Which Modbus node have you installed? node-red-contrib-.....?

What version of Node-RED and nodejs are you running ( both listed when you startup Node-RED)

What is running on 192.168.0.150?

#3

Node-REd version - 0.18.7

node-red-contrib-modbus@2.3.2-r0

There is PC iwth Modscan installed having 192.168.0.150, I am nt sure if I can communicate this node with Modscan software?
