# node-red-contrib-redlink

There's an explanation for this node but I really don't understand how it's used, how it communicates, how it sends tasks to other processes to be executed, has anybody used it or knows about it,

At present, my process only listens to other ports according to the output information and can display some store information, but it doesn't seem to be useful.

You should pose this question to the author on the [github page](https://github.com/Gippsman2017/node-red-contrib-redlink)
