Writing tags to Allen Bradley Micrologix 1400

Hello Guys, I'm a beginner in the subject and I'm trying to write a simple variable in rockwell 1400.
Unsuccessful for now, I'm a ladder programmer and I'm starting on node red now.

could someone give me some reference for this beginning?

I am using the node-red-contrib-pccc


Excuse me sirs,

I solved it only with connecting the lines, like the figure below.
