PLC automatic control system

Water and electricity become an indispensable means of of human life, saving water and power have become more and more important than before. the application of PLC automatic control system in XST water treatment technology, which has a very important significance to improve the production efficient

PLC selection

PLC automatic control systems for water treatment technology

 

 

 

 

 

 

 

 

The PLC has two types control system, site control and control center, both of them have manual and automatic control mode, manual control mode is a supplement to automatic mode convenient to control system, provide the conditions for the maintenance of the system..

Real time monitoring

Real time monitoring is to recording and processing the alarm signals and parameters in the working site. Among them, the switching process diagram, the control center can provide dynamic interface related to multiple water treatment , can understand the full range of equipment, and the operation condition of each segment, the interface can switch at any time; monitoring of working process, control operating personnel, data can be set to the operation of the valve, control   and the selection of stop or start.
Alarm processing

When fault occurs, the system will appear commands set in the previous, make a preliminary analysis of the accident, and the alarm screen remind the operator to prompt.

Trends analysis

In the control center,  provides us a trend display screen, display two trend of  real-time and historical, history shows the past work state, is conducive to the staff view about the trend of the past Real time trend is to record the equipment current change in the process, showing the continuous trend curve , Can also read the actual data at any point, convenient observation of staff.
