1.17 WRITE: Write file (as from SW 4.3)

Using the WRITE command, data (e.g.

measurement results for measuring cycles) can be

appended to the end of the specified file.

The maximum length in KB of the log files is set via

MD 11420 LEN_PROTOCOL_FILE. This length is

applicable for all files created using the WRITE

Once the file reaches the specified length, an error

message is output and the string is not saved. If there is

sufficient free memory, a new file can be created.

The created files can be

• read, edited and deleted by all users,

• written in the part program that is currently being

The blocks are inserted at the end of the file, after M30.

Programming example

N10 DEF INT ERROR

N20 WRITE(ERROR,"TEST1","LOG FROM

N30 IF ERROR

N40 MSG ("Error with WRITE command:"

WRITE(ERROR,

"/_N_WCS_DIR/_N_PROT_WPD/_N_PROT_MPF",

"LOG FROM 7.2.97")

Additional notes

• If no such file exists in the NC, it is newly created

and can be written to by means of the WRITE
