Synchronous real time control of distributed servo drive systems by way of device net network

In this study, simultaneous and real-time control of distributed servo drive systems is provided. Behaviors of each drivers was investigated under various loads and without a load in the study. In the implementation phase, PLC is used as a controller and SCADA is used for monitoring and controlling. Device-Net, an industrial communication protocol, is used between PLC and SCADA. Beside the property of SCADA and servo drive systems working in a coordinated manner, both local and central control is provided. Optimum P (proportional gain), I (Integral gain) and D (differential gain) of AC servomotors which are used for position and speed control were obtained by the automatic tuning feature. By entering the obtained values into PID function located in PLC, minimum exceeding, maximum elevation, minimum settling time for simultaneous location and speed control for ac servomotors were provided to be obtained.
