As you can see appears "undefined" the PBT Principled shader node from blender 2.79, and I need to use it.
Is there a way or other alternative for rendering PBR Textures with all the same input settings that this shader has?

$\begingroup$ It's probably a good one... but what's your reason for not using 2.79? $\endgroup$– Robin Betts ♦Jan 29, 2019 at 21:07

The principled BSDF shader was introduced in version 2.79. Previous versions of blender will not be able to use such node.
You would need to recreate the properties of a Physically Based Shader using a combination of other shader.
There are quite a few "tutorials" out there that show how to do this. Here are some links:
https://www.blenderguru.com/tutorials/pbr-shader-tutorial-pt1?rq=pbr
and
https://meshlogic.github.io/posts/blender/materials/nodes-pbr-basic-shader/
but there are plenty of others you can find using your favorite search engine.
