Hello,

I am receiving data from my devices in a specific port/ip. However, based on device, I want to send specific message back to the device.

Any help will be hugely appreciated.

Thanks And Regards,  
Rupak Banerjee.

You can use "tcp in", "tcp out" and "tcp request" nodes. You can set specfic IP:port and role as client or server.
