Error Light double flash



We have set up 2 bytes in and 2 bytes out (status and control words) when we download the configuration the run light is on but the error is giving 2 flashes. A nodeguard event or a heartbeat event has occurred. I have looked in the drive and can see the 500ms heartbeat signal, if the time for this is changed it also changes in the drive. Is there any way I can confirm it is a node guarding causing the issue and not a heartbeat issue



Hello Cole,

What device are you working with is this the CM CANOpen module?
