Switching EtherCAT devices on or off during the runtime
If one or more EtherCAT devices should fail during the operating phase, an error response is generated on
the PROFIBUS. The input data of all EtherCAT devices are then invalid and the output data are no longer
accepted. This also applies to the devices that are still in operation on the EK3100. 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 EK3100. In this case, use a CX803x.
EtherCAT topology
All EtherCAT devices must be entered in the order in which they map themselves on the EK3100 and thus
on the EtherCAT master. EtherCAT devices are automatically addressed; with a few exceptions all EtherCAT
Bus Terminals are equipped with an EtherCAT ASIC. 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 need not be taken into account for the mapping.
EtherCAT devices are registered in the direction of the EtherCAT telegram.
