SunSpec Modbus Work Group
The SunSpec Modbus Work Group will work on updates to the SunSpec Modbus specifications as outlined in the draft specifications that are currently available for review at https://sunspec.org/new-tec
David Erhart of STEM
The work group scope is to enhance and develop the SunSpec Modbus interface in each of the functional areas it serves. As we restart this workgroup, we will focus on the following areas:
- Understanding the new SunSpec information models that support the IEEE 1547 interface for Distributed Energy Resources
- How to migrate from SunSpec 100 series models to the new 700 series DER 700 models
- Understanding the new SunSpec information modeling technique
- Reviewing and refining the current specification (currently TEST status)
This Work Group meets via GoToMeeting each week.
SunSpec Modbus was officially named in the IEEE 1547-2018 standard as an approved standard interface. Due to functional changes in IEEE 1547, additional SunSpec Modbus information models and data points were required. The current work group effort seeks to ratify the changes made to the SunSpec Modbus models and educate the community how to use these models in practice.
