DEF CHAN REAL PHU 24 LLI 0 ULI 10 STROM_1, STROM_2
;Description
;Definition of two GUD items: STROM_1, STROM_2
;Range of validity: Throughout the channel
;Data type: REAL
PP stop: Not programmed => default value = no PP stop
;Physical unit: 24 = [A]
;Limit values: Low = 0.0, high = 10.0
;Access rights: Not programmed => default value = 7 = key-operated switch position 0
;Initialization value: Not programmed => default value = 0.0
DEF NCK REAL PHU 13 LLI 10 APWP 3 APRP 3 APWB 0 APRB 2 ZEIT_1=12, ZEIT_2=45
;Description
;Definition of two GUD items: ZEIT_1, ZEIT_2
;Range of validity: Throughout the NCK
;Data type: REAL
PP stop: Not programmed => default value = no PP stop
;Physical unit: 13 = [s]
;Limit values: low = 10.0, high = not programmed => upper definition range limit
