7 Code conversion function

FBDN1/7-140 Motion Control Information System DNC (FBDN) - 04/10 Edition

7.1 Code conversion

General

DNC uses NC programs in ASCII code. Data is always downloaded/uploaded in

the code required by the CNC machine tool. If necessary, the code may have to be

converted. The DNC code conversion server supports three types of code:

 ASCII code

 ISO code

 EIA code

To download/upload NC programs in a particular code, the code must be converted

via a code conversion table, which allows characters to be converted individually or

filtered out.

Code conversion tables

The CODES.TXT file in the program directory contains all the code conversion

tables. A table is defined for each code type and transmission direction. It begins

with its name, which comprises the code type and transmission direction (OUT =

download; IN = upload). The table content is enclosed by { }. Each row in the table

comprises a series of assignments, whereby an output value is assigned to an

input value. An assignment is made as follows: #2A AA '*'

# Start of assignment

2A Two-digit input value in hex

Blank used as separator

AA Two-digit output value in hex

Blank used as separator

'*' Mnemonic as comment

Two blanks used as separator

The code conversion table can also be used to hide certain characters. For this

purpose, FF must be entered as the output value.

Note

The offset must never be changed; if it is changed, this could result in non-

initializations or incorrect initializations.

Note

Each station is only assigned one code conversion file (CODES.TXT).

Any changes made in one of the six code conversion tables only affect machines

that use this code type.
