CNC_WRUNSOLICPRM | UNSOLIC

Specify the library handle. See "Library handle" for details.

The parameter number for unsolicited messaging. Reserved argument, so must be set to "1".

Pointer to IODBUNSOLIC structure which sets the parameters for the unsolicited messaging.

typedef struct iodbunsolic {
    char            ipaddr[16] ;

} IODBUNSOLIC ;

ipaddr

IP address of destination PC.

ex.) "192.168.0.1"

port

TCP/UDP port number of destination PC.

The unsolicited messaging function uses TCP and UDP of the same port number.

If you set the firewall by this port number, you have to open the port for this port number.

reqaddr

PMC address type for the data transmission control. Only "R" or "E" address can be used for the transmission control, so set either "5" or "12".

5	:	R (Internal relay)
12	:	E (Extended relay)

pmcno

PMC address number for the data transmission control.

retry

Number of transmission retry to observe communication board transmits data. Set the retry count that is used when there is no answer for the data transmission.

timeout

Timeout(sec) to observe communication board transmits data. Set the time(sec) of timeout until answering to the data transmission.

alivetime

The interval time(sec)of the existence signals which are transmitted while communication board operates. Set the value less than the value of the above "timeout".

setno

Number of the Message data to be transmitted. (1-3).

type

The type of the transmitted data. This is a reserved value, so set to "1".

rdaddr

PMC address which becomes the contents of the Message data.

0	:	G (Signal to PMC->CNC)
1	:	F (Signal to CNC->PMC)
2	:	Y (Signal to PMC->machine)
3	:	X (Signal to machine->PMC)
4	:	A (Message demand)
5	:	R (Internal relay)
6	:	T (Changeable timer)
7	:	K (Keep relay)
8	:	C (Counter)
9	:	D (Data table)
10	:	M (Input signal from other devices)
11	:	N (Output signal to other devices)
12	:	E (Extended relay)

rdno

Start address number of PMC data which becomes the contents of the Message data.

rdsize

Size(byte) of PMC data which becomes the contents of the Message data. According to the number of the Message data to be transmitted(setno), maximum number which can be set to "rdsize" varies as follows.

in case of setno = 1	:	Max.1430 bytes
in case of setno = 2	:	Max.1414 bytes(total)
in case of setno = 3	:	Max.1398 bytes(total)
