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?

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:
but there are plenty of others you can find using your favorite search engine.
