[etherlab-users] datagrams timed out before slave goes to OP

[Peter P]

Hi,
I can connect the slave (EPOS3) to the master and it shows the OP state and the PDO's seem to be properly assigned. However, before there are two datagrams that time out, one of which is the FSM
datagram. What does that mean? Where should I start searching for probable errors in the code?
Besides, if I try to start enabling the slave for RT mode these datagrams will time out the whole time.
Thank you very much for any advice.
