IHI Turbo Compressor 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 3>. you can also set read schedule by
using this part.
 |
| <Figure 2> Example of IHI Turbo Compressor communication driver’s Option dialog box |
You can set read schedule by using 
, 
, 
button and listbox of <Figure
2>.
 |
| <Figure 3> Example of IHI Turbo Compressor communication driver’s read schedule Add/Edit dialog box |
When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can read data by using 'writing settings'.
Digital Write
Digital write and analog write have the same setting parameters except output value(0 or 1).
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Saving address for readed data. ( decimal unit )
4) Extra1 Command = WATCH, RECALL, TEST. ( refer to <Table 1> )
5) Extra2 Don't care.
Write example 1)
PORT:0, station:0, ADDRESS:0250, Extra1: RECALL, Extra2 :
The setting parameter shown above is a 'RECALL' read command example. After write command, the readed data save from 250 address WORD, DWORD, FLOAT memory.
Block Write
IHI Turbo Compressor communication driver don't support 'Block Write'.
