Arrived as described, when described.For the uninitiated there's a learning curve, but that's to be expected with new industrial hardware.

El equipo presenta errores, no está aún del todo optimizado el PLC ide que es la interfaz de configuración.No he podido conectarlo por un error muy básico en procesadores, sin embargo al no haber documentación suficiente no se puede corregir por cuenta propia. Procederé a la devolucion

The hardware specs are pretty good for the price. Unfortunately, the software makes this PLC virtually unusable. Just getting the software installed was a pain. The installer exited, issuing a vague error message. I had to enable MSI logging to find out what the problem was. After finally installing, the software wouldn’t start. Again, a nonsensical error message provided no help whatsoever. This time the problem was that the software is just unusable if accessed from a different user account to the one that installed it.I could forgive all of the above, given that the product is fairly new, but it gets worse. Once you’ve finally managed to install and start the software, setting up the controller is excruciatingly painful. You can’t connect to it over Ethernet. They decided to remove that feature in a recent software update. So you need to connect over USB. Then, you need to go through this one-time setup for which there is absolutely no guidance built into the software. Then you need to guess the COM port from a list every time you connect.Okay, now that you’ve finally connected to the damn thing, the typical next step is to assign an IP address to the Ethernet adapter. In most software, this is just a text box that you need to complete. For the Opta, you need to do some searching to find a source file that you need to modify.Programming the controller is mostly fine, except that compiling the program is unbelievably slow even for tiny programs. You’ll also find that you need to frequently reboot the controller. I’ve also had the controller crash multiple times when running a trivial program, requiring a reboot each time. I wouldn’t trust this thing to do anything reliably.Finally, I tried connecting to it over Modbus TCP. This works, but it is horrendously slow. Reading/writing single boolean variables can take up to 50ms! This is frankly just unacceptable. For comparison, every other PLC that I’ve ever tested takes less than 3ms, and is typically around 1ms. This isn’t a hardware limitation. This is just a dreadful software implementation of the most simple industrial protocol that exists.To anyone considering this, I’d highly recommend that you look elsewhere. It’s not even good for learning/education since it works quite differently from everything else. A cheap Raspberry Pi running CODESYS is vastly superior to this hunk of junk. You can also pickup a Schneider M221 for a similar price, which is a much better platform for learning and has free programming software that is easy to use and actually works.

Llego mucho antes de lo esperado, en optimas condiciones, recomendables.

Horrible
