Traditionally, Garda Uno used Siemens® for its automation technology. Increasing demands for comfort, site-independent visualization, central data recording and complete documentation for years ahead could still be achieved with their current technology, at a corresponding cost. However, free networkability with any choice of third-party device, and easy service without lengthy training or costly software tools could not be achieved with Siemens®. For these reasons Garda Uno took another look at the market.
After lengthy, thorough testing and a trial phase, Saia®PCD was used for the first new projects last year. The decisive factor was the seamless integration of web and IT technologies on an industrial, freely programmable controller platform.
The first major project was to modernize 11 pumping stations and optimize their energy costs.
To do this, a Saia®PCD3.M with two memory modules was put into each station. One module serves to store the entire application software, including all events. The industrial SD flash module Saia®PCD3.R600 is used to store the entire automation project (documentation, circuit diagrams, source code, web pages for help menus, etc.) and all the pump station operating data. All data files of the Saia®PCD3 memory modules can also be called up via FTP access and opened directly from standard programs like Excel. Wide Area Automation is achieved by networking each station via Ethernet and a serial modem.
On-site operation is accessed via 10.4“ Saia®PCD Web-Panels. Any device with a browser in the Garda Uno Wide Area Network can be used without additional software for remote control and remote management (= Saia®Web-HMI).
The first major project for Garda Uno with advanced, innovative Saia®PCD technology is now in permanent operation. The customer is very satisfied with the decision to leave the path previously travelled. The next major project is already in progress.
