The WITS Protocol Standards Association

Ownership and Maintenance of the Standard

The WITS Protocol Standards Association (PSA) provides for the long term maintenance and management of the WITS-DNP3 Protocol Standard. Members are drawn from the utilities industry – both users (mainly water companies) and vendors/manufacturers of telemetry equipment. The PSA has its own independent elected committee drawn from members of both the vendor and user communities.

Mission Statement

The WITS PSA is dedicated to the collaborative development, maintenance and promotion of the WITS-DNP3 protocol for the Utilities industry.

Strategy document

To support the Mission statement the PSA Committee defined the following development and maintenance strategy for the protocol so that only one approved version of the standard exists, hence preventing it from fractioning into multiple unsupported versions though uncoordinated development:

  • Develop a clear development strategy enabling vendors to bring WITS capable devices to market
  • Maintain ongoing development of the protocol aligned to users requests and requirements
  • Develop clear guidelines on WITS DNP3 security aligned to CPNI best practice
  • WITS to have a developing presence in other countries outside the UK
  • The majority of water supply companies and water management organisations to have adopted WITS DNP3 as their first choice industry standard protocol for remote field devices  
  • Maintain a clear definition for users regarding where WITS DNP3 fits into their individual company telemetry strategies
  • Ensure the PSA and committee has the correct membership to allow main strategy objectives to be achieved
