SACI JBUS communication driver

SACI JBUS communication driver is the driver to communicate with controller(IFRA) of SACI Corp.

1. Read settings

<Figure 1> is read setting example of SACI JBUS communication driver.

Device settings are fixed to Com Port(COM1), Com Baud(9600), Parity Bit(0), Data Bit(8), Stop Bit(1), respectively.

READ	STATION	Read Type	Read Address(Parameter)	Memory Save Address	Read Size
READ,	2,	W,	13038,	0,	2,
FLOAT,	2,	F,	12336,	0,	7,
FLOAT,	2,	F,	12903,	7,	10,
FLOAT,	2,	F,	12943,	17,	10,
FLOAT,	2,	F,	12983,,	27,	5,
DWORD,	2,	D,	12884,	0,	4,
READ,	1,	W,	199,	2,	1,
FLOAT,	1,	F,	222,	40,	8,
FLOAT,	1,	F,	270,	48,	10,
DWORD,	1,	D,	12336,	4,	4,

1) STATION : It is unique number which was set at each indicator. If this number is in discord with you input, communication is impossible.

2) Read Type : There is WORD, FLOAT, DWORD memory type at JBUS. Because memory type is different according to each address, if you read the value of relevant address, you have to write W when value to read is WORD and F when value to read is FLOAT and D when value to read is DWORD.

3) Read Start Address : Address position to read (Because it uses address as hexadecimal at indicator manual, use address by converting as decimal number. Refer to <Table 2> and <Table 3> for detailed memory area.)

4) Save Start Address for Communication Server : Buf position to save the read status value.

5) Read Size : The number of items to read at a time. (In case of DWORD or FLOAT, limit the read size as 10, because if the read size is over 10, timeout or other communication trouble is possible to occur)

2. Writing settings

Write to direct address of controller, regardless of SCAN File.

Digital Write

You can output ON/OFF status by using digital write.

Digital write setting parameters are as follows :

1) PORT Connected PORT number

2) Station Station number Unique number which was set at each indicator.

3) ADDRESS Address to output Output the hexadecimal value as it is in contrast with reading.

4) EXTRA2 Channel number to output It is possible to use number between 0 and 15.

Write example 1) When indicator is TMC device,

STATION:1, ADDRESS:32F1, EXTRA1:3

If you set as above, you can change Digital Output 4th channel value of TMC device.

Analog Write

You can write FLOAT or DWORD value to controller by using analog write.

Analog write setting parameters are as follows :

1) PORT Connected PORT number

2) Station Station number Unique number which was set at each indicator.

3) ADDRESS Address to output Output the hexadecimal value as it is in contrast with reading.

4) EXTRA1 Memory type of address to output W = Output 2 byte value. F = Output 4 byte value as point format. D = Output 4 byte as LONG value.

Write example 1) When indicator is TMC device,

STATION:1, ADDRESS:3030, EXTRA1:F

If you set as above, you can change Voltage value of TMC device.

3. PARAMETERS and Memory Information of SACI device

There is much parameter information at SACI device.

Address area is different for each indicator. Refer to manual which is offered when buy the indicator for etc memory information, because there is much more area, in reality.
