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:
Advertising
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
