CNC_CDNC | PROGRAM

Description

Sends NC command data to CNC(for DNC operation).

When the data processing on the CNC side is delayed and the next data cannot be transferred, error(EW_BUFFER) is returned.
If an application will wait the data transferring, use the cnc_dnc function.

Except the above-mentioned difference, function is the same ascnc_dnc, so refer to cnc_dnc function for other description.

Note1) The G130 function of Power Mate i-H cannot be used.

Declaration

Arguments : HSSB

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_RESET (-2)	Reset or stop request 'RESET or STOP' was pushed. Call the cnc_dncend function.
EW_FUNC (1)	cnc_dncstart function has not been executed.
EW_LENGTH (2)	Data block length error Length of data block(number) exceeds 256 bytes. (In case of High Speed DNC of Series 16/18/21, 16i/18i/21i, 0i : 40959 bytes)
EW_BUFFER (10)	Buffer empty/full Retry because the buffer is full.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

For HSSB connection,

The extended driver/library function is necessary.

CNC parameter

This function is related to the following CNC parameter.
See the manual of CNC parameter for details.

• Series 15
0020 = 15 (must be set)
0000#0 (influenced by setting)


• Series 16/18/21, 16i/18i/21i, 0i
0000#0 (influenced by setting)
8706#0 (influenced by setting) (This parameter is effective only in path 1. Set 0 except the 1st path.)


• Power Mate i
0000#0 (influenced by setting)

CNC mode

• Series 15
It is necessary to set TAPE mode.


• Series 16/18/21, 16i/18i/21i, 0i, Power Mate i
It is necessary to set MEM mode, and "DMMC" signal(DI), G042#7=1.
