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.
Also you can input wether 'analog read data is hex format' (0 : float, 1 : word, default = 0), 'check enable/disable of CRC' (1 : enable, 0 : disable, default = 0) by using option part.
Note) You can set controller's station address, baud rate, EXPERT
EX9000 DIO/AIO Series by using communication setting of
INIT switch( Refer to: chapter 4)
EXPERT EX9000 DIO/AIO Series communication driver’s read schedule
Read schedule setting parameters are as follows:
1) Station – Controller station number = 0 ~ 255.
2) Read Command – Command = AIN, AI, DI, DO, CONFIG, CH_STS, CH_DATA. ( Refer to <Table 1> )
3) Read Start Address – Read channel number( 0 ~ ) when AIN read command.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Fixed to 1.
AIN : 1 FLOAT/WORD data,
AI : All channel data read, 1 ~ n FLOAT/WORD data,
DI, DO : 1 WORD data,
CONFIG : 4 WORD data,
CH_STS : 1 WORD data,
CH_DATA : All channel data read, 1 ~ n WORD data

2. Writing settings
You can write the setting value by using write settings.
Digital Write
Digital write(for digital input Tag) setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 0 ~ 255.
3) ADDRESS Writing address = 0 ~ 16.(decimal unit)
4) Extra1 Write command = DO, or space.
5) Extra2 Don't care.
Write example 1)
PORT:0, Station : 1, Address : 0000, Extra1 : DO, EXTRA2 :
The setting parameter shown above is a control(On/Off) example of 0(1st)
DO for 1 station EXPERT EX9000.

4. INIT Mode setting method of EXPERT EX9000 DIO/AIO Series
Init Mode setting method of EXPERT EX9000 DIO/AIO Series is as follows.
EX9000 Series controller can set baud rate, station address, etc.
When you want set default (this call 'Init Mode') baud rate, station adddress, etc, you can set 'Init Mode' in the following order.
1) Power off
EX9000 Series controller.
2) Connect 'INIT Mode' pin. ( EX9017F = JPA
pin, )
3) Power on EX9000 Series controller.
4) Communicate with EX9000 Series controller with
9600 bps, 0 station address.
5) Power off EX9000 Series controller and disconnect 'INIT Mode' pin.
Controller's baud rate and station address of after 'INIT Mode' setting
baud rate
: 9600 bps
controller station address : 1 ( or 0 according to
controller type )
