Abstract
This work is presenting a control system for starting up the D.C. motors with separate excitation, built in both wired and programmed logic. The electrical control diagram in programmed logic was performed by means of a programmable logical controller (PLC), TWIDO type, produced by Schneider. Through the usage of the TWIDO PLC a control system with better functioning performances is obtained, compared to the wired logic control system.
