Modification of the InTouch program of the factory graphics control system

The owner's exhaust system graphic control program has some bugs and often misjudges communication abnormalities, causing the main and backup machines to constantly switch back and forth and unable to operate normally. After Engineer Longzhong modified the graphic control program and added comprehensive logic conditions, the factory exhaust system ran smoothly, and the status of the PLC could be clearly seen on the InTouch graphic control.

construction joint water leakage map control detection

To find the leak point, the factory staff have to venture into the interlayer of expansion joints in the building where there is no light at all, which is time-consuming. Longzhong assisted in optimizing the process of checking and repairing water leaks, and reversed the link map control to receive an alarm. First, he knew that there was a water leak in the expansion joint and where the leak could be located.

Map control alarm monitoring of adsorption dryer tank tank differential pressure gauge project

Use the PLC program to automatically control the measurement of the differential pressure gauge in the tank of the adsorption dryer, and send back the measured pressure difference data of the tank to the graphic control interface for monitoring. Comprehensive control of production expenditure costs.

Air compressor remote system data automatic integration and graphic control

Manual data copying is not only time-consuming, but may also contain errors. Longzhong plans to automate the integration of remote system data. Through the graphic control screen, factory staff can remotely control the status of your machinery, automatically record all instrument data, and integrate remotely!

iFIX data control clean room AHU

iFIX provides process visualization, data collection and data monitoring of production operations, enabling rapid response to production events. Through iFIX, administrators can not only clearly monitor/control the AHU air-conditioning box system of the clean room, but also set the PID value of the windmill inverter by themselves, which can be set manually or automatically output control during operation, providing user-friendly management. choose.

Factory machinery and equipment utilization rate and situation room kanban

What is the utilization rate - it is a ratio that measures the usage status of the equipment from the perspective of the equipment. The simple calculation formula for the utilization rate is (operation time/load time)*100%, which is the percentage of time that the equipment is actually running

Clean room inspection PLC automatic leakage detection detection graphic control alarm

The process of manual detection of liquid leakage in the clean room is quite time-consuming. Longzhong has many years of experience in assisting clean room automation inspections. Through the PLC program graphic control alarm design, it can automate the clean room leakage detection process and issue graphic control alarm notifications when there is a situation, helping the owner to effectively reduce labor costs.

Air compressor system integration project

An air compressor (also known as an air compressor) refers to a machine used to compress air to increase gas pressure. It is generally used in cement manufacturing, chemical plants, hydropower plants, food industry, control instruments, driving equipment, surface spraying, aircraft and automobile manufacturing, etc. It can be seen in almost all walks of life. But, did you know that it also has applications in hospitals?
