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. The EDS file for the E1 Plus DeviceNet Module is

available from the Internet at www.ab.com/networks/eds/index/html

. It can

also be built automatically by some configuration tools since all of the

information necessary for an EDS file may be extracted from the E1 Plus

DeviceNet Module.
