Add Targets and Devices
dialog window shown in Figure 14, select
Existing target
or device

Adding the EtherCAT Master
Note
When all the slave devices are discovered, the LabVIEW
Project Explorer
window lists each slave device and any installed C Series modules. If the AKD
EtherCAT drive does not appear in the
Project Explorer
window after this step,
confirm that the NI Scan Engine is in Configuration mode and repeat steps 11 and 12.
Refer to the

Note
The
Scan Period
setting is used to determine the AKD EtherCAT drive
Cycle time and Cycle exp settings, ignoring any values in the
EtherCAT:
Advanced:Initial Commands
dialog box in the LabVIEW Project. These settings
must match for proper communication between the drive and the EtherCAT master.
