Monitoring system combining PLC with Kingview
for H2S concentration
ABSTRACT
Programmable Logic Controller (PLC) is a kind of automatic control equipment which is widely used in the industrial manufacture. It merges the traditional control technology, computer and communication technologies with a strong ability to control, flexible operation, high reliability and suitable for long-term characteristics of continuous work. It is very suitable for temperature control requirements.
In the industrial field, with the rapid increase in the degree of automation, it is more and more important to monitor the process of control system for the users. The emergence of human-machine interface meets the needs of users. Human-machine interface can comprehensively monitor the control system, including process monitoring, alarm, data logging and other functions, so that the control systems have become user-friendly operation, the process of visualization and it will play more and more important part in the field of automatic control.
This essay mainly introduces a design of monitoring system combining Rockwell programmable logic controller (PLC) and configuration software Kingview which is developed by Beijing Yakong Company. When programming, we use the RSLogix5000 software operates to the H2S Controller. In order to monitor the control system and process data in actual time, we designed Human Machine Interface(HMI)with the configuration software Kingview. The result of experiment proves that this monitoring system could run quickly, accurately and have good stability, which is the advantage of the monitoring system. This monitoring system has been widely used in the industrial concentration monitoring field.
