1.1 Variables
Example
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
REDEF $TC_DPC1 INIPO (100, 101, 102, 103)
; 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.

General conditions
Granularity
A redefinition is always applied to the entire variable which is uniquely identified by its name.
Array variables do not, for example, support the assignment of different attributes to
individual array elements.
