Swampfox Communications [RTU function]

Swampfox is designed for use in telemetry systems with multiple communications channels over a number of different media including VHF/ UHF radio, line, fibre optic, cellular and IP networks. Several features unique to telemetry are included; Remotely Initiate a Message [RIM] back to the Master when an input identified as an Alarm occurs. Send Commands only once, not on every scan. Message frame numbering means that should a Swampfox not receive the message addressed to it then it will be resent from the Master.

The ability to communicate with multiple serial devices e.g. VSDs, Meters, PLCs and Displays means I/O from these can be combined, reported back to the SCADA Master, or used in logic or datalogging tasks.

Swampfox Logic [PLC function]

Programming allows the Swampfox to fulfill the role of a PLC, managing pump stations, small treatment plants and reservoirs. It is an online, realtime language which is self-documenting and simple to use. IF tests, FOR conditions and DO commands form the basis of the language which runs in the Swampfox and at Abbey Systems SCADA Master stations. Logic allows Swampfox to activate backup programs should the RTU detect there is a communications failure. Programs can be written at the SCADA Master and downloaded over the communications channel.

Swampfox Datalogging [Timestamped data storage function]

Datalogging lets Swampfox store statuses and measurements in memory for later retreival. Datalogging can be triggered in multiple ways including; time, status change, system command or derived from a logic program e.g.

		store Turbidity, Chlorine, & Bore levels every minute for Drinking Water Standards reporting
		store Pump motor currents during the motor start
		store Rainfall only when it’s raining
		store all changes when the cabinet door is open

The SCADA Master can later retrieve these automatically or manually, over the communications channel, or by using a laptop PC. They can be displayed in an Aspex trend, or exported in a CSV file or to an SQL database.

Applications

As a Pump Station Controller these three functions of RTU, PLC and Datalogger are combined to provide users with useful functions e.g. the Swampfox can operate as a Pump Station Controller.

Battery Condition monitoring

Smart battery management optimises the holdup time the Swampfox has in a Mains Fail situation and will report a failing battery before it occurs. Periodically the battery is removed from charge by the Swampfox; a load is applied and the measured battery voltage stored. This value is reported back to the SCADA Master along with several other values also recorded. Combined with the battery age and measured external series resistance [ESR] a holdup time estimate is determined and can be displayed on the SCADA HMI.

Software Tools

Local Master software tools allow the Swampfox I/O to be configured e.g. invert an input, set debounce time, latch or pulse an output, set the communications timings, also create and test local logic programs, and review I/O in connected serial equipment e.g. Meters, PLCs or Displays.

Radio Toolbox software allows users to change radio channels from the "CONFIG" port if replacing a Swampfox in the field.
