ASERCOM has released Version 1.1.0 of its Modbus Electronic Data Sheet (EDS), providing an updated framework for the standardised description of Modbus server devices and their data models.
The Modbus EDS enables manufacturers to describe device information, communication parameters and individual data points in a machine-readable JSON format. Compatible clients can parse this information automatically, helping to simplify device integration and reduce the need for proprietary data descriptions.
Compared with the previous release, Version 1.1.0 includes several practical enhancements. These include additional baud rates and an InterFrameGap parameter, an additional value definition for digital data, corrections to unit codes and examples, and a new UnitNotation feature for prefixes such as milli, kilo or mega. The update also introduces guidance for automatic device identification using Modbus Function Code 43.
The new Modbus EDS V1.1.0 is available here with immediate effect.
