Description
Reads the P code macro variable (variable for the macro-executor) specified by "number". The data is stored in "ODBPM" with signed binary format.
It is possible to exchange the type of P code macro variable by cnc_setpmactype function. In case of the integer type variable, this indication is invalid and always regarded as the decimal form floating-point type.
- decimal form floating-point type (data format=M*10**(-E))
- binary form floating-point type (data format=M*2**(-E))
mcr_val | : | value of variable (=M) 4-byte binary data with sign (available range:999999999,..,-999999999, integer type:-32768,..,32767) |
dec_val | : | number of places of decimals (=E) 2-byte binary data with sign (available range:-128,..,127, integer type : 0) |
mcr_val always returns by nine digits and adjusts the amount with the value of dec_val.
Example: When the variable value is 12.345, mcr_val and dec_val are read as follows.
mcr_val = 123450000
dec_val = 7
mcr_val | : | numerical part of variable (=M) 4-byte binary data with sign (available range:No limitation) |
dec_val | : | exponent part of variable (=E) 2-byte binary data with sign (available range:-128,..,127) |
The value of an undefined variable is called "vacant", and it is expressed as follows both at decimal form floating-point type and at binary form floating-point type.
mcr_val = 0
dec_val = -1
See the "PROGRAMING MANUAL" of the macro-executor for details of the P code macro variable.

Declaration
Arguments
Specify the library handle. See "Library handle" for details.
Specify the P code macro variable number. See the description of cnc_rdpmacroinfo function about the available range.
Pointer to the ODBPM structure including the P code macro variable. The ODBPM structure is as follows.
typedef struct odbpm {
long datano ; /* P code macro variable number */
short dummy ; /* (not used) */
long mcr_val ; /* value of P code macro */
short dec_val ; /* number of places of decimals */
} ODBPM ;
Return
EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.
The major error codes are as follows.
Return code | Meaning/Error handling |
---|---|
(3) |
P code macro variable number(number) is wrong. |
(6) |
This function needs the macro-executor option. |
(17) |
( Series 16i/18i/21i, 0i-A/B/C ) |
As for the other return codes or the details, see "Return status of Data window function"
CNC option
This function need the following CNC option.
And this function is related to the following CNC option.
- Series 16/18, 16i/18i This function is related to the high-speed cycle cutting option.
For HSSB connection,
For Ethernet connection,
The Ethernet function and the extended driver/library function are necessary. However, in case of Series 16i/18i/21i-B, 0i-B/C/D/F, Series 30i and PMi-A, the required CNC option is as follows. When Embedded Ethernet is used,above two optional functions are not required.
When Ethernet board is used,
- only Ethernet function is required.
CNC parameter
This function is not related to CNC parameter.
But, this function is related to the compile parameter of the macro-executor. See the "PROGRAMING MANUAL" of the macro-executor for details of the compile parameter.
CNC mode
This function can be used in any CNC mode.
