Status of the IREDES specific part of the OPC UA companion specification mining

In January and February 2022 we continued our work on the OPC UA companion specification mining together with the German Machine Builders Association (VDMA), The intention was to have it ready for the BAUMA 2022 which took place in Munich from 24th to 30th October. Unfortunately, due to lack of resources at VDMA, this had to be postponed. On 15 March, we had a meeting with the VDMA to discuss the collaboration process of last year. Since then, external OPC/UA specialists are involved and we have just finished incorporating all the changes into the draft that were requested after review of the OPC//UA specialists. As there also are changes needed in the IREDES nomenclature, later we will come back with proposals to our IREDES members on how to incorporate them into coming versions of IREDES. This will assure that the IREDES content is covered by OPC/UA and OPC/UA is a transparent carrier for IREDES defined content.

New IREDES members in 2022

In 2022 we Were joined by 2 members both of whom we will introduce in this article. The sequence in which they are mentioned is alphabetically ordered.

Orica: Orica is one of the world’s leading mining and infrastructure solutions providers. From the production and supply of explosives, blasting systems, mining chemicals and geological monitoring to their cutting-edge digital solutions and comprehensive range of services they sustainably mobilize the earth’s resources.

XSite Machine Control Systems: XSite Machine Control Systems is a Finnish German company mainly produces control systems for mobile earthmoving machines, as well as site management products.

New LHD/Truck Equipment profile including GMG timing

The updated LHD/truck equipment profile now includes a slightly adapted version of the GMG operational timing model, which was initially developed for open pit mining. The generic part of the model is implemented as an extension of our generic Production Performance reporting type.

The LHD specific part is implemented in a new Production Performance type which inherits from the new generic Performance reporting type and includes all functionalities of the current Performance reporting type. For details, see the working documents accessible in the member area at

Now we would like you to evaluate and comment on the new reporting type. It will be open for revision and commenting until 24July 2023. Please send comments directly to ccibis@iredes-org.
