Tape & DNC

image1

Tape: Specifies the physical output format of CNC codes (tape) for post processors which are setup to output paper/mylar tape format (search for mylar or DNC).

Tape format:
Variable indicates that each tape block will have a variable size, taking only the required space.
Fixed indicates that all blocks are of a given size. If a tape block is shorter than the given size, the record is blank filled to the end.
Packed is similar to fixed except that the next record is used to fill space at the end of a given record. In other words, packed tries to fit as may logical blocks on a physical record as possible. (TAPE_FORMAT)

Tape Record length: If the tape format is fixed or packed the default record size is 72,80 where the first 72 columns contain data and the records are blocked at 80 characters. This default can be altered by specifying the data portion of the record and optionally the full size. (TAPE_RECL)

Tape sequence numbering: Sequence numbering can be provided in the non-data portion of fixed length tape blocks (fixed or packed). By default, the numbering is in columns 73 to 80.Use None to have no sequence numbering. Left left justifies the sequence number, while Right right justifies it. Use Padded to add leading zeros to the sequence number field of the record. (TAPE_SEQ)

Tape end of record marker: If the tape format is fixed or packed, the end of record character or characters can be defined. If special characters must be entered, use the standard CAM-POST ^### where ### is the ASCII code of the special character. For example, ^013^010 would be the character codes for a CRLF end of record marker. Be sure to specify 3 digits when specifying the ASCII code. By default, there is no end of record marker for fixed or packed records. (TAPE_EOR)

DNC: Specifies the physical output format of CNC codes (tape) for post processors which are setup to output DNC program format (search for mylar or DNC).

DNC format:
Variable indicates that each tape block will have a variable size, taking only the required space.
Fixed indicates that all blocks are of a given size. If a tape block is shorter than the given size, the record is blank filled to the end.
Packed is similar to fixed except that the next record is used to fill space at the end of a given record. In other words, packed tries to fit as may logical blocks on a physical record as possible. (DNC_FORMAT)

DNC Record length: If the DNC format is fixed or packed the default record size is 72,80 where the first 72 columns contain data and the records are blocked at 80 characters. This default can be altered by specifying the data portion of the record and optionally the full size. (DNC_RECL)

DNC sequence numbering: Sequence numbering can be provided in the non-data portion of fixed length tape blocks (fixed or packed). By default, the numbering is in columns 73 to 80. Use None to have no sequence numbering. Left left justifies the sequence number, while Right right justifies it. Use Padded to add leading zeros to the sequence number field of the record. (DNC_SEQ)

DNC end of record marker: If the DNC format is fixed or packed, the end of record character or characters can be defined. If special characters must be entered, use the standard CAM-POST ^### where ### is the ASCII code of the special character. For example, ^013^010 would be the character codes for a CRLF end of record marker. Be sure to specify 3 digits when specifying the ASCII code. By default, there is no end of record marker for fixed or packed records. (DNC_EOR)

Write block size: This specifies whether the size of each tape record is written at the start of each tape block. If the box is selected, the size is written using two bytes followed by a space. (BLOCK_SIZE)
