8.1.9 Error scenarios
The most common errors, faults and possibilies to correct errors can be found in the chapter
4Diagnoscs and fault eliminaon ^ 93
In the following secons, the causes and remedies for the most frequent applicaon errors in
EtherCAT applicaons are described. The state diagram and descripons on the next pages
serve to localize and remove an error.

8.1.9.1 "Pre-Operaonal" EtherCAT state is not achieved
During the start-up of the EtherCAT bus, a check is carried out at the transion from Init to
Pre-Operaonal to determine whether the physical bus conguraon corresponds to the
congured bus conguraon. If theses conguraons are dierent, the master does not enter
the Pre-Operaonal state. Furthermore, the slaves are inialized during the transion from
Init to Pre-Operaonal. If this fails because, for instance, a slave rejects the conguraon, the
master does not enter the Pre-Operaonal state.
