Supported Instance Attributes
Table R3.3 on the following two pages lists all of instance attributes implemented by the NR60E2. Table R3.2
below describes the Data Type values used in this table.
Table R3.2 Explanation of Data Types
When programming these instances, always use a Class Code of 16#23.
Data Type Length Description
BOOLEAN 8 bits Holds single on/off (true/false) value
BYTE 8 bits
Holds up to 8 bits of data which should
not be considered to be a scalar value
USINT 8 bits Unsigned 8 bit value
WORD 16 bits
Holds up to 16 bits of data which should
not be considered to be a scalar value
UINT 16 bits Unsigned 16 bit integer value
DINT 32 bits Signed 32 bit integer value
UDINT 32 bits Unsigned 32 bit integer value
Attrib. ID Access Name Data Type Description
16#01 - 1 Get Number of Attributes USINT Number of supported Attributes = 21
16#02 - 2 Get Attribute List
Array of
BYTE
List of supported Attributes = 01, 02, 0A,
0B, 0C …71hex
16#0A - 10 Get Position Value Signed DINT Current position value
16#0B - 11 Get Position Sensor Type WORD


1 to 65,536 counts per turn
16#11 - 17 Set
Total Measurement
Range
UDINT
Counts before roll over to zero.
Single Turn NR60E2
: Range of 0, 2 to
65,536
28 bit Multi-turn NR60E2:
Range of 0, 2 to
268,435,455
30 bit Multi-turn NR60E2:
Range of 0, 2 to
1,073,741,823
16#13 - 19 Set Preset Value DINT
Sets the position to the specified value.
Calculates an internal offset that will be
saved to the non-volatile storage if Save
service (code 16#16) is issued.
16#18 - 24 Get Velocity Value DINT
Current speed. The value is in the format
specified by attribute 16#19
