Online/offline list
While working with the TwinCAT System Manager, a distinction has to be made whether the EtherCAT
device is "available", i.e. switched on and linked via EtherCAT and therefore
online
, or whether a
configuration is created
offline
without connected slaves.
In both cases a CoE list as shown in Fig.
“’CoE online’ tab”
is displayed. The connectivity is shown as offline/
online.
• If the slave is offline
◦ The offline list from the ESI file is displayed. In this case modifications are not meaningful or
possible.
◦ The configured status is shown under Identity.
◦ No firmware or hardware version is displayed, since these are features of the physical device.
◦
Offline
is shown in red.

◦ The actual identity is displayed
◦ The firmware and hardware version of the equipment according to the electronic information is
displayed
◦
Online
is shown in green.
