getting an error event instead of a response event

[bringingkatigbak]

Short version is that I am trying to create a client (master) to read holding registers on a server (slave) via modbus. I am getting the following error event: Error: connect ECONNREFUSED
at errnoException (net.js:776:11)
at Object.afterConnect as oncomplete.

Long version is here:

any guidance would be appreciated, I am kind of new to this area of development.

I am the beginner on Node.js. May I have a complete example of the modbus master (client)?
