Version: 2.5

Fig. 14:

"CoE Online

" tab

The figure above shows the CoE objects available in device "EL2502", ranging from 0x1000 to 0x1600. The
subindices for 0x1018 are expanded.

Data management and function "NoCoeStorage"

Some parameters, particularly the setting parameters of the slave, are configurable and writeable. This can
be done in write or read mode

• via the System Manager (Fig.

"CoE Online " tab

) by clicking

This is useful for commissioning of the system/slaves. Click on the row of the index to be
parameterised and enter a value in the "SetValue" dialog.

• from the control system/PLC via ADS, e.g. through blocks from the TcEtherCAT.lib library

This is recommended for modifications while the system is running or if no System Manager or
operating staff are available.
