Configuration
EK9300

Version: 3.2.6
Switching EtherCAT devices on or off during the runtime
If one or more EtherCAT devices should fail during the operating phase, a plug alarm is sent; the EK9300
remains in data exchange. The input data of all EtherCAT devices are invalid and are set to FALSE or
ZERO; the output data are no longer accepted. This also applies to the devices that are still in operation on
the EK9300. If you wish to use the option to plug in or unplug devices during the runtime, a further “Sync
Unit” must be configured. This is not possible with an EK9300. In this case use a CX8093.
EtherCAT devices that don’t exist in the GSDML
Some EtherCAT Slaves are not included in the GSDML and thus cannot be used (yet). The CX8093 can be
used here, since it supports all EtherCAT devices in principle.
EtherCAT topology
All EtherCAT devices must be entered in the order in which they map themselves on the EK9300 and thus
on the EtherCAT master. EtherCAT devices are addressed automatically; with a few exceptions all EtherCAT
Bus Terminals are equipped with an EtherCAT ASIC, which has to be entered in the system, i.e. the
PROFINET controller. EtherCAT Terminals without an ASIC are, for example, EL9400, EL9070 and other
EL9xxx. You can identify these EtherCAT Terminals using the technical data "Message to E-bus". If there is
a “-” here, this terminal does not have to be entered in the PROFINET controller.
EtherCAT devices are registered in the direction of the EtherCAT telegram.
