3.3 EDS file
An Electronic Data Sheet is an external disk that contains information
about configurable attributes for devices, including the object addresses of
each parameter. The following figure shows that the configuration tool uses the
EDS file to configure those Modbus RTU devices. The application objects in
these devices represent the destination addresses for the configuration data.
These addresses are encoded in the EDS. ICP DAS provides users with
DNS_MRU Utility software to create the suitable EDS file. The EDS file system
architecture is as figure 3-8.

EDS provides information about the device’s configuration data in terms of the
following:
context

The information in an EDS allows configuration tools to provide informative
screens that guide a user through the steps necessary to configure a device.
ICP DAS provides CAN utilities, so that users can setup their own EDS file.
You can use the EDS file in the DeviceNet Master to access DeviceNet Slave
devices. The DNS_MRU Utility is a very powerful tool for the DeviceNet
network. It provides DeviceNet Slave information and supports the graph
interface for users to make up the EDS file of their own system. For more detail
information on this topic, please refer to the next session.
