A breakthrough in developing WITS certified Field Devices
The Committee recognises that, to date, developing and testing a WITS Field Device for self-certification has sometimes proved difficult and costly due to the lack of suitable Master Station test software.
We are delighted to announce that two of our Master Station vendors – Servelec Systems and Schneider Electric – now offer development / test Master Station licences to WITS third party Field Device manufacturers.
Using a verified Master Station […]
Vendors may wish to make amendments/enhancements to their WITS certified products post certification. It is recognised that we need to provide a method for vendors to update their certification details and these changes need to be noted in the Device Catalogue without necessarily going through a full re-certification.
We already state in the Device catalogue: “Note that this Device Profile shows the device’s functionality at the time it was listed as a Self Certified/Verified device. The […]
The WITS Roadmap which records all the versions of the Protocol and Technical Bulletins has been updated.
Also the Technical Bulletins Index has been updated to include the new TB51.
Both have both been published on the website.
It has been observed that several Field Device vendors have misinterpreted the Application Notes regarding the use of Incremental Configuration to configure a Field Device with a mix of static limit thresholds and profiles on analogue and counter points. Technical Bulletin 51 clarifies this issue and contains amendments to the Test Specification to check for incorrect behaviour.
Members can find it now on the website in the Member’s Library.
Errors in the PSA Test Specification have been identified in 3 specific tests. TB49 which covers corrections to these errors has just been published by the WITS Technical Committee.
Find it now on the website at WITS Technical Bulletin #49.3
The WITS Road Map which records all the versions of the Protocol and Technical Bulletins has been updated to include the new TBs which are either currently in hand or have been published.
Find it now on the website at https://www.witsprotocol.org/wits-roadmap/
TB50 which covers Tests for devices supporting multiple versions of the Protocol has just been published by the WITS Technical Committee.
Find it now on the website here: WITS Technical Bulletin #50.2

ABB’s AquaMaster 3 Flow Meter was already WITS Self Certified since June this year. Now ABB have gone one step further and, in conjunction with Schneider Electric and Servelec, have achieved full verification.
The defined verification procedure was followed – see “How to achieve self certified and verified status” for further details.
The device now appears in the Verified Field Devices section of the Device Catalogue.
Metasphere have released the WITS DNP3 MM-IM, an approved self-certified mains powered RTU. Featuring an IEC 61131 programming environment, the WITS DNP3 MM-IM acts as a gateway to expandable IO utilising industry standard protocols including Modbus and Ethernet IP; an RTU and PLC in one box.
With support for over 7000 points and storage for approximately 7.5 million DNP3 events the MM-IM can […]
