An Architecture Of Plc Ls Xbc-Dr30e Based Clean Water Controlling System

摘要

In the industrial field, the good controlling system is definitely required to improve the working efficiency of a system. The type of controller, PLC (Programmable Logic Controller), used in 'Clean Water Controlling System in Electrical Workshop with PLC LS XBC-DR30E'. Furthermore, such system consistently uses two types of component, they are Relay and Timer. The clean water pump control aims to pump the water in well A to storage tank B. The pump will work when water-contained well A is marked by 'sensor level well A on' and the water inside storage tank B is under level 3. When the water inside storage tank B is under level 2, both pumps (M1 and M2) will work to fill storage tank B. on the contrary, when storage tank B is above level 2, only one pump (M1) works until the tank reach level 3. In addition, when storage tank B is above level 3, both pumps will stop working. However, along with the advancement of recent technology, the above system can be controlled by using PLC (Programmable Logic Controller). Therefore, it is possible to apply the controlling method of PLC as the semester V's practical module. Based on the trial performed, the PLC-based clean water system is well-functioned as the working description compiled before the operation of the tool.
