Bus continues in state safe_operational after a slave state changes to invalid during setup

Occured with Sensor Actor Unit 7a sho2 left.

The sensor motor board returned ethercat state 18 during pre_operational. soem_conversions only allow 0, 1, 2, 3, 4 or 8 as valid values. After the slave changed its state to invalid, the bus state was changed to safe_operational and the execution continued. This results into working counter mismatches in the following 200 iterations. After that the error "Could not transition into 'operational' EtherCAT state after 200 iterations" occurred and the unit shut down.

The console output lagged during execution. The [realtime loop] messages were displayed after the unit shut down.
