What happens if one or more nodes are not present or stop working?

In the event that the fault is located in the first slave, the most common symptom is that the drives_clock flag in the master’s structure becomes false.In the case of fault located in other nodes, it depends on whether they are present during the network startup phase or not:if there are missing nodes in the startup phase the network will not go beyond the INIT state, you can use the SlaveMonitor to see which is the first node that presented an error or is missing.In case the network has already gone into operational, the field network_ok of the master becomes false, you can use the SlaveMonitor to check which slave is missing, or have submitted an error.Attention: if a slave stops working, the other slaves may remain in operating status: it is therefore the task of the application to reset the outputs or take appropriate actions.
