Efficient Water Treatment and Distribution
Root cause analysis: When a process upset or disturbance occurs, it is always time consuming to find the root cause. In the past, the process engineer had to compare trend data from the screen with alarm logs. With Process Analyst, all the engineer has to do is simply add any pen (analog, digital, alarm) that could have contributed to the process upset to the display. Each process change can then be easily compared as alarms occur, enabling sophisticated analysis of the process upset.
Compare different batches: With Process Analyst, it is easy to compare different batches in a single integrated view. Any differences in the batch execution will immediately be visible.
Sequence of events: With SCADA systems, the data is distributed around a wide area and typically the RTUs collect the data at millisecond resolution, and send it to SCADA every time it is polled. The Process Analyst displays historical alarms and trends to millisecond accuracy, making it easy to determine the sequence of events.
From Water Treatment to Water Distribution
Having achieved a level of sophistication at the treatment plants – it was natural to carry on and try to achieve the same level of control in the distribution system. The early development of telemetry was fraught with the problems of low data transmission speed, high latency, and the unreliability of radio or leased line communications used. The latest technologies including GSM, GPRS have simplified and stabilised the entire processes.
Need for Server Clusters
On the IT front, there is a need for Server Clusters capable of cross-supporting each other – such that one server may be the hot-standby server for many distributed local servers, or any combination of primary and hot-standby roles may be assigned to best suit the distributed network requirements.
