Hi,
Indeed, some slaves are not in OP state. There are 6 slaves on my network, two of them are in PREOP state. I can get their states using ethercat slaves -v command but when I run ethercat master command, master is in OP state. Can master be considered as OP state if at least one slave is in OP state?

So for each bit that is set you can interpret that as at least one slave was in that state. If there is a state bit set you are not happy with (or expecting) then you will need to interrogate each slave individually to find out which slave(s) are in that state, using ecrt_slave_config_state(). On startup (or comms interruption and recovery) you can expect to see slaves at different stages on the way to OP mode. If you are fully operational and you have a PREOP bit set, then you likely have a device that is not known so is not configured, or has the wrong address so it is not being attached to correctly. If a slave stays in SAFEOP then you probably have a configuration error, check the logs to figure out the problem. Regards, Graeme.

AL states are : * Bit0 : INIT * Bit1 : PREOP * Bit2 : SAFEOP * Bit3 : OP But when I read AL states, states are respetively : * 0x02 (0010) * 0x03 (0011) * 0x0a (1010) * 0x0e (1110) * 0x0a (1010) So, in some cases I don’t know in which state I am ? How can I determine AL State ?
