Introduction to WITS and the
Protocol Standards Association

Designed By The Utilities For The Utilities

Most utility companies use telemetry to monitor and control their remote assets. Traditionally, telemetry systems consist of “Field Devices” which are linked to a “Master Station” using one or more telemetry protocols and communication methods. Many protocols are proprietary and suffer from vendor lock-in. Other open standards can be difficult to match with the water industries’ particular set of needs. The WITS Protocols are different…[Read more]

Developing the WITS-DNP3 Protocol

The WITS group was formed in 2003 by members drawn from a wide cross section of water companies and water industry suppliers. The team had the aim of helping utilities realise greater efficiencies by encouraging co-operation between water companies and with engineers and consultants in external supplier organisations. The WITS vision was simple:…[Read more]

The WITS-IoT Protocol – Standards based modern telemetry

In 2016 the WITS-PSA began development of a complimentary protocol for telemetry.  The protocol was to be simpler to develop for and test, built using modern industry standards.  The protocol would focus on large installations of smaller devices that were not normally online/connected.  The protocol would incorporate industry standard security mechanisms, ensuring compatibility with stringent national and international critical infrastructure requirements.  The protocol was also to be easily extendable allowing systems to fully plug and play.

In late 2018 the initial version of the protocol was released! [Read more]

The WITS Protocol Standards Association (PSA)

Once the standard was produced, attention turned to its sustainability. To ensure this, the WITS Protocol Standards Association (PSA) was established and currently provides for the maintenance and management of the WITS-DNP3 protocol… [Read more]

Recognition and Supplier Adoption of The Standard

Since the formation of the PSA, work has been carried out to develop field devices that conform to the Standard.  This has been driven by both manufacturers and the utilities… [Read more]
