node-red-contrib-siemens-sentron 0.0.1

A node-RED nodes to read electrical measures from Siemens SENTRON series over Modbus TCP/IP

npm install node-red-contrib-siemens-sentron

A node-RED nodes to read electrical measures from Siemens SENTRON series over Modbus TCP/IP.

Node-RED configurator to read Siemens SENTRON series over Modbus TCP/IP


You can install these nodes directly from the "Manage Palette" menu in the Node-RED interface.

Alternatively, run the following command in your Node-RED user directory - typically ~/.node-red on Linux or %HOMEPATH%\.nodered on Windows

    npm install node-red-contrib-siemens-sentron 

How to use

meter node

Use the measure node to configure which information you want to request from the device.

Wire the output of the measure to the input of the Modbus Flex Getter from 'node-red-contrib-modbus' modules.

Enable check box Keep Msg Properties in the Modbus Flex Getter properties.

getter node

Use the getter node to convert the values from the modbus response into human readable numbers.

Wire the second output of the Modbus Flex Getter to the input of the getter.
