Tension-only spring in Simscape Multibody

Hello,

I need to make tension-only springs in Simscape Multibody. I found a lookup table-based spring here https://www.mathworks.com/matlabcentral/fileexchange/25238-simscape-language--nonlinear-spring but its ports are "C" and "R" and I can't seem to hook them up to my "B" and "F" ports. That turns out to be a hard thing to google.

Can I use that file to produce tension-only springs in multibody? If so, how do I connect them into my systems? If not, what should I use?

Thank you.
