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 S-TURBO Compressor driver's Option dialog box

You can set read schedule by using , , button and listbox of <Figure 3>.

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 read/write the data by using digital/analog output command.

Digital Write

You can read the data or control as bit unit by using digital write.

Digital write setting parameters are as follows:

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

2) STATION Device's STATION number( 0 ~ 15 ).

3) Address Address to set. (Use, in case of A output command)

4) Extra1 Output command.

A : Send setting value, ( Use analog output, Digital output writes 0 or 1 value)

U : Auxiliary PUMP ON,

W : Compressor Operation ON,

Y : Forcing No-Load,

Z : Forcing Load,

E : Emergency Shutdown ON,

G : Alarm Check,

H : Alarm Clear,

R, S : Run/Set Data read command

5) Extra2 R, S Output Command : Memory start address to save read value, Etc Output Command : Don't care

Write example 1)

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

If you set as above and write digital value, you can ON aux PUMP of no.1 S-TURBO Compressor device. (Both ON/OFF commands do motion of aux PUMP ON)

Write example 2)

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

If you set as above and write digital value, you can ON scram of no.1 S-TURBO Compressor device. (Both ON/OFF commands do motion of scram ON)

Write example 3)

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

If you set as above and write digital value, you can clear alarm of no.1 S-TURBO Compressor device. (Both ON/OFF clear alarm)

Write example 4)

Station : 1 Address : 0000 Extra1 : R, EXTRA2 : 200

If you set as above and write digital value, you can read Run Data of no.1 S-TURBO Compressor device and save from no.200 address of WORD/FLOAT/DWORD memory. (Save at memory no.200 to no.257 address)

Analog Write

You can set operation command, BOV operating pressure and etc, by using analog write.

Analog write setting parameters are as follows :

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

2) STATION Device's STATION number ( 0 ~ 15 ).

3) Address Address to set. (Use, in case of A output command)

4) Extra1 Output command.

A : Send setting value,

U : Auxiliary PUMP ON,

W : Compressor Operation ON,

Y : Forcing No-Load,

Z : Forcing Load,

E : Emergency Shutdown ON,

G : Alarm Check,

H : Alarm Clear,

R, S : Run/Set Data read command

5) Extra2 R, S output command : Memory start address to save read value, Etc Output Command : Don't care

Write example 1)

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

If you set as above and write digital value, you can ON compressor operation of no.1 S-TURBO Compressor device. (Any value do motion of compressor operation ON)

Write example 2)

Station : 1 Address : 0000 Extra1 : S, EXTRA2 : 300

If you set as above and write digital value, you can read Set Data of no.1 S-TURBO Compressor device and save from no.300 address of WORD/FLOAT/DWORD memory. (Save at memory no.300 to no.357 address)

3. Communication cable connection of S-TURBO Compressor device

RS-485 communication cable connection

Connect RS-485 communication cable to Port2(Under side) of <Figure 4>, as follows.

Computer side S-TURBO Compressor side

Tx+, Rx+ -------------------------------------- No.3 pin

Tx-, Rx- ---------------------------------------- No.2 pin

Notice) 4 wire RS-485 cable can be used according to S-TURBO Compressor device. ( 2 : Rx-, 3 : Rx+, 4 : Tx+, 5 : Tx- )
