Read or write data to Elmo twitter via Ethercat

[wolfzzx]

the project of my systemthe program

Dear All,
 
       Now, I use NI Crio 9040 communicated with Elmo Twitter via EtherCAT. I have build a set system of CompactRio9040 and elmo driver with labview, some i/o ports can be show in labview via ethercat. When I write or read data from Inputs and outputs port, the drive does not responds to it.

I want to know how to use these Inputs and Outputs ports.

Could you help me?
I am very grateful to you for your help.
 
      Best regards,
