Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
FnS FC410 Series communication driver¡¯s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number = 0 ~ 99.
2) Read Command – Command = FLOW, CVOL, A_CVOL, M_FLOW, MASS, A_MASS, TEMP, PRES, DATE, TIME. ( Refer to <Table 1> )
3) Read Start Address – Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – fixed to 1.
Read schedule example)
READ, 1, FLOW, 0, 0, 1,
READ, 1, CVOL, 0, 1, 1,
READ, 1, M_FLOW, 0, 2, 1,
READ, 1, MASS, 0, 3, 1,
<Table 1> is read/write command and contents of FnS FC410 Series communication driver.
| Read/write command | Contents | Read/write | Remarks |
| FLOW | Read of CVOL Flow Rate | Read only | |
| CVOL | Read/write of CVOL Total | Read/Write | Write = reset to 0 |
| A_CVOL | Read/write of CVOL Acc Total | ||
| M_FLOW | Read of Mass Flow Rate | ||
| MASS | Read/write of Mass Total | Read/Write | Write = reset to 0 |
| A_MASS | Read/write of Mass Acc Total | ||
| TEMP | Read of current temperature | Read only | |
| PRES | Read of pressure | ||
| DATE | Read/write of current date | Read/Write | Write = synchronize the computer's date |
| TIME | Read/write of current time | Write = synchronize the computer's time | |

FnS FC410 Series 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 FnS FC410 Series communication driver¡¯s Option dialogue box |
You can set read schedule by using 
, 
, 
button and listbox
of <Figure 2>.
 |
| <Figure 3> Example of FnS FC410 Series 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 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 address = 0 ~ 99.
3) ADDRESS Don't care.
4) Extra1 Write command = CVOL, A_CVOL, MASS, A_MASS, DATE, TIME. ( for 302 model, Refer to <Table 1> )
CVOL, A_CVOL, MASS, A_MASS : always reset to 0,
DATE, TIME : synchronize the computer's date, time.
5) Extra2 Don't care.
Write example 1)
PORT:0, station:1, ADDRESS:0000, Extra1:CVOL, Extra2 : 0
The setting parameter shown above is an example of reset to 0 the value of CVOL Total.
Write example 2)
PORT:0, station:1, ADDRESS:0000, Extra1:TIME, Extra2 : 0
The setting parameter shown above is an example of synchronization with computer's time.
Block Write
FnS FC410 Series communication driver don¡¯t support ¡®Block Write¡¯.
You have to connect RS-485(RS-422 or RS-232C) communication cable between FnS FC410 Series and computer such as <Figure 4>.
<Figure 4> is connection example of main power line and communication cable to FnS FC410 Series controller.
