Design of Filling Production Line Based on S7—300 Drug Classification

Abstract

Through the application of S7-300, HIM touch screen, DP/AS-i, ET200M, configuration programming, and screen design through the control of the production line, the sensor counts the empty bottle, the full bottle, whether the raw materials are sufficient, and whether the processing is sufficient Qualified, tested and calculated the pass rate and reject rate. The recipe can be selected via the HIM touch screen and the device can be monitored and controlled in real time. And there is a problem with real-time alarms. Introduction Nowadays, high-speed filling technology provides the best solution for many pharmaceutical companies, which not only meets the growth rate and safety of products, but also reduces the cost of packaging materials and operating costs of pharmaceutical companies[1]. With the maturity of the filling system technology, it will provide more advanced, stable and reliable pharmaceutical filling equipment for more domestic large and medium-sized pharmaceutical manufacturers, which will bring more direct cost benefits[2]. The filling system is mainly a small class of products in the packaging machine. Signal transmission to the PLC and touch screen via an external sensor, signal is sent to the PLC, calculated and logically controlled, displayed on the HMI touch screen and controlled by the conveyor, as well as the start and stop control of other originals. And enable the conveyor to be controlled off-site. PLC: Programming with S7-300 is mainly to use the main program to control motor operation through external analog sensors, counting the number of cans, and monitoring the filling materials. The subroutine calculates the alarm for the yield and the reject rate and the reject rate comparator. ET200M: Controls the conveyor belt off-site and receives analog signal input. DP/AS-i: Controls the input and output of the analog analog[3]. HIM touch screen: Controls motor operation and monitoring with multiple interfaces, accepts signal reception and display of master station and slave station, recipe selection, receiving alarm signals, and raw material monitoring and adding raw materials. Hardware Configuration and Network Establishment The configuration hardware is an important function of the STEP7 software. It is to set and modify the parameters of the PLC hardware module. The configuration hardware consists of two parts, the configuration hardware module and the setup parameters. parameters[4].
