Clear errors and switch to operational mode in EtherCAT Industrial Communications

[O.Alahmad]

Hi all,

I am using an NI 9045 CompactRio to communicate with a motor drive via EtherCAT.

Is there a way (not using SoftMotion) to clear device errors (if there are any) and then switch to operational mode programatically?

I am currently doing that using the Online Slave Device State window (see image). Are there any VIs or such that I can use to perform this task?

Regards,

Omar

Hey O.Alahmad,

There are Clear Errors.vi you can use to clean the device errors in your code. However, NI-EtherCAT doesn't support switching to operational mode programmatically.

Hey O.Alahmad,

NI provides Invoke Node which can apply to switch the slave mode in the program.

Hi zhengchen,

Yes! That did the trick. It completely passed my mind that I can use an invoke node. Thanks!
