Automation Systems and Controls , a Mitsubishi Electric Factory Automation distributor based in Victoria, Australia has become a reliable partner for irrigation control solutions.
Automation Systems and Controls have been assisting clients improve their remote rural irrigation control by bringing together the innovative standard features of Mitsubishi Electric’s FX3G programmable logic controllers (PLC) and 700 Series variable speed drives.
Direct monitoring of irrigation controls can be time consuming and expensive. While advantages of remote monitoring solutions are understood, existing irrigation control solutions are often quite expensive and typically require site visits by technicians to carry out fault analysis or changes to operating parameters.
Irrigation control solutions delivered by Mitsubishi Electric allow the ability to access the variable speed drive parameters, performance and control remotely with a reliable, simplified and economical system.
David Shead of Automation Systems and Controls says that further cost reductions can be achieved where more than one variable speed drive exists with this solution allowing up to eight variable speed drives to communicate to one controller.
The Mitsubishi Electric solution enables this through the simple interface and connection of the variable speed drive to the PLC, using the FX series RS-485 ‘inverter communication’ feature through a low cost FX3G-485 BD inner board.
Both FX3G and FX3U programmable logic controllers contain inverter write and inverter read applied instructions, providing for transparency between the controller and inverter.
A suitable modem connected to the PLC such as a 3G modem that can also operate on GSM, GPRS and Edge networks completes the package to provide a communications interface for the remote program control and monitoring solution.
