Determining the version via the System Manager
The TwinCAT System Manager shows the version of the controller firmware if the master can access the
slave online. Click on the E-Bus Terminal whose controller firmware you want to check (in the example
terminal 2 (EL3204)) and select the tab CoE Online (CAN over EtherCAT).
Note
CoE Online and Offline CoE
Two CoE directories are available:
• online: This is offered in the EtherCAT slave by the controller, if the EtherCAT slave sup-
ports this. This CoE directory can only be displayed if a slave is connected and operational.
• offline: The EtherCAT Slave Information ESI/XML may contain the default content of the
CoE. This CoE directory can only be displayed if it is included in the ESI (e.g. "Beckhoff
EL5xxx.xml").
The Advanced button must be used for switching between the two views.
In Fig. Display of EL3204 firmware version the firmware version of the selected EL3204 is shown as 03 in
CoE entry 0x100A.
Fig.61: Display of EL3204 firmware version
In (A) TwinCAT 2.11 shows that the Online CoE directory is currently displayed. If this is not the case, the
Online directory can be loaded via the Online option in Advanced Settings (B) and double-clicking on
AllObjects.
7.4.3 Updating controller firmware *.efw
Note
CoE directory
The Online CoE directory is managed by the controller and stored in a dedicated EEPROM,
which is generally not changed during a firmware update.
