DAIKIN SUT Series Communication Driver

DAIKIN SUT Series communication driver is driver to communicate with Hybrid hydraulic systems of DAIKIN industries, Ltd. in Japan.

1. Read settings

<Figure 1> is read setting example of DAIKIN SUT Series communication driver.

<Figure 1> Read setting example of DAIKIN SUT Series communication driver

 Device part of  <Figure 1> input Com Port(COM1), Baud Rate(19200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, accordint to the setting of system.

Read schedule of DAIKIN SUT Series communication driver

Read schedule setting parameters are as follows:

1)    Station – don't care.

2)    Read command – fixed to MD.

3)    Read start address – reading memory address. ( refer to <Table 1>)

4)    Save start address for Communication Server – Saving start address of Communication Server.

5)    Read size – fixed to 1.

Read schedule example)

READ, 0, MD, 0, 0, 1,
READ, 0, MD, 2, 1, 1,
READ, 0, MD, 8, 2, 1,
READ, 0, MD, 10, 3, 1,

<Table 1> is memory address and parameter of DAIKIN SUT Series communication driver.

<Table 1> Memory address and parameter of DAIKIN SUT Series communication driver

DAIKIN SUT Series communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE( also save STRING for alarm command ) memory, but the data format are 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> Example of DAIKIN SUT Series communication driver’s Option dialog box

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

<Figure 3> Example of DAIKIN SUT Series communication driver’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. Write settings

You can set DAIKIN SUT Series controller by using 'write settings'. 

Digital Write

Digital write and analog write have the same setting parameters except output value. 

Analog Write 

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             don't care.

3)  ADDRESS          writing memory address( decimal unit ). ( refer to <Table 1> )

4)  Extra1                  fixed to SD.

5) Extra2                   don't care.

Write example 1)

PORT : 0   STATION : 0   ADDRESS : 0055  EXTRA1 : SD  EXTRA2 : 0

The setting parameter shown above is flowrate setting example for lower voltage.

Write example 2)

PORT : 0   STATION : 0   ADDRESS : 0056  EXTRA1 : SD  EXTRA2 : 0

The setting parameter shown above is pressurized time setting example.
