Issue Details

  • When I try to set my cRIO-9145 to Safe-Operational Mode, I get the error -214738446 NI Industrial Communications EtherCAT: The Remote target is not responding to EtherCAT RPC. 

Solution

To solve this issue,

  • Make sure the primary Ethernet Port in the Real-Time controller is not connected to the EtherCAT Slave. The primary port is not supported for EtherCAT communication.
  • If you are not using the primary Ethernet port, right-click the EtherCAT master item and select Undeploy.
  • Deploy the EtherCAT configuration.
  • In the LabVIEW Project, right-click your EtherCAT master and select Deploy All.
