The <br /> primary purpose of SCADA is to monitor, control and alarm plant operating systems <br /> from a central location. In a municipal context, "plant" systems are typically water and <br /> wastewater facilities. <br /> The SCADA has a computer software component that dates to 2005 and runs on two <br /> PC's with the Microsoft XP operating system. Those computers, as well as the XP <br /> operating system are near the end of their useful life. The SCADA uses an outdated <br /> version of proprietary software called Wonderware. In fact the version of Wonderware <br /> that we are using will not even run on newer releases of XP, such as Service Pack 3. <br /> Thus, if a computer failed, we would need to find the earliest version of XP to run on a <br /> replacement. In order to update Wonderware to run on a new computer with new versions <br /> of Microsoft, the City would be required to pay a license fee of more than $7000 plus <br /> installation costs. <br /> Staff has explored SCADA control software and recommends changing to Cimplicity, a <br /> product of General Electric. It is a less costly alternative and has new features not present <br /> in the Wonderware update. They include alarm notifications by email or text message and <br /> establishing categories that may include critical and non - critical alarms. These categories <br /> would allow the city to reduce its overtime costs by relieving staff from responding to <br /> minor system issues that can wait until the next work day, but still notifying staff of the <br /> status of the equipment operations. At the same time, it will page out staff for critical <br /> system failures. The system also would document when notifications were sent and when <br /> they were responded to. <br /> The cost for the Cimplicity Plant Edition software license, including installation, would <br /> be $6897. This does not include the cost to replace the two computers that operate on the <br /> system. These would be replaced at the same time at a cost of about $2000. <br /> Paul Palzer recommends that the Council approve a contract with Savage Controls to <br /> make the change and that the cost be split equally between the Water Fund and the Sewer <br /> Fund. I agree with his recommendation. <br /> Dallas Larson, Administrator <br /> 17 <br />
