CNC_RDPMACROR2 | NCDATA

Description

Reads the P code macro variables(variables for the macro-executor) specified by the starting number, "stnum", and number of variables, "*num". The data is stored in "mcval" with double format. It is not influenced by setting of cnc_setpmactype function.

The value of an undefined variable is called "vacant", and it is expressed as follows.

0xFFFFFFFFFFFFFFFF

See the "PROGRAMING MANUAL" of the macro-executor for details of the P code macro variable.

Declaration

Arguments

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
EW_LENGTH (2)	Data block length error The number of P code macro variables(*num) is 0 or less.
EW_NUMBER (3)	Data number error P code macro variable number(stnum) is wrong.
EW_ATTRIB (4)	Data attribute error Type of P code macro variables(type) is wrong.
EW_NOOPT (6)	No option This function needs the macro-executor option.

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.

The macro-executor function.

For HSSB connection,

The extended driver/library function is necessary.

For Ethernet connection,

The Ethernet function and the extended driver/library function are necessary.

However, in case of Series 0i-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.
