While not really directly a node-red question, we are helpful folk here.

Firstly, your statement is contradictory, secondly we'd need more info to assist you.

Can you...

- List out IP address, mask, gateway settings of...
  - Windows PC
  - RPI
  - PLC
  - Router/switch

- Tell us how they are physically connected (a drawing would help)
