Daisy Ave. <br />Santa Ana, CA 92703 <br /> <br />RE: SCADA System Auto-Dialer Upgrade Review Proposal <br /> <br />Nabi1, <br /> <br />This proposal is to have Heavens Systems review your existing auto-dialer system and <br />recommend a replacement. Due to data throughput limitations, the path for upgrade is <br />being reviewed to come up with the best solution for your installation. Potential paths <br />include implementing an "off the shelf' auto-dialing software that interfaces with your <br />present PLC or implementing an "Off the shelf' package and adding a layer of software <br />to allow the system to pull database type information from your existing SCADA system. <br /> <br />The on-site review will address: <br /> <br />· Communications issues between the existing SCADA system and the local <br />Modicon PLC. <br />. SCADA system database interface capabilities. <br />· Auto-dialer applications on the market today that meet your needs. <br /> <br />The completed review will be turned in with a report suggesting applications software, <br />implementation methods and estimated costs. The cost for the aforementioned system <br />review is $2400.00. This cost is based on 24 hours for review and testing for your <br />system. <br /> <br />1fyou have any questions regarding this proposal, feel free to call, page or email me for <br />further information.
