The WITS protocol, based on the generic DNP3 protocol, provides interoperability between different vendors equipment, with all the benefits that brings to the Water Industry . . .

Some WITS Key business benefits:

• Single protocol to support multiple vendors – reduced support / training costs
• Secure authentication between outstations and master station, complies with CPNI guidelines
• Diverse comms infrastructure supported – WAN, PSTN/GSM, GPRS, private wire etc.
• Common outstation configuration and application program management from Master stations
• Flexibility – Master or Outstation managed configuration options

What problems does WITS solve ?

• Reduces configuration errors due to machine readable outstation capabilities files – only allows configuration of features and parameters that are actually supported by the outstation
• Version control of outstation configuration and application programs
• Connection management; Callback testing, fallback paths for different media, e.g. Serial, Ethernet, GPRS, PSTN/GSM etc.

What key functionality does WITS provide ?

• Highly configurable outstation generated alarms
  • Flexible limit configuration with optional hysteresis/persistence
  • Choice of actions for each point state (log, event, alarm)
  • Fixed limit values or daily/weekly limit profiles
• Data input features
  • Configurable analogue scaling
  • Stats generation from point data (min/max/min/integral)
  • Standard rate-of-change/no-change detection, state counter and run time calculations
  • Point overrides
  • Dynamically configurable periodic/event logging
• Configuration
  • Standard method of configuring commonly used features
  • Reduces possibility of configuration problems - most errors trapped at point of entry
  • Consistent configuration – outstations will not accept config if any part is rejected
  • Feedback of any rejected configuration – standard error log
