The standard application can be used with the appropriate Bristol® ControlWave® PLC/RTU, from Emerson Process Management to meet the I/O requirements at the various sites. The combined solution offers a cost effective system that is ready to deploy without the typical programming overhead. Benefits Pre-programmed package eliminates the need • for custom programming One package for one to three pumps provides • consistency for operators and technicians Local Display/Keypad Operator Interface panel • for on-site system control Alarm and historical data reporting for full • SCADA integration Multiple pump scenarios allow flexibility to meet • a wide range of applications Pump start/stop as well as VFD speed control• Easy-to-use web page station configuration and • setup Easily interfaces to field devices and sensors• Security and water quality functions can be • easily added as needed Plant managers will take maximum advantage of the flexibility and maintenance personnel will appreciate the simplicity of the Bristol ControlWave pump control application. All remote water and wastewater applications have the same requirements to automatically control one or more pumps to maintain level, pressure and/or flow. Some sites may also have the need to control chemical feed, measure rain level, and detect intrusion events. All of these are pre-programmed and available for use to customize for the specific site. When the application requires modifications or additions to the standard program, Bristol ControlWave Designer allows unlimited customization by your engineering staff or other integrators.

The assemblies are fully integrated units that combine the PLC/RTU with a variety of options commonly required in SCADA applications. These include a NEMA 4X rated enclosure, power supply and battery backup options, termination options, display and operator input options, and wireless communication options. The ControlWave SCADA packages with the pre- programmed pump controller application are ideal for integrating remote site measurement and control into the SCADA system. Station Control Strategies: Level control Pressure control Time control Pump lead/lag and pump alteration Pump interlock and permissive conditions Manual and PID VFD Control Historical Archive Historical data is stored in three archive files in the ControlWave PLC/RTU flash memory. This ensures maximum data integrity even in the event of a SCADA communication network failure. The historical data archives may be collected periodically on a scheduled or demand basis by the OpenBSI Harvester utility. This technique also minimizes communication bandwidth requirements significantly benefiting radio and cellular network architectures. Daily Archive: Stores 35 days of time-stamped minimums, maximums, averages and totals Hourly Archive: Stores hourly time-stamped minimums, maximums, averages and totals Trend Archive: The Trend Archive stores instantaneous values at a fixed period from one minute to sixty minutes. Setup and Configuration As mentioned earlier, the ControlWave pump control SCADA application is pre-programmed. The unit only needs site specific configuration through the easy-to-use set of web pages supplied with the application software. These configuration web pages are accessible through the OpenBSI TechView utility. TechView allows easy connection to any ControlWave PLC/RTU through serial or Ethernet ports. The utility is essentially a web page browser that ...
