On Tuesday 9th October 2018 at the Green Park Conference centre in Reading, WITS held another WITS-DNP3 Protocol plugfest. The event was kindly hosted by Russ Wheadon of Thames Water. This plugfest built on the success of the January 2018 plugfest which was hosted by Jerry Trowbridge of Northumbrian Water; you can read more on that plugfest here. In a similar way to the January meeting, a WITS User Meeting was planned for Wednesday 10th October, the day after, allowing users to attend both meetings easily. User attendees at the plugfest included Anglian Water, Northern Ireland Water, Northumbrian Water, Severn Trent Water, Thames Water and United Utilities. In all, over 40 people (users and vendors) attended the plugfest day.
At eight o’clock on Tuesday morning, Master Station and Field Device vendors started arriving at the Green Park Conference Centre to set up their equipment. As you can see from the photo above, we had a large room with a circle of tables. Master Stations and Field Devices, along with their support equipment, were set up on those tables and connected together using an internal IP network. GPRS and 3G connectivity was provided by a cellular router connected to the same internal network and we also had PSTN equipment available. The day drew to a conclusion at around five o’clock.
The day was split up (informally) as follows:
- A connection session first thing in the morning to prove that the devices could be connected to the Master Stations.
- For the remainder of the day Field Device vendors were free to test their Field Devices against the Master Stations.
- During the day, a demonstration of WITS-IoT was finalised and then presented, along with some important news about WITS-IoT; see below for more on that.
- Wireless Innovation demonstrated the use of WITS-DNP3 across a satellite link; see below for more details.
- Thames Water, together with Bilfinger, provided a rolling demonstration during the day of how they use and configure WITS devices on their Master Station and the type of applications support they provide internally for doing that.
Apart from vendors testing specific issues with the Master Stations and trying out newly implemented WITS features against the Master Stations, we also suggested that vendors try running a series of regression tests to see if this could be performed during the day and form part of the output of the plugfests.
One very promising addition to the normal plugfest regime was the inclusion of new vendors as invitees to the day. A couple of vendors who have recently joined WITS, Hydro International and Detectronics, both attended the day so that they could get a better idea of what was involved in the development of WITS Field Devices.
Who came and what were they testing
The following table lists the FD (Field Device) vendors who attended the day. As well as these FD vendors, both Master Station vendors also attended: Servelec Technologies with Scope (version 4.6, trunk revision 62232, expected to become the Quality Street release), capable of supporting up to WITS 1.2 and Schneider Electric with ClearSCADA 2017 r3 Beta 6.80.6834, capable of supporting up to WITS 3.0.
