Redefinitions of system variable $TC_DPC1 in the data block for machine manufacturers
Program code
%_N_MGUD_DEF
$PATH=/_N_DEF_DIR
REDEF $TC_DPC1 APWB 2 APWP 3
REDEF $TC_DPC1 PHU 21
REDEF $TC_DPC1 LLI 0 ULI 200

; Description
; Write access right: OPI = protection level 2, part program = protection level 3
; Note
; When using ACCESS files the redefinition of access rights has to be moved from
; _N_MGUD_DEF to _N_MACCESS_DEF.
; Physical unit = [ % ]
; Limit values: lower = 0, upper = 200
; The array variable is initialized with the 4 values at POWER ON.
