Water Treatment Plant Automation

Customer : Water Treatment Plant
Segment   : Water Treatment


This was a Water Treatment plant with multiple filters in series operation. Scope of Cotmac was to develop the application software for monitoring and controlling a water treatment system. The automation system was Siemens S71500 PLC, Siemens HMI with G120 VFD to control and monitor the water treatment system.

The project was divided into two parts :

  • RO System
  • Filter System

Both section had individual S71500 PLC and HMI. The PLC system was communicating on Profinet with HMI & VFD. HMI programming was done with TIA V13 SP1 for comfort panel TP1200.

  • Network & Control panel drawings
  • PLC & SCADA Engineering
  • FAT
  • SAT Support

S7-1500 CPU 1515 PLC, HMI TP 1200, G120 VFD

  • Long term data storage archives, which can be utilized for plant optimization and predictive maintenance.
  • Facility for straight forward real-time simulation of processes.
