Modbus in Node-red

Can we install node-red in PC1( IP : 10.10.10.X) and connect to an openPLC which is installed on raspberry PI with IP 10.10.10.Y and send messages using MODBUS TCP/IP protocol ?

Have a look on for what modbus nodes are available.

I couldn't make out much from the library page of openPLC. can you help me how to configure openPLC node in node-red so that I can have a a simple switch and make openPLC turn a LED on/off.
I am trying to build a Simple HMI to turn led on/off.
