4.1.5 Checking the EtherCAT connection
The following procedure shows how to check the status of the EtherCAT connection.
1. Click the Online menu, and on the menu, click Login to log in to the PLC.
2. After you log in, click
at the top of the toolbar to run the PLC.
3. If EtherCAT connects successfully, the icons beside the devices become green.
In the Devices window, icons can be shown beside devices and modules. These icons are
shown when the configuration is not consistent with the connected modules.
Moreover, icons are sometimes shown even after you confirm that the connection of the
devices and modules is OK. If this happens, log in to the PLC, click Online > Cold reset,
and run the PLC again. Then the icons should disappear. If icons are still displayed,
check the wire connections and power cycle the main power to the EtherCAT slaves.
