6.1 Custom Assembly Instances
Each NR60E2 supports two custom assemblies to read data from the unit. Each NR60E2 also supports six
custom assemblies to write configuration data or commands to the unit.
In addition to the custom assemblies, the NR60E2 also implements the Position Sensor Object as defined in
revision 2 of the CIP specification. Explicit messaging can be used to access all of the attributes defined by
the Position Sensor Object. Additional information on the Position Sensor Object can be found in the
CIP
Position Sensor Object section, starting on page 67.
6.1.1 Read Assemblies
Two custom assemblies are available to read data from the NR60E2.

6.1.2 Write Assemblies
Six custom assemblies are available to write data to the NR60E2.

† Restore Factory Defaults does not affect the IP addressing information. Parameter values are restored to RAM. A
separate Save to Flash command is required to save the factory defaults to flash memory.
All controllers that support EtherNet/IP support explicit messaging. When using
explicit messaging, Message Instructions must be added to your program to com-
municate with the NR60E2. Explicit messaging must be used to configure the
device or preset the position value.
Rockwell Automation controllers which are programmed with the RSLogix 500
software only support explicit messaging. A MicroLogix 1100 will be used as an
example in this chapter. In Rockwell Automation systems, RSLogix 500 version
8.0 or above is required to configure Message Instructions to communicate with
an EtherNet/IP device. Message Instructions do not work correctly in version 10 of
RSLogix 500.
