YOKOGAWA YS Series communication driver

YOKOGAWA YS Series(150 etc) communication driver is the driver to communicate with YS series Multi Function controller of Yokogawa M&C in Japan.

1. Read settings

<Figure 1> is read setting example of YOKOGAWA YS Series communication driver.

<Figure 1> Read setting example of YOKOGAWA YS Series communication driver

Device part of <Figure 1> input Device type(COM1), Com Baud(1200), Parity Bit(0), Data Bit(8), Stop Bit(1).

Device settings of YOKOGAWA YS Series are changed according to Multi Function controller settings.

Com Baud, Parity, Data and Stop Bit of YOKOGAWA YS Series can be changed by operation control of Multi Function(function of PID, etc) controller.

Read schedule example

1) Station : Station number of YOKOGAWA YS Series Multi Function controller. (1 ~ 16)

2) Data Type : Data type to read such as PV1, PV2, SV1, SV2, etc.

                 The number of 1 ~ 7 data can be input together by classifying as blank(space). (Ex : PV1 PV2 SV1 SV2 )

3) Read start address : Don't care (Input always 0)

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

5) Read size : Read size. (Fixed to 1, it is set automatically according to read contents of data type to read (among the number of 1 ~ 7)

Note) Save the read value from all memory of WORD, DWORD, FLOAT, in case of setting as READ, DWORD, FLOAT, etc. (Part of read/write command is different)

Also, CNT1, CNT2 read command save the read value from WORD, DWORD, FLOAT, STRING memory by classifying.

In case of uncommon read/write data)

LS1, LS2  :  MAN = 0, AUT = 1, CAS = 2, SPC = 3, DDC = 4, BUM = 5, BUA = 5.

PRCA, SYSA, SLS1, SLS2 : no. 0 ~ 7 bit state value (Refer to YS Series manual)

STCA : no. 0 ~ 15 bit state value. (Refer to YS Series manual)

ASW1 ~ ASW6 : no.0 ~ 7 bit state value. (Refer to YS Series manual : Only YS131, YS135, YS136 model)

CNT1, CNT2 : Read six state value and two string, and save that contents to address(no.+ 0 ~ 7) which is save position of read contents.

                Save position no.0 ~ 5  : Control Type, Control Computation, Action Direction, Open Valve Direction, C Mode, Backup Mode,

                Save position no.6 ~ 7 (only String memory) : Unit (Maximum 6 digit string), Tag Number (Maximum 12 digit string).

SYS1 : Read three state value, and save that contents to save address(no.+ 0 ~ 2).

                Save position no.0 ~ 2 : Control Mode, Recovery from Power Failure, Settable by Communications.

SYS2 : Read six state value, and save that contents to save address(no.+ 0 ~ 5).

                Save position no.0 ~ 5 : PF key, DI1 Function, DI1 Set Active, Alarm Output Contact Status, SV Tracking, Selector.

ID : Save the ID string to String memory.

Read data type and contents of YS150, YS170 models are the following <Table 1-1> ~ <Table 1-3>, and YS131, YS135, YS136 models are the following <Table 2-1> ~ <Table 2-2>.

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.

<Figure 2> Example of YOKOGAWA YS Series protocol option dialog box

   

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

<Figure 3> Example of YOKOGAWA YS Series's read schedule Add/Edit dialog box

When you click Add button or Edit button in dialog box of <Figure 2>, dialog box of <Figure 3> is shown.

2. Writing settings

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

Digital Write

Digital write and analog write have the same setting parameters except output value(0, 1).

Analog Write

Analog write send WORD data value to controller.

You can set SV1, SV2, MV1, MV2 value, etc of Multi Function controller by using the analog writing.

Analog write setting parameters are as follows :

1) PORT         Connected Port number.

2) STATION      Station number of Multi Function controller. (1 ~ 16).

3) Address       In case of Extra2 is 0 : Not use.

                  In case of Extra2 is number except 1 : Start address to save the read contents as Extra1 command.

4) Extra1         In case of Extra2 is 0 : Data type to output such as SV1, SV2, MV1, MV2 etc. (Output one data at a time)

                  In case of Extra2 is number except 1 : Data type to output. (The number of 1 ~ 7 data can be input together by classifying as blank(space)).

5) Extra2         0 : Write output.

                  Except 1 : Read command. (Save read data from Address first)

Write example 1)

PORT : 0   STATION : 1   ADDRESS : 0020  EXTRA1 : PV1 PV2 SV1 SV2 MV1 MV2   EXTRA2 : 1

The setting parameter shown above is example of writing setting.

If you output as digital/analog, it reads PV1, PV2, SV1, SV2, MV1, MV2 value of YS Series equipment and save the read data at WORD, DWORD, FLOAT, STRING Communication Server buffer of address no.20 ~ 25.

Write example 2)

PORT : 0   STATION : 1   ADDRESS : 0055  EXTRA1 : PRCA SYSA   EXTRA2 : 1

The setting parameter shown above is example of writing setting.

If you output as digital/analog, it reads PRCA (Process Alarm), SYSA (System Alarm) state of YS Series equipment and save the read data at WORD, DWORD, FLOAT Communication Server buffer of address no.55 (PRCA), 56 (SYSA).

Write example 3)

PORT : 0   STATION : 1   ADDRESS : 0120  EXTRA1 : CNT1 CNT2   EXTRA2 : 1

The setting parameter shown above is example of writing setting.

If you output as digital/analog, it reads CNT1, CNT2(Control Model Set Information1, 2) value of YS Series equipment and save the read data at WORD, DWORD, FLOAT, STRING(Last 2 address : Unit string, Tag string) Communication Server buffer of address no.120 ~127(CNT1), 128~135(CNT2).

Write example 4)

PORT : 0   STATION : 1   ADDRESS : 0000  EXTRA1 : SV1   EXTRA2 : 0

The setting parameter shown above is example of writing setting.

If you writing as analog, SV1 of YS Series equipment is changed as set value(-6.3 ~ 106.3).

Write example 5)

PORT : 0   STATION : 1   ADDRESS : 0000  EXTRA1 : PB1   EXTRA2 : 0

The setting parameter shown above is example of writing setting.

If you writing as analog, PB1(Proportional band) of YS Series equipment is changed as set value(2.0 ~ 999.9).

Write example 6)

PORT : 0   STATION : 1   ADDRESS : 0000  EXTRA1 : DTC   EXTRA2 : 0

The setting parameter shown above is example of writing setting. 

If you writing as analog, DTC(Watch Dog Timer) of YS Series equipment is changed as set value(0 ~ 9999).

Reference) If you use DTC such as 'Write example 6), You can check whether to exist of system of between YS Series(because, computer have to output DTC, periodically).
