Fig.51: Startup list in the TwinCAT System Manager
The Startup list may already contain values that were configured by the System Manager based on the ESI
specifications. Additional application-specific entries can be created.
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.
