4.6 EDS Data Formats (continued)
4.6.3 Output Data Format
Output data registers are typically not used with the NR60E2. Writes to the NR60E2 should be through Mes-
sage Instructions. Reference chapters contain the information on using Message Instructions to write data to
the NR60E2.
4.6.4 Configuration Data Format
Using an EDS file to add an NR60E2 to your project results in the creation of Configuration tags for the
device. The advantage of this approach is that the configuration data is written down to the NR60E2 when-
ever it connects to the network. If you ever have to swap out the encoder, the new NR60E2 will be configured
with the correct data as soon as it connects to the network. The disadvantage of this approach is that the Con-
figuration data must be valid before the NR60E2 will connect to the network.
Configuration data format is shown below.
Table T4.1 EDS Configuration Data Format
The NR60E2 must have valid data in its Configuration Registers before it will connect to
the network. This is true even if you have saved a valid configuration to the flash memory
of the NR60E2.
Parameter Size Description
Direction Counting
Toggle
Boolean
“0” = Clockwise increasing counts looking at shaft.
“1” = Counter-Clockwise increasing counts looking at shaft.
Scaling Function
Control
Boolean
“0” = Disable Scaling Function. The full resolution of 65,536
counts per turn is used for the Measuring Units per Span.
“1” = Enable Scaling Function. The number of counts per turn
is set by the Measuring Units of Span parameter below.
Counts per Turn
(Measuring Units
per Span)
Double Integer
Sets the number of counts generated over a single turn if the
Scaling Function Control parameter equals “1”. Always sets the
number of pulses per turn reported in velocity data. This value
ranges from 1 to 65,536 and must be set even when the Scaling
Function Control value equals zero.
Total Measurement
Range
Double Integer
Sets the number of counts before returning to zero. This value is
used regardless of the state of the Scaling Function Control
parameter. Parameter ranges:

Single Turn NR60E2
: Range of 0, 2 to 65,536

28 bit Multi-turn NR60E2:
Range of 0, 2 to 268,435,456

30 bit Multi-turn NR60E2:
Range of 0, 2 to 1,073,741,824
Velocity Format Integer
Format of the velocity data. 0x1F04 (7,940) for pulses/second,
0x1F05 (7,941) for pulses/millisecond, 0x1F07 (7,943) for
pulses/minute or 0x1F0F (7,951) for revolutions/minute.
