If it is exceeded an error message is output and the block or data isnot saved. If there is sufficient free memory, a new file can be created.ExamplesExample 1: WRITE command into the passive file system without absolute path dataExample 2: WRITE command into the passive file system with absolute path dataNoteWhen writing into the passive file system of the NCK, the WRITE command implicitly insertsan "LF" character (LINE FEED = new line) at the end of the output string.This behavior does not apply for output on an external device/file. If an "LF" is also to beoutput, then this must be explicitly specified in the output string.→ also refer to example 3: Implicit/explicit "LF"!Program code CommentN10 DEF INT ERROR ; Definition of errorvariables.N20 WRITE(ERROR,"PROT","LOG FROM 7.2.97") ; Write the text from "LOGFROM 7.2.97" to file_N_PROT_MPF.N30 IF ERROR ; Error evaluation.N40 MSG ("Error with WRITE command:" <N50 M0N60 ENDIF...Program code...WRITE(ERROR,"/_N_WKS_DIR/_N_PROT_WPD/_N_PROT_MPF","LOG FROM 7.2.97")...
