6.2.6.
EtherNet/IP
The relay supports communication using EtherNet/IP protocol
which is a part of CIP (Common Industrial Protocol) family.
EtherNet/IP protocol is available with the optional inbuilt
Ethernet port. The protocol can be used to read / write data
from the relay using request / response communication or via
cyclic messages transporting data assigned to assemblies (sets
of data).
EtherNet/IP main features:
Static data model: 2 standard objects (Overload and Control
Supervisor), 2 private objects (one for digital data and one
for analog data) and 4 configuration objects for protection
functions configuration
Two configurable assemblies (one producing and one
consuming) with the maximum capacity of 128 bytes each
EDS file that can be fed to any client supporting EDS files:
can be generated at any time, all changes to EtherNet/IP
configuration (see configuration parameters in table below)
or to assemblies‟ content require generating of the new EDS
file.
Three types of communications are supported: UCMM (one
time request / response), Class 3 connection (cyclic request /
response) and Class 1 connection (cyclic IO messages
containing assemblies‟ data)
EtherNet/IP implementation on VAMP relay serves as a server
and is not capable of initiating communication.
