[etherlab-dev] Slave state change from SAFEOP to OP without PDO update

Hello,

I have noticed an issue with the etherlab EtherCAT master. If the slaves a split into two domains (with different update cycles) then the state change SAFEOP->OP can be requested by the master without a slave have received output data. This makes the slave stay in SAFEOP with an error: EtherCAT ERROR 0-19: AL status message 0x001B: "Sync manager watchdog". 

Is this a bug or a missing feature?

Best Regards
Kim Madsen
