Arduino unveils the Opta – “Micro PLC” for industrial IoT
I do a <i>lot</i> of PLC work.<p>The Arduino IDE is totally unsuitable for it. No idea what they are doing about this.  It would take an amazing amount of work to fix this.<p>As for PLC functionality people actually use, the product page says &quot;Optional support for standard IEC 61131-3 PLC languages&quot;. This is what folks use for real. I presume this means &quot;we didn&#x27;t want to pay CodeSys but you can&quot;. Or something.
That sucks.<p>Maybe they are relying on MBed support as their basic realtime story but, as mentioned, their dev environment is unsuitable for this kind of work.<p>There is no mention of expected scan time for ladders or guaranteed latency for anything else<p>So for the intended market, this doesn&#x27;t look interesting so far. It seems like it will go the way of the x8 and land with a huge thud.<p>For a random person wanting an Arduino in a cabinet on a din rail, I can see maybe they&#x27;d use it.
