Fig. 44 Twincat Config Mode Display - Beckhoff EP3356-0022 Documentation

Commissioning/Configuration
• The actual EtherCAT and IO-Link hardware (devices, couplers, drives) must be present and installed.
• The devices/modules must be connected via an EtherCAT cables or an IO-Link cable in the same way
as they are intended to be used later.
• The devices/modules must be connected to the power supply and ready for communication.
• TwinCAT must be in CONFIG mode on the target system.
The online scan process consists of:
• Detecting the EtherCAT device (Ethernet port at the IPC)
• Detecting the connected EtherCAT devices: This step can be performed independent of the previous
step.
• Troubleshooting
The scan with existing configuration can also be carried out for comparison.
Detecting/scanning of the EtherCAT device
The online device search can be used if the TwinCAT system is in Config mode (blue TwinCAT icon or blue
indication in the System Manager).

Online scanning in Config mode
The online search is not available in RUN mode (production operation).
Note the differentiation between TwinCAT programming system and TwinCAT target system. The
TwinCAT icon next to the Windows clock always shows the TwinCAT mode of the local IPC. The
System Manager window shows the TwinCAT state of the target system.
Right-clicking on "I/O Devices" in the configuration tree opens the search dialog.
