14 MODBUS

14.1 MODBUS for Node-RED

To install the Node-RED package, copy all folders from the node-red-modbus directory to
/usr/lib/node/node-red/node_modules/

Then, restart node red via /etc/init.d/node-red restart

Do not try to install the node-red-contrib-modbus package from within Node-RED.
This will fail and leave you with an inconsistent state.

Use our method to get a working version.

Creating a first flow

14.1.1
