IoT based Water Treatment Plant Monitoring using RTU-ADAM-3600

Due to expanding urban population, water distribution, pumping, protection and further more maintaining water quality has become a big problem. 
In order to solve this problem Mitsubishi along with Advantech came up with a solution to implement IOT based control system to control and monitor pumping station.
Scope –

• Complete Automation for Water Treatment Plant including SCADA, PLC & HMI is provided by Mitsubishi.
• Requirement of GPRS based DNP3 RTU from customer which is not a Product range from Mitsubishi.
• Mitsubishi took the help from Advantech for the offering of the same.

Approach – 
RTU Requirement:

• Collect data from sensors DI, DO, AI
• Connect to local HMI via Modbus
• Should have DNP3 protocol
• 4G connectivity
• OpenVPN support
• OHSR needs 210 RTUs & MBR needs 4 RTU
• All these 214 RTUs should send data to MC Works64 central SCADA on DNP3 protocol using 4G connectivity via OpenVPN

Solution:

• Studied each & every requirement
• Started searching for the suitable RTU
• After a lot discussion we have proposed unique RTU ADAM-3600 which has:
• 8DI,4DO,8AI which fulfil sensors connectivity requirement
• RTU supports multiple protocols so it has Modbus & DNP3 protocol support which is the requirement for HMI & Central SCADA connectivity.
• Has 4G connectivity with external GPRS card
• Supports OpenVPN so resolved connectivity requirement from OHSR & MBR to MC Works64 central 
• ADAM-3600 is suitable product for all requirements.

Execution –

• All field IOs are connected to each RTU 
• Data collected at local HMI via Modbus TCP
• Configured for OpenVPN & DNP3
• All data from OHSR & MBR t collected at MC Works64 central via OpenVPN using 4G connectivity

Result – 

• Single RTU- ADAM-3600 with multiple features is used for this application.
• Implemented IOT based control system to control and monitor pumping station for Water Treatment plant
