Electronic Data Sheet (EDS)
On EtherNet/IP, the characteristics of a device is stored in an ASCII data file with the suffix EDS. This file is used by configuration tools etc. when setting up the network configuration. HMS Networks supplies a standard (generic) EDS file, which corresponds to the default settings in the module. However, due to the flexible nature of the Anybus CompactCom concept, it is possible to alter the behavior of the product in ways which invalidate the generic EDS file. In such case, a custom EDS file needs to be created, which in turn invalidates the default identity information and require re-certification of the product.
Since the module implements the Parameter Object, it is possible for configuration tools such as RSNetWorx to automatically generate a suitable EDS-file. Note that this functionality requires that the command Get_Instance_Number_By_Order (Application Data Object, FEh) has been implemented in the host application.

Important
HMS Industrial Networks approves use of the standard EDS-file only under the condition that it matches the actual implementation and that the identity information remains unchanged.
