Overview of WITS and the PSA.

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 the manufacturers and the utilities.

WITS compliant field devices and master stations are available from an increasing number of suppliers. They are all listed on the Device catalogue on the website.

The range of devices does not only include telemetry outstations, but also specialised devices such as pumping station managers, […]

The WITS Protocol Standards Association

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. The PSA has ownership of the Standard and also the responsibility to ensure it continues to meet the requirements of the utilities industry.

It now has over 80 members mainly from the UK but also with a growing number from overseas. Our […]

The development of the WITS-DNP3 protocol standard

The Worldwide Industrial Telemetry Standards (WITS) group was formed in 2003 with the aim of helping utility companies to become more efficient by encouraging co-operation between utilities and with engineers and consultants in external supplier organisations. The original WITS vision was simple:

“To harness the combined strengths of knowledge, skills and influence of the water industry through taking responsibility for the continuous improvement of telemetry technology and service, through shared developments on behalf of the […]

The need for a Standard Protocol

All Utilities use telemetry to monitor and control their remote assets. Traditionally, telemetry consists of a “Field Device” which is linked to a “Master Station” using a variety of telemetry protocols and communication methods. This provides data and information for the purpose of monitoring and controlling the process and the associated plant.

Increasingly, utilities are placing more reliance on telemetry to provide the required data both to improve their operational efficiency and customer service.

So there […]
