Beckhoff Ethercat running with slave loss

2 posts in this topic

Hello all, I'm new to Beckhoff and running a PLC with EtherCAT I/O slaves. If one of the slaves is disconnected from the network (power loss or network cable broken) the whole PLC freezes, is there a way of configuring ethercat such that it remains (partially) operational, thus showing me the I/O on the unaffected stations.

This is the legacy of EhterCAT but you can define Sync Unit to solve the issue. You should define Sync Unit for each of remote I/Os. In that case, if the power of one of your remote I/Os has been lost the other part of your network and remote I/Os works without problem. The attached image shows the Sync Unit Assignment  .
