DONGA Hitech Smart RPPS communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number = 0 ~ 15.
2) Read Command – Command = CURR, SET. ( Refer to <Table 1> )
3) Read Start Address – 0 ~ 9 setp number when 'SET' read command, other command = Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1.

DONGA Hitech Smart RPPS communication driver store the same data in WORD, DWORD, FLOAT memory, but the data format are different.
If you click the icon 
in protocol option part, you
can see the dialogue box such as <Figure 2>. you can also set read schedule by
using this part.
 |
| <Figure 2> Example of DONGA Hitech Smart RPPS communication driver’s Option dialogue box |
You can set read schedule by using 
, 
, 
button and listbox of <Figure
2>.
 |
| <Figure 3> Example of DONGA Hitech Smart RPPS communication driver’s read schedule Add/Edit dialogue box |
When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can write the setting value by using write settings.
Bit Write
Bit write and word write have the same setting parameters except output value( 0 or 1 ).
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 0 ~ 15.
3) ADDRESS Write address.( decimal )
STATUS write command : 0 , 1, 2, 10, 30, 31, ( Refer to <Table 3> )
SET write command : 0 ~ 9 setting type selection. ( Refer to <Table 4> )
4) Extra1 Write command = STATUS - write of register status, SET - write of setting value.
5) Extra2 Step number when SET write command.
<Table 3> is output value and contents of STATUS write command according to address, <Table 4> is output value and contents of SET write command according to address.
| Address | Contents | Output value |
| 0 | ON/Pause of rectifier | ON(1) = ON, OFF(0) = Pause |
| 1 | Setting of operation mode | ON(1) = CC mode, OFF(0) = CV mode |
| 2 | High/Low setting of CC mode | ON(1) = HIGH, OFF(0) = LOW |
| 10 | Setting of end step number | 0 ~ 9 end step number |
| 30 | Ah Reset | ON(1) = Ah Reset, OFF(0) = don't use |
| 31 | Stop | ON(1) = Stop, OFF(0) = don't use |
