for something that's advertised to be an industrial PLC, is questionable. I've programmed PLC's before, and I can't believe how difficult it is to even connect to this device, using a correct programming cable, not enough I/O to run much of anything. Modbus being an industrial standard network, absolutely no documentation on how to connect to it using this software - where to program the IP address or Modbus port number? You should be able to program this PLC through Ethernet or remotely over a Wifi network. I hope there's more to come on this device from Arduino, because right now, for a few more dollars you can buy a Siemens Logo or an IDEC Programmable Relay with expansion modules and all the Industrial functionality you need. I have to give a shout out to Jakob Sagatowski, with his RUclips videos, for doing all the heavy lifting on programming this device.
Hi @automation_jeff, I agree with your comments. Finder, the manufacturer of the OPTA, describes this as a programmable relay only. This is one of the first for the industrial market for Arduino. I am sure that this will improve as the product matures. Documentation, expansion, I/O wiring options, etc. Currently, a Click (Koyo) can be used for several fewer dollars. accautomation.ca/series/click-plc/ Thanks for the comments. Garry
ACC Automation, Thank you for this excellent quick Start guide to using the Arduino Opta. Question: What features set apart the Arduino Opta from other current PLC units in the Market today? I'm familiar with both Allen-Bradley PLC's and Unitronics PLC's. The features this Quick Start guide showed, are similar to the features round in AB and Unitronics PLC's as of today. Why would you recommend people to use the "Arduino Opta" PLC unit?
Hi Agustin, Good question. The quick select guide was only implemented to quickly get users up and running with the software. All of the features were just basic functions. Hardware: Currently, 8 inputs (digital or analog selectable for each input) and 4 relay outputs. Expandability will come in the future. Ethernet and USB are on board as standard. This can then communicate Modbus RTU or TCP. Programming software: It is open-source software when using the Arduino core/libraries through the standard Arduino IDE or Cloud Web Editor. Most students are familiar with this C++ type of coding. Allows Arduino PLC IDE- IEC 61131-3 programming (full set of 5 languages) + no/code fieldbus + Arduino sketch integrated with shared variables. PLC languages are not open source; the IDE is freely downloadable and usable, while each device's PLC Firmware runtime activation comes with every Opta. Others: The Opta is certified as a PLC by CE and UL (c UL us). There are also Arduino IoT Cloud Dashboard Widgets that can be done. Node-RED would no longer be used. Note: I have yet to test this feature. It is a great investment for the money. Regards, Garry
Hi @@ACCautomation, thank you for the awesome video on Opta. I had a question how would we use Node-Red with the Arduino Opta? Do I run the ladder diagram simultaneously with other programs in this device? I mean to use an inductive proximity sensor, quite similar to your application in this video, however, I wish to keep the Arduino Opta not physically connected to any host PC. So, I am thinking about how to setup Node-Red in this case. Would love any references or tutorials to this question.
I've tried your sketch, others and one I wrote myself (same logic as working OpenPLC RPI). I can initialize the OPTA, connect to to and tell it to download code. I get an error "getcrcfromtarget error reading par: 12293", I click OK and it tells me it uploads the code. The code doesn't run, the IDE says "different code" on the bottom and if I reconnect after a reboot, the IDE pops up a warning that the code is different. Running latest PLC IDE. Built similar logic in OpenPLC and tried uploading, same issues. I must be doing something wrong or have a defective Opta.
Great video! Is there a chance you are doing a video on the RS485 connection using ladder logic? I can't find anything that shows me how to use it. I thought it would be straight forward, but there's no real help on it for ladder logic. Thanks!
Hi @AaronMilford, Thank you for the comment. Yes, I plan on doing some videos on the RS485 connection using Modbus RTU as both the master (Client) and slave (Server). I am currently waiting for some answers and additional documentation from Arduino. This has been promised for the end of the month. Regards, Garry

Do you happen to know if I can send serial signals as "input signals" over the USB cable (from my labview software" to the Opta?
Hi @rickbronx8528,
That is not possible over the USB cable. However, you could send information to the Opta server using Labview as a Modbus Client. I have not tried this, but it looks to be doable.
