What is the PLC platform and OS Image used? Node-RED needs some other processes running on the machine to work properly. Can you check if e.g. Evok and UnipiTCP run on your PLC?
The best "quick start" is using our ready-to-use OS Images with Node-RED and all necessary tools integrated:
raspberry pi 3 and Original rasbian.
