Commissioning/Configuration
Detecting/Scanning the EtherCAT devices
Online scan functionality
During a scan the master queries the identity information of the EtherCAT device from the device
EEPROM. The name and revision are used for determining the type. The respective devices are lo-
cated in the stored ESI data and integrated in the configuration tree in the default state defined
there.
If an EtherCAT device was created in the configuration (manually or through a scan), the I/O field can be
scanned for devices/slaves.

The configuration was established and switched directly to the online state (operational). The EtherCAT
system should be in a cyclic operational state, as shown in the following illustration.
Fig. 49: online display example
Please note:
• All Boxes should be in OP state
• "frames/sec" should match the cycle time taking into account the sent number of frames
• no excessive "LostFrames" or CRC errors should occur
The configuration is now complete. It can be modified as described under manual procedure.
