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
