How can I read the strain value from binout using SCL of LSPP?

I would like to automate post-processing using the SCL in LS-PrePost.
The processes I want to automate are as follows.

　・Read binout(elout) and get the 1st principle strain of the middle layer of the SHELL element (d3plot is too heavy).
　Find the 1st principle strain that is the largest through all steps and get the time and Shell id of that step.

I have looked at the SCL documentation, but I couldn't code it well enough to my ability.
I wish I could at least find an example of an SCL that reads binout.
