Commissioning and configuration
EP9300-0022 30 Version: 2.3
5.4 EtherCAT configuration
The EP9300 is an EtherCAT master with automatic configuration, i.e. all EtherCAT terminals must always be
present when switching on the system. Since the boot-up of the EP9300 generally takes considerably longer
than the start-up of the EtherCAT slave devices, the latter can be operated on the same power supply. With
decentralized EtherCAT slaves, care must be taken that they are switched on earlier or at the same time as
the supply voltage.
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; EP9300-0022
remains in data exchange. The input data of all EtherCAT devices are then 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
EP9300-0022. 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 EP9300-0022. In this case use a CX8093.
EtherCAT devices that don’t exist in the GSDML
Some EtherCAT devices 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 EP9300-0022 and thus
on the EtherCAT master. EtherCAT devices are addressed automatically; with a few exceptions all EtherCAT
devices are equipped with an EtherCAT ASIC, which then has to be entered in the system, i.e. the Profinet
controller. EtherCAT devices without an ASIC are, for example, EL9400, EL9070 and other EL9xxx. You can
identify these EtherCAT devices using the technical data “Message to E-bus”. If there is a “-” here, then this
EtherCAT device does not have to be entered in the Profinet controller.
EtherCAT devices are registered in the direction of the EtherCAT telegram.
