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 for all EC4 Current Monitoring Relay units are available from the
Internet at www.ab.com/networks/eds/index/html. They may also be built
automatically by some configuration tools since all of the information necessary
for an EDS file may be extracted from the EC4 Current Monitoring Relay.

Product Codes

Since the EC4 Current Monitoring Relay is available in a variety of current
ranges, each model supports a parameter set that is slightly different in terms of
min, max, and default values for parameters that are related to motor current.
Therefore, each model uses an EDS file specific to that model. Configuration
tools use “product codes” to identify which EDS file to use for a given device. The
following table summarizes the various product codes.

DeviceNet Objects

The EC4 Current Monitoring Relay supports the following DeviceNet object
classes.

IMPORTANT

DeviceLogix capability is not available when uploading the EDS from
an EC4 Current Monitoring Relay. The EDS file must be obtained from
the internet.
