MarkCG Posted June 29, 2017 Report Share Posted June 29, 2017 Does any one have any experience dealing with ethercat slave connection and disconnection while the system is running? Say you have a daisy chain of etherCAT slaves and the last one gets disconnected. From what I have seen the Scan Engine stops and goes to configuration mode. What if I want the system to just keep running as normal? Quote Link to comment
smithd Posted June 30, 2017 Report Share Posted June 30, 2017 I don't think thats possible. If I remember ecat correctly, in your scenario one of the devices that is forwarding the data packet has been removed, so the packet never returns to the host (http://www.ni.com/white-paper/7299/en/). You'd have to probably rescan modules to update the configuration (so it knows the last device is gone) and then change mode back to active. Supposedly beckhoff claims to have a 'hot connect' feature but I don't think NI has that. Quote Link to comment
