Design of the ABU-Robot Control System Based on S7-200 PLC
Abstract: An automatic control system of ABU Robot based on S7-200 PLC is designed on the basis of ABU Robot match requirement. The main hardware of the system, the principle and method of control and the S7 -200 PLC program architecture are introduced in this paper. PID algorithm is adopted in the system, and the function of non-disturbance switch from manual mode to automatic mode is realized according to field match requirement. The test run and try run indicates that Robot PLC control system based on PID control rule has features of stable running, convenient operation and little maintenance.
