It works well. I have use LAN and WAN brokers (mosquito primarily) and had no major issues. It's worth noting if you need secure comms the NX PLCs do this, NJs don't. You'll need an older version of the library for an NJ, the latest only works on NX. It's well documented and the example program is pretty easy to setup.

Posted 16 Nov 2023 Nice to hear, is it possible with MQTT to create redundant systems like two brokers ? Share this post Link to post Share on other sites

We can interface with multiple brokers though so I don't see why you couldn't do that. Share this post Link to post Share on other sites
Posted 28 Dec 2023 Yes I know. is there also a hot swap function if connection is lost to broker 1 ?. For example there is critical application and the broker always must be available and if there is BSOD for example in broker 1 and it goes down,then we need to carry on broker 2 without any human interference's would that be possible ?
