Can anyone help me determine what I'm doing wrong here? I want to attach a steel plate to a cable. The cable is continuous from bottom to top however I modeled with nodes in the span in order to apply some rigid links that will be holding up the steel plate. When you have cable-to-cable nodes do i need to add a "connection"? I only have a uniform windload applied in addition to pretension and some dead load (no loads in y direction).
Pdelta calculation must be run.
What else - send us screen capture or model.

zip it before attaching or upload and send link from services www.filemail.com or wetransfer.com
Structure Type should be Frame 3D or Shell.
Ther are only truss bars due to Truss structure type - so they have no rotational dof.
Corrected model attached
Thanks for the assistance Rafal. The model type mistake makes sense, clearly. However I still have not determined the necessary steps to add rotational support to my cable that has been "broken" up into segments. I am not able to get this model to run due to stability issues....help?
Anyone know how to connect a rigid link to cable midspan and make it structurally stable? Do i need to somehow use "Compatible Nodes"? Do I need to segment my cable and then add cable releases? Help please.

I do not think you have read my posts or document about cables in the thread I mentioned.
Errors in your model:
- wrong supports
- missing pdelta

Connected properly in your model. What about replacing rigid bars by rigid links?
Do I need to segment my cable and then
Yes.
add cable releases?
