Monitoring and control of PLC based motion control systems via device-net

The control of mechanical systems are generally applied by using electric motors which are useful for the control of velocity, position and torque. On the other hand, servo motors are preferred due to their characteristic properties for the systems that require more accurate operations. In this study, a mechanical prototype having a two degree of freedom motion capacity integrated with AC servo motors is generated. The control of those AC servo motors is achieved by using an Omron PLC (Programmable Logic Controller). A SCADA program is developed for user control and monitoring. The connection between SCADA and PLC is obtained by using Device-Net web protocol. The velocity and position of the motion control system are monitored with real time animation on the screen. It is observed after the testing of the designed system that the position and velocity values are convenient.
