With the protocol converter for S7-IIoT, data points can be collected easily and conveniently via S7 Ethernet or Modbus TCP. No changes to the existing S7 CPUs are required! As a standalone device, this highly communicative protocol converter does not affect PLC cycle times. Selected data points are made available to higher-level systems via the OPC UA server and MQTT client (Publisher / Subscriber), together with typical functions such as logging. All of this is provided without PC software, as it is included onboard in a WebConfigurator. Exactly as required by RAMI4.0. In addition, the integrated Node-RED can be used to implement hundreds of thousands of additional functions such as SMTP, FTP or tweeting, visualisation, read-aloud functions, etc.
