ote: N Process data is sent to the drive independently from the NetRef and NetCtrl bits settings.
Byte 1 of the 101 Output assembly selects which Process Data out selection is read back to the EIP scanner. Bytes 4
through 7 of the 101 Output assembly are application specific.
Select the Multi-purpose application to read data other than what is set as default Process Data.
Default Fieldbus data out selections 1 through 8 are:
1 = Output frequency (hertz)
2 = Motor Speed (rpms)
3 = Motor Current (amps)
4 = Motor Torque (% of nominal motor torque)
5 = Motor Power (% of nominal motor power)
6 = Motor Voltage (Calculated motor voltage)
7 = DC Bus Voltage
8 = Active Fault Code
Multipurpose has a “Fieldbus” group where you reference the FBProcessDataOUT1
through FBProcessDataOUT8 selections. Referring to the 101/107 I/O assembly sheet, bits
PDSELx0–PDSELx3 in each “nibble” of Byte 1 of Output Assembly 101 are used to select
which FBProcessDataOUT (1–8) you “read” back to your PLC. That is integer 1 through 8
converted to binary Bit 0 through Bit 3. Any parameter or monitored value can be read using
the Multi-purpose application, as long as it references a specific ID number. Whichever
ProcessDataOutput selector used from 1 through 8 dictates what bits are used in Byte 1 of
the output assembly 101. Values are then sent via Input Assembly 107 in Bytes 4 and 5 and
Bytes 6 and 7 respectively. If all PDSELxx values are zero, the “Drive state” will be selected
at Byte1 location of 107 assembly.
Speed Reference commands for Instances 20, 21, 23, 25 and 101 are set up to send the
RPM value. This value is sent based off the Motor Nameplate setting provided in the drive.
This would be the direct RPM value written.
