Communication
EDS files (Electronic Data Sheet) are used for all CIP-based protocols. For the AMS 35x
i
product series, these are the following protocols:
• EtherNet/IP
• DeviceNet
You can find the EDS file at www.leuze.com
The EDS file contains all communication parameters of the participants, as well as the avail
-
able objects. The DeviceNet communication tool reads the EDS files of the participants
present in the network and uses this information to calculate the configuration data that is
subsequently loaded onto the participants.
The input/output data is addressed according to the following fundamental scheme:
1.
Device address (MAC ID)
The participant is addressed with its MAC ID, which is unique in the network.
2.
Object class identifier (class)
Used as the basis for addressing the desired object class.
3.
Object instance identifier (instance)
Addressing of the object instance within the object class.
4.
Attribute identifier (attribute)
Addressing of the attribute within the object instance.
5.
Service code (get, set, reset, start, stop and others...)
The service code ultimately describes the type of access to the data, e.g., reading or
writing.
