Start to make IIoT simple by collecting datapoints easily and comfortable by S7-Ethernet (no changes neccessary at your running S7-CPUs!) or by Modbus-TCP. Collect up to 2.000 data pointsfrom up to 100 partner devices every 100ms (!) As self contained device this communicative gateway does not influence your PLC cycle time. Datapoints are logged and provided to OPC UA-clients and all are configured without PC-software because of the integtrated WebConfigurator as required from the reference model for machines for “industry 4.0”.
And, by the way the integrated Node-RED offers additional functions like MQTT, SMTP, FTP or twittering, visualising, reading etc. by its own nodes.
