7.6.2.4 SET_COM
void SET_COM(String dev,
int channel,
long sband,
int databit,
int jo,
int stopbit,
int dataStream,
int comType)
Function: Setup the COM interface
Parameters:
dev - :device name
channel - : Device channel number
sband - ：Baud Rate
databit - ：data bit 1~8
jo - ：Parity 0：none,1：Odd number,2：even
number,3：Mark,4：space
stopbit-：Stop bit 10,15,20, corresponding to
10=1,15=1.5,20=2
dataStream - ：Data flow：0：无,1：xon/xoff,2：
hardware
comType - ：COM interface communication type
232,485,422; default value is 232
Sample：
Com_m = M:1000:COM; //define the COM
interface with the motherboard number of 1000
// setup the COM interface’s first channel (i.e.
define the first COM interface with the
motherboard number of 1000)
// Baud rate is 9600,Data bit is 8,no parity, Stop
bit is 1,No data flow, communication type is 232
SET_COM(Com_m,1,9600,8,0,10,0,232);
7.6.2.5 SEND_COM
void SEND_COM(String dev,int channel,
String str)
Function: Com interface data sending
Parameters:
dev - ：Com interface device
channel - :Device channel number
str - ：Com interface data, support two formats:
1：Direct transmit string data ( send the string as it
is to the Com interface)
2：Conversion into Hex string (when it encounters
string starting with 0x or 0X, the string will be
converted into Hex format and be sent. For
example: if 0x3132 is sent, the COM interface will
receiver the string of “12”).
Example：
Com_m = M:1000:COM; // define the COM
interface with the motherboard number of 1000
SEND_COM(Com_m,1,”1234”); // send the string
“1234” to the first channel of the mother board
SEND_COM(Com_m,1,”0x31323334”); // send
the string “1234” to the first channel of the
motherboard
7.6.2.6 SEND_IO
void SEND_IO(String dev,int channel,int val)
Function：Control I/O interface
Parameters:
dev - ：io device
channel - :Device channel number
val - ：data 0 | 1
Example：
Io_m = M:1000:IO; // define the I/O interface with
the mother board number of 1000
SEND_IO(Io_m,1,0); // output low electrical level
to the first channel of Io_m
7.6.2.7 READ_IO
int READ_IO(String dev,int channel)
Function：Control I/O interface
Parameters:
dev - ：io device
channel - :Device channel number
Return：return the electrical level status of the
“channel” in the I/O interface: it is 0 or 1. Other
value is viewed as false.
