How to read and write data from Siemens PLCs with IoT

The IXrouter supports several industrial protocols to automatically read data from Siemens PLCs. Data can be transmitted to the IXON Cloud to make it available for alarm notifications and visualisation, or analysis/machine learning on external platforms via the API:

Supported protocols for Siemens PLC:

Using Cloud Logging you can configure the data protocol and device address from your IXON Cloud account without any coding whatsoever. Push the configuration settings to the IXrouter and it will automatically read the data and store it on the IXON Cloud. This opens advanced IoT functionality for data logging, alarms and trend analysis. Watch this short (1 minute) explanation video of Cloud Logging.
