Device part of <Figure 1> input Com Port(COM1), Baud Rate(4800), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to setting of controller.
Note) Station, baud rate of MIRAE MR8000 Series can set by using front panel's setting button. ( refer to chapter 4 )
MIRAE MR8000 Series communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 0 ~ 63 station number.
2) Read command – command = 00 ~ 07, 11 ~ 1G. ( 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.

MIRAE MR8000 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 at
<Figure 1>, you
can see the dialogue box such as <Figure 2>. you can also set read schedule by
using this part.
 |
| <Figure 2> Example of MIRAE MR8000 Series communication driver’s Option dialog box |
You can set read schedule by using 
, 
, 
button and listbox of <Figure
2>.
 |
| <Figure 3> Example of MIRAE MR8000 Series 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 and write 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 0 ~ 63 station number.
3) ADDRESS data saving start address when read command. ( refer to <Table 1> )
4) Extra1 read/write command = 00 ~ 07, 11 ~ 1G read command( refer to <Table 1> ), 41 ~ 45, 51 ~ 5G : write command.
5) Extra2 0 ~ 3 decimal point when write command.
Write example 1)
PORT:0, station:0, ADDRESS:0000, Extra1: 41, Extra2 : 0
The setting parameter shown above is Alarm 1 value setting example with 0 decimal point.
Write example 2)
PORT:0, station:0, ADDRESS:0000, Extra1: 42, Extra2 : 1
The setting parameter shown above is Alarm 2 value setting example with 1 decimal point.
Write example 3)
PORT:0, station:0, ADDRESS:0000, Extra1: 51, Extra2 : 0
The setting parameter shown above is Sensor Input Type( 0 ~ 9, refer to <Table 2> ) setting example.
Write example 4)
PORT:0, station:0, ADDRESS:0000, Extra1: 5G, Extra2 : 0
The setting parameter shown above is OutScale Low value setting example with 0 decimal point.
Write example 5)
PORT:0, station:0, ADDRESS:0150, Extra1: 00, Extra2 : 0
The setting parameter shown above is PV value reading example.
After reading, the readed value save at 150 WORD, DWORD, FLOAT memory.
Write example 6)
PORT:0, station:0, ADDRESS:0230, Extra1: 13, Extra2 : 0
The setting parameter shown above is Rnage Low value reading example.
After reading, the readed value save at 230 WORD, DWORD, FLOAT memory.
