NI-9881 CANopen Module is supported by NI-Industrial Communications for CANopen
For information about supported hardware and compatibility with NI-RIO, you should refer to the NI-Industrial Communications for CANopen readme file. There, you will find that NI-9881 requires the following:
- CompactRIO - NI-RIO 4.1 and LabVIEW 2011 SP1 (32-bit) or later required.
- Real-Time Controller: NI cRIO-9012, NI cRIO-9014, NI cRIO-9022, NI cRIO-9023, NI cRIO-9024, NI cRIO-9025, NI cRIO 906x, NI cRIO 903x, NI cRIO 908x
- CompactRIO Reconfigurable Chassis: NI cRIO-9111, NI cRIO-9112, NI cRIO-9113, NI cRIO-9114, cRIO-9116, and cRIO-9118
- LabVIEW 2011 SP1 FPGA Module or later
Thus, NI-9881 is not supported when used in cRIO-910x or cRIO-907x reconfigurable chassis but only in cRIO-911x chassis or in cRIO-903x, 904x, 905x, 906x and 908x integrated controllers.
