A typical automatic bus transfer control system is designed based on S7-200 PLC. The system can automatically identify the actual operation and then take appropriate automatic bus transfer action by analyzing the collected digital signals. Besides, the system has the functions of warning and display. When the power supply system breaks down, it will alarm and cut off faults immediately, thus can meet the demands of users toward power supply quality.
