As requested at the last Plugfest, we will be inviting more users this time around. To facilitate this, the plugfest will be held in the same location and on the day before the WITS User Meeting, thus allowing […]
In late 2015, the membership of the WITS Protocol Standards Association (PSA) suggested that having more visibility of what the Protocol Standards Association Committee (PSAC) is doing would be good. In reply to this request, the Strategy Group of the PSAC did the following:
NI Water Telemetry provides monitoring (and in some cases control) of approximately 4,500 clean and wastewater assets. Telemetry not only provides alarm annunciation, local monitoring and control but also provides regulatory and operational data. There is a reliance on accurate and timely data being provided for business, operational purposes and for the security of customer water and wastewater facilities.
At each asset, signals are marshalled into a local […]
The WITS-PSAC would like to draw members attention to a security notice that has been issued by the DNP User Group.
Last year there was a cyber-attack against the Ukraine Power Grid using malware named as CrashOverride (also named as Industroyer). The attackers spent some time analysing the structure of the Ukrainian SCADA system and then inserted the malware which took over, amongst other items, the protocol […]

There came a point in the development of the WITS-DNP3 protocol, many years ago, when we had to migrate from writing documents about the protocol and thinking about how it would work, to building and testing real devices. To do this we used plugfests. For WITS and many other organisations, a plugfest is a chance to bring various bits of equipment together and test that the interfaces between them all work as expected. In […]
From the inception of the WITS Protocol Standards Association we have recognised the massive contributions made by our Founder Members, and have reflected that in our scale of membership fees. However the Committee has decided that we need to rationalise the fees in order to simplify our accounts and in addition attract new members to the PSA by removing the registration fee for new members.
Therefore from 6th June 2017 the membership […]
Xylem is kindly hosting the #WITSPlugfest event at their Nottingham, England offices.
26 attending engineers, 9 Field Device manufacturers and 2 Master-Station developers.
Lots of very detailed discussions, scanning logs, sharing of information and ideas but most importantly: Testing! By the end of the day we will have improved the quality and reliability of the WITS-DNP3 protocol and learned a great deal about each other’s systems and products.
Plug-Fests are a great way to bring everyone together to […]
