NI 9881 on cRIO 9035, missing bus power for transreciever?

[kkaustubh]

Hello,

When i am running a motor control VI utilizing NI 9881 with cRIO 9035, labview is shooting an error: 0x80054B65 relating unavailability of bus power, however on chassis, the module 9881 has green LED1 blinking. As per my understanding the NI9881 is internally powered. So why the error?

Also in NI MAX, NI 9881 is not displayed under Interface and Devices under cRIO 9035,

as shown in attachement

How to properly configure the NI-9881?

*correction: NI 9881 manual mentions external power. I will connect this and check on this.

i am also using the same modules , but i can not find the CANopen1 port in the MAX when the FPGA is continuously  running. Maybe you can give me more advice.
