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?
Hi all, I am designing the control system for what will be a fairly large machine and I considering the ways the overall system can be architected. I have created systems with a cRIO master and a single cRIO 9144 EtherCAT slave. However I have not tried using multiple EtherCAT cRIOs and/or 3rd party EtherCAT devices like servocontrollers. Has anyone used more than one EtherCAT slave with a cRIO? How many slaves can you realistically daisy chain off one of the newer "value" cRIOs like the 9068? I know this answer will depend on number of scanned variables and the scan engine period. At 10ms scan engine period, what can you expect?
I am trying to connect some Beckhoff EtherCAT modules to a cRIO and at the beginning everything was looking good, but now I have some serious troubles with the EtherCAT drivers.
When I am trying to start or deploy a project everything is crashing, cRIO is rebooting, PC to cRIO communication is lost and nothing is working. The problem is with the EtherCAT drivers, because if the EtherCAT drivers are disabled everything is working.
Does anybody has any idea what should I try?
Did somebody managed to use Beckhoff EtherCAT modules with a cRIO and LabVIEW 2009?
Any help or reply is much appreciated.
