Upgrade for Water Pumping Station SCADA System in UAE University
In the old system, two redundant series 90-70 PLCs from GE (Hot – Standby) communicated with Versamax remote I/O over a redundant genius bus. The old PLC system monitored reservoir levels, tanks levels, flow, and pressure. In addition, there was another PLC master series 90-30 that connect to two remote RTUs on the site. The existing legacy GE system PLC and SCADA system were completely replaced with Advantech SCADA/PLC systems.
The following Advantech products were proposed and installed in the pumping station: An APAX-5620KW Intel XScale PXA270 as PLC with APAX-5017 12-Ch AI, APAX-5028-AE 8-Ch AO, APAX-5040-AE 24-Ch DI, and APAX-5046-AE 24-Ch DO. AI modules were used to manage the pump and collect information from it. The data was then sent wirelessly to the control center using Advantech a SmartFLEX SR3030 router. To manage this data feed in real time and configure the pumping stations from anywhere, an Advantech WebAccess/SCADA System was installed on an Advantech IPC-7130L workstation at the central control room.
There are many advantages of WebAccess over the existing SCADA systems like having a centralized system that is able to view, control and configure any of the pumps remotely over the Intranet or Internet from any web-browser and mobile device. Maintenance costs are significantly reduced by providing an unlimited number of clients, so there is no restriction on the amount of users or devices that can access the system, making it easy for new staff to access the system without the need for additional purchases.
By using Advantech’s cost effective solution, ETEK was able to provide a system that was easy to develop and engineer at a much more efficient level than in the previous system. With considerably less operating and maintenance costs, this total solution enables engineers to access all of the system’s pumps from university central control room. Not only is Advantech’s hardware easy to install and maintain, but with Advantech’s WebAccess SCADA solution it can be fully managed from any location. With hundreds of pre-installed drivers available for third party devices, the ability for WebAccess to manage legacy systems is unparalleled.
