Arduino Opta Lite [AFX00003] - Compact Industrial IoT Controller with Digital I/O, Analog Inputs, Modbus Support, and Edge Computing for Automation & Control Systems

I have programmed many small PLCs in my time, but this is the worst ever. Inadequate software from arduino and a vastly over engineered connection method. I will stick with Siemens Logo DO NOT buy this OPTA at the moment, perhaps in later years when the interfaces and connection methods are much improved but certainly not at the moment.

La pecca di questo prodotto è il software Arduino PLC IDE, ancora da finire di sviluppare direi. Lato hardware peccato non ci siano i LED abbinati agli ingressi!! Altrimenti 5 stelle ci stavano!

I purchased the Opta Lite with hopes it would be a solid / user friendly product that can be used for small projects and to help teach others who want to use it for basic PLC operation and programming to get beginners into automation. I was unfortunately severly disappointed. There are two IDEs that are used to operate the device from Arduino - Arduino IDE and Arduino PLC IDE. In order to get to where you can actually use the PLC for it's intended purpose by using the typical programming languages to build it's functions, you have to start by connecting to the PLC. This is a significant issue that I have yet to solve. The documentation leaves out important information for setting up communication and does not provide good troubleshooting steps to connect. Without thorough and complete documentation or customer support, this product doesn't do the bare minimum of bringing the customer to the basic setup of its logic. Perhaps this product was released too soon before working out bugs or before adequate documentation could be completed, but either way it was a complete waste of $150 and would serve better as a paperweight. When I tried to reach out to Arduino to get support, the only page that allowed contact info to be filled out would not actually allow me to click on the boxes or fill them out (I tried multiple browsers and even mobile). Support is clearly behind the curve for Arduino. I hope Arduino can solve its issues instead of continuing to market an unusable product.

je le renvoie pour le réseau incompatible avec Modbus et l'incompatibilité logicielle avec Arduino PLC . Cela fait beaucoup mais il est en Lite il parait que c'est normal mais c'est bien trop bridé . Donc très déçu, et je pars sur du Waveshare ESP32 avec modbus TCP-IP

Not good at all. Connection issues like everyone else. Do plenty of research before you purchase. It’s cheaper to but 24v plc clones and relays vs what you’ll spend trying to get this to work.

Nice little package. USB-C and Ethernet connectivity are promising for deployment, but.. the IDE: my god. If they were hoping to get industrial buy-in on this, they really missed the mark. Download Arduino IDE. Install tools for the Opta. Install Opta PLC IDE. Read instructions twice. Watch the software fail to compile/connect repeatedly. Read forums. Execute suggestions. Fail again. I should have a squeaky nose and a water spraying lapel flower after all the hoops I just jumped through trying to make any headway. Two computers. Three versions of their tools.. nada. This’ll be shelved. Maybe I’ll look into it again after a year or two, after they get this sorted, if they haven’t abandoned it. I really wanted this to work. Was looking for a sub-$200 micro plc that didn’t also require some stupid proprietary cable for programming since this is for a DIY home project. Good thing I’ve got some other PLCs laying around the office I guess I’ll use instead. I know they work and will continue to work without any BS.
