Special Features of Ethernet/IP:
To access the parameter data via Ethernet/IP, an object (also known as a class), an instance and an at-
tribute must be specified in the object-based “Common Industrial Protocol” (CIP).
The 0xA2 object can be used to read—and write, depending on access rights—all parameter data with the
following services:
•
0x0E: Get_Attribute_Single
•
0x10: Set_Attribute_Single
The instance corresponds to the offset from the parameter data table.
Attribute 5 causes the values of the parameter data to be read or, if permission is granted, written as
well.
In addition to attribute 5, the following additional attributes can be queried in object A2h per instance (=
parameter index):
