Chapter E DeviceNet Information
Electronic Data Sheets
Electronic Data Sheet (EDS) files are specially formatted ASCII files that provide
all of the information necessary for a configuration tool (e.g., RSNetWorx for
DeviceNet) to access and alter the parameters of a device. The EDS file contains
all the parameter information of a device: number of parameters, groupings,
parameter name, min, max, and default values, units, data format and scaling.
EDS files are available from the Internet at www.ab.com/networks/eds/index/
html. They can also be built automatically by some configuration tools since all of
the information necessary for an EDS file can be extracted from the 825-P
Modular Protection System.
Product Codes
Configuration tools use product codes to identify which EDS file to use for a
given device. The 825-P Modular Protection System has a product code of
100(64 hex).
DeviceNet Objects
The 825-P Modular Protection System supports the following DeviceNet object
