Abstract
The invention relates to the field of screen printing, and specifically relates to a multicolor screen printing control system based on MODBUS. The system comprises a touch screen, and the touch screen is connected with a COM1 port of a main station PLC through an RS232 serial port. The main station PLC controls one servo driver, thereby controlling a servo motor which is used for longitudinal feeding. Meanwhile, the main station PLC communicates with each slave station PLC through an RS485 port. In order to achieve coordinative control in a multi-PLC control system, the PLCs are connected with each other through a main-slave network. In other words, one PLC is selected as the main station, and the remaining PLCs are slave stations, wherein the main station manages the slave stations and initializes the communication. However, the slave stations receive the management, and responds to the communication. The system easily achieves the centralized management and monitoring, is high in safety, is more suitable to serve as a control network and an equipment network, and employs the main-slave network. Four stations are the slave stations, and one station is the main station. The main and slave station PLCs employ the MODBUS communication protocol to achieve communication. The system takes the touch screen as a man-machine interface, and achieves data display and operation control.
