CNC_RDCOMMAND | MISC

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

Specify the commanded data.

Specify the block to be read.

Pointer to the number of commanded data to be read. Specify the number of commanded data to be read before function call, and the number of commanded data which was/were read actually is stored after the function call.

Specify the address of the array of ODBCMD structure including the commanded data. The number of array must be 1 for reading data one by one. The number of array must be the number of commanded data to be read (*num_cmd) for reading all data at a time.

typedef struct odbcmd {
    char  adrs ;          /* command address */
    char  num ;           /* M code number or axis number */
    short flag ;          /* additional information */
    long  cmd_val ;       /* commanded data */
    long  dec_val ;       /* decimal point of commanded data */
} ODBCMD ;

Refer to the following explanation about the ODBCMD structure.

(1) Reading the modal data except G code

The readable modal data are commanded data D, E, F, H, L, M, N, O, S, T, and second auxiliary function (A, B, C, U, V, or W).

• Reading data one by one
  

Specify 1 for "num_cmd". Specify the commanded address in the following table for "type". Specify the block to be read for "block". Then modal data except G code in the objective block specified by "block" is set in the ODBCMD structure.

type	commanded address	type	commanded address
0	A (2nd auxiliary function)	15	P (not used)
1	B (2nd auxiliary function)	16	Q (not used)
2	C (2nd auxiliary function)	17	R (not used)
3	D	18	S
4	E	19	T
5	F	20	U (2nd auxiliary function)
6	G (not used)	21	V (2nd auxiliary function)
7	H	22	W (2nd auxiliary function)
8	I (not used)	23	X (not used)
9	J (not used)	24	Y (not used)
10	K (not used)	25	Z (not used)
11	L	26	M (2nd M code)
12	M	27	M (3rd M code)
13	N	28	M (4th M code)
14	O	29	M (5th M code)

The following data are set in the ODBCMD structure.

adrs

The commanded address is stored in ASCII code.

num

The following values are stored when "adrs" is M (=77).

1	:	1st M code
2	:	2nd M code
3	:	3rd M code
4	:	4th M code
5	:	5th M code

flag

The following flags are stored.

#3	=	1	:	command differ from the previous block (only Series 30i, 0i-D/F, PMi-A)
#4	=	1	:	There is a command of a decimal point.
#5	=	1	:	Negative
#6	=	1	:	1 digit
#11	=	1	:	There is a command after RESET.
#15	=	1	:	There is a command in the present block.

cmd_val

The commanded data is stored.

dec_val

The number of places of decimals of commanded data is stored.

The commanded data is calculated by the following expression.

   Commanded data = cmd_val * 10 ** (-dec_val)

(Example) The following data are read when "F1000.0" is commanded.

adrs	=	F (=70)
cmd_val	=	10000
dec_val	=	1



• Reading all data at a time
  
Specify the number of modal data to be read for "num_cmd". Specify -1 for "type". Specify the block to be read for "block". Then all modal data except G code in the objective block specified by "block" is set in the ODBCMD structure.Specify the number in the following table for "num_cmd" in order to read all modal data. The number of modal data which were read actually is stored in "num_cmd" after the function call.

Some same M codes may be read at a time with "multiple M commands in a single block".

	With "2nd auxiliary function"	Without "2nd auxiliary function"
With "multiple M commands in a single block"	15	14
Without "multiple M commands in a single block"	11	10

(2) Reading commanded data

• Reading data one by one
  

Specify 1 for "num_cmd". Specify the commanded address in the following table for "type". Specify the block to be read for "block". Then commanded data which is commanded in the objective block specified by "block" is set in the ODBCMD structure. When no data is commanded in the objective block specified by "block", zero is set in "num_cmd".

type	commanded address	type	commanded address
100	A	115	P
101	B	116	Q
102	C	117	R
103	D	118	S
104	E	119	T
105	F	120	U
106	G (not used)	121	V
107	H	122	W
108	I	123	X

cmd_val

The commanded data is stored.

dec_val

The number of places of decimals of commanded data is stored.

• Reading all data at a time


Specify the number of commanded data to be read for "num_cmd". Specify -2 for "type". Specify the block to be read for "block". Then all commanded data in the objective block specified by "block" is set in the ODBCMD structure. Specify the number in the following table for "num_cmd" in order to read all commanded data. The number of commanded data which were read actually is stored in "num_cmd" after the function call.

(3) Reading commanded data concerning axis

• Reading data one by one


Specify 1 for "num_cmd". Specify axis number (200 to 223) in the following table for "type". Specify the block to be read for "block". Then commanded data concerning axis which is commanded in the objective block specified by "block" is set in the ODBCMD structure. When no axis is commanded in the objective block specified by "block", zero is set in "num_cmd".

type	axis
200	1st axis
201	2nd axis
:	:
209	10th axis
210	11th axis
:	:
222	23th axis
223	24th axis

* When MAX_AXIS=15, type=215,..,223 are not used.
* When MAX_AXIS=10, type=210,..,223 are not used.
