29-60 CIRCUITE LOGICE DE BAZĂ CU STRUCTURĂ VARIABILĂ REALIZATE CU PORŢI ŞI-NU, SAU-NU ŞI SAU-EXCLUSIV, EXPERIMENTATE PE AP PS3


BASIC LOGIC CIRCUITS WITH VARIABLE STRUCTURE
MADE WITH NAND, NOR AND XOR GATES ON PS3 PLC
The paper presents the basic logic circuits made with integrated variable
structure NAND, NOR and XOR. The logical structure and function of these
circuits is changed by means of changeover switches which changes the logic
value of a signal at the input of XOR gates. In this way change the logic circuit
function with variable structure. Were performed experiments on the PS 3 PLC
(Klöckner-Moeller).
Keywords: logic circuits, AND – NOT gate, NOR gate, OR gate weeks
