area only. (Refer to <Table 1> or communication parameter table manual of controller)

R_FILE – WORD memory start address to save the read FILE data.

R_FILE2 – Order number of file name to save the read FILE data.

File name is saved at 'ProjectFolder\SCAN\file%04d.txt', and in this path %04 is order number of file name.

Ex) If setting is 'Extra1 : R_FILE2, ADDRESS : 0000', file name is ProjectFolder\SCAN\file0000.txt.

W_FILE – Order number to read when FILE data is output.

File name is saved at 'ProjectFolder\SCAN\file%04d.txt', and in this path %04 is order number of file name.

Ex) If setting is 'Extra1 : W_FILE, ADDRESS : 0001', file name is ProjectFolder\SCAN\file0001.txt.

4) Extra1 : Output area.

DATA – Output general memory data.

R_FILE – Read FILE data and save to designated WORD memory.

R_FILE2 – Read FILE data and save to designated file('ProjectFolder\SCAN\file%04d.txt').

W_FILE – Read FILE data at designated file('ProjectFolder\SCAN\file%04d.txt'), and output the FILE contents.

5) Extra2 : Program number.

DATA – Don't care.

R_FILE, R_FILE2, W_FILE – Program number.      Notice) Segment number is output value.

Ex 1) Port : 0, Station : 1, Address : 0302, Extra1 : DATA, Extra2 : Blank

The setting parameter shown above is example of writing setting.

After writing as analog, you can change CH1 Temperature Unit (address no.302) of DCP Series controller.

Ex 2) Port : 0, Station : 1, Address : 0200, Extra1 : R_FILE, Extra2 : 1

The setting parameter shown above is example of writing setting.

If you output analog value(no.1 Segment) as 1, it read no.1 Program ID of DCP Series controller and no.1 Segment FILE contents and save these read contents to WORD memory from address no.200.

Ex 3) Port:0, Station:1, Address:0001, Extra1:R_FILE2, Extra2:1

The setting parameter shown above is example of writing setting.

If you output analog value(no.1 Segment) as 1, it read no.1 Program ID of DCP Series controller and no.1 Segment FILE contents and save these read FILE contents to 'ProjectFolder\SCAN\file0001.txt'.

Ex 4) Port:0, Station:1, Address:0001, Extra1:R_FILE2, Extra2:1

The setting parameter shown above is example of writing setting.

If you output analog value(no.1 Segment) as 1, it read no.1 Program ID of DCP Series controller and no.1 Segment FILE contents and save these read FILE contents to 'ProjectFolder\SCAN\file0001.txt'.
