SCADA RTU

SCADA Packages

The Bristol ControlWave Micro and ControlWave ExpressPAC integrated SCADA packages, from Emerson, are designed and built for out-of-the-box installation and startup. 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 en- closure, power supply and battery backup options, termination options, display and operator input op- tions, and wireless communication options.

ControlWave MIcro

PLC/RTU SCADA Package

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 his- torical 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, maxi- mums, 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 ap- plication 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 really simplifies menu navigation and PLC/RTU configuration.
