IDEC has released a firmware upgrade that enables MQTT protocol support in its MicroSmart FC6A Plus line of PLCs. The IIoT protocol is supported on Ethernet port 1, so the FC6A can use existing wired, Wi-Fi, or mobile data wireless networking to connect with on-site or cloud-based brokers. No additional hardware is needed. Users can take advantage of the traditional PLC control logic and I/O functionality, or they can use the FC6A as an IIoT data concentrator for many other PLCs and intelligent devices. The FC6A with MQTT supports Amazon Web Services AWS IoT Core today, with future support planned for Microsoft Azure and Google Cloud.
