I am trying to create a simple HMI (human machine interface) to turn a LED on/off using node-red on openPLC ( openPLC is installed on Raspberry PI) . I am new to this entire PLC and not able to get any tutorial as to how to build a HMI using node-red. any help is appreciated.

This is not related to the above conversation.  
Can we install node-red in PC1 and connect to an openPLC which is installed on raspberry PI with IP and send messages using MODBUS TCP/IP protocol ?

Can you please help me out here. I went through the link [https://flows.nodered.org/?term=modbus&num\_pages=1](https://flows.nodered.org/?term=modbus&num_pages=1) to check for configuring openPLC node and other input nodes but dint find anything useful.
