Issue Details

My Verstand Real-Time Target boots with following error.

System error encountered.
Error Code: 1556
Error Message: LabVIEW: (Hex 0x614 The reference is invalid. This error might occur because the reference has been deleted.

What do I need to do to fix this error?


Error 1556 shows up on the console for a Real-Time target running VeriStand during system boot up if there is not a system definition file deployed.  The error can be safely ignored and will go away when a system definition file is deployed onto the VeriStand target.
This can occur if your version of VeriStand is not the same as your LabVIEW, you can check the compatibility on our website. Please refer to related link.
