SanRex DC AUTO C Type Communication Driver

SanRex DC AUTO C Type is driver to communicate with controller of 三 社 電 機  製 作 所 Corp., Ltd, in Japan.

1. Read settings

<Figure 1> is read setting example of SanRex DC AUTO C Type communication driver.

<Figure 1> Read setting example of SanRex DC AUTO C Type driver

Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(2), Data Bit(8), Stop Bit(1) respectively, according to device.

Also, you can enter the read delay time after writing(0 ~ 5000 mSec, Default = 500), whether to save communication status by station(0 : Don't care, 1 : Use, Default = 0) and save start address of communication status by station by classifying as comma(,).

Reference) Refer to no.4 item for Device number setting of SanRex DC AUTO C Type.

SanRex DC AUTO C Type driver's read schedule

Read schedule setting parameters are as follows:

1) STATION : STATION number of device. ( 1 ~ 31 )

2) Read Type : Designate data type to read.

SET2 – Reading setting data as in LO HI byte order,

SET – Reading setting data as in HI LO byte order,

DATA2 – Reading monitoring data as in LO HI byte order,

DATA or Etc – Reading monitoring data as in HI LO byte order,

3) Read Start Address : Don't care. (Fixed to 0)

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

5) Read Size : Size to read. (Fixed to 19)

Read schedule example)

READ,    1,   DATA2,   0,   0,   19,

READ,    1,    SET2,   0,  20,   19,

SanRex DC AUTO C Type driver's read value is saved at WORD/DWORD/FLOAT memory as same value(value type is only different).

If you click the icon  in protocol option part at <Figure 1>, you can see the dialog box such as <Figure 2>. You can also set read schedule by using this part.

<Figure 2> SanRex DC AUTO C Type driver's Option dialog box

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

Also, you can set read delay time at 'Write After Delay' area of <Figure 2>, and can set whether to save communication status by STATION at 'Each Station Comm Status Save' area and save start address of communication status by STATION at 'Save Start Pos' area.

<Table 9> is save address and save contents of communication status by STATION, when use Save Communication Status by STATION.

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

2. Writing settings

You can change setting value and etc of device by using writing settings.

Digital/Analog Write

Digital write setting parameters are as follows :

1) PORT           Connected PORT number

2) STATION      STATION number of device. ( 1 ~ 31 )

3) Address      INPUT, SET2 Command : Designate memory save address between no.0 and no.18,

                        Etc : Don't care.

4) Extra1          Write command.

START, STOP, READ2, READ, MEM, SET2, SET, OP_MODE, INPUT, … (Refer to <Table 10>)

5) Extra2          OP_MODE Command : Set bit mask for outputting data setting mode,

Etc : Don't care. 

Write example 1)

Station : 1  Address : 0000  Extra1 : START, EXTRA2 : Blank

If you set as above and write analog/digital value, you can operate SanRex DC AUTO C Type of no.1 STATION.

Write example 2)

Station : 1  Address : 0000  Extra1 : STOP, EXTRA2 : Blank

If you set as above and write analog/digital value, you can stop SanRex DC AUTO C Type of no.1 STATION.

Write example 3)

Station : 1  Address : 0000  Extra1 : MEM, EXTRA2 : Blank

If you set as above and write analog value as 3, you can chage no.3 setting memory of SanRex DC AUTO C Type of no.1 STATION as current memory.

(If you change the memory, setting value(SET read etc) is changed as changed memory value)

Write example 4)

Station : 1  Address : 0005  Extra1 : INPUT, EXTRA2 : Blank

If you set as above and write analog value, you can change output setting value 1(refer to <Table 5>) of SanRex DC AUTO C Type of no.1 STATION as designated value.

Write example 5)

Station : 1  Address : 0006  Extra1 : Blank, EXTRA2 : Blank

If you set as above and write analog value, you can change output setting value 2(refer to <Table 5>) of SanRex DC AUTO C Type of no.1 STATION as designated value.

Write example 6)

Station : 1  Address : 0000  Extra1 : SET, EXTRA2 : Blank

If you set as above and write analog value, you can send the set inside memory value to SanRex DC AUTO C Type of no.1 STATION(output as in HI LO byte order) by using command of READ, INPUT and etc.

Write example 7)

Station : 1  Address : 0005  Extra1 : SET2, EXTRA2 : Blank

If you set as above and write analog value, you can change(output as in LO HI byte order) the output setting value 1(refer to <Table 5>) of SanRex DC AUTO C Type of no.1 STATION as designated value(after reading setting value by using READ2 command).

Write example 8)

Station : 1  Address : 0000  Extra1 : OP_MODE, EXTRA2 : 33888

If you set as above and write analog value, you can output data setting mode of SanRex DC AUTO C Type of no.1 STATION by bit masking.

In case of output as above, because 33888 is 8460h, 8th and 4th bit are always ON, and set the output value of 7th and 6th bit according to ON/OFF status, and setting the rest of bit by reading current set value.

3. Power and communication cable connection

Connection for power and communication cable between SanRex DC AUTO and computer is as follows.

Power connection

Connect 220 V AC to R, S terminal which is the back of SanRex DC AUTO C Type, such as <Figure 4>.
