Project Requirements

A municipal water supply company in Romania intends to upgrade their groundwater pumping and water storage system with a modern SCADA solution. This system includes ground water extraction and pumping, chlorine water treatment, water storage in tanks, and pumping drinking water to a major city and to an industrial park.

The current SCADA system uses two-way radios for data transmission between locations, which are a few kilometers away from each other. The main requirements are to upgrade the outdated SCADA software, replace the old monitoring and control devices, implement TCP/IP data tansmission via fiber optic, and keep the existing radio system as a backup. The customer requests equipment designed for harsh conditions, surge and lightning protection, 24/7 system availability, autonomous and manual control, a modern SCADA system with remote access functionality, and long-term availability for spare parts.

 

ICP DAS Solution

The ICP DAS solution met all project requirements and the previous SCADA system was upgraded without affecting the pumping system operation.
ICP DAS products for data acquisition and control proved to be a high quality and cost-effective solution for implementing the project, allowing great flexibility by meeting industrial standards like Modbus TCP and Modbus RTU.

The VP-25W9 programmable automation controllers powered by Windows CE 5.0 and InduSoft Web Studio were used for monitoring and controlling important nodes in the system, thanks to the high reliability and ability to function in harsh environments. The InduSoft Web Studio runtime allows the unit to act both as a PLC and HMI, with great flexibility and the ability to access the runtime remotely.

The tGW-700 Series gateway modules allowed to implement redundant data transmission via fiber optic (Modbus TCP) and via radio (Modbus RTU/RS-232). The InduSoft WebStudio runtime proved to be very versatile and allowed the use of both interfaces, and also switch between them automatically when needed.

I-7510AR repeaters were used to connect the equipment at each groundwater pumping location on the long RS-485 bus. Thanks to the three-way isolation provided by the repeater, the equipment is protected against surges caused by lightning storms.

Indusoft Web Studio is a very versatile and cost-effective SCADA platform, providing local operator interface, remote web thin client access and mobile access. Future development and upgrading is an easy task.
