@NoamM, can you assist? The fact that UniLogic fails to detect the PLC model seem to be related to API failing. -
The i/o board doesn't seems to be unitronics but it is connected to port 2, as I said, configured also like port 1 with RS485, prtkl MODBus, N, 115200, 8,n,1,N. And yes, the controller has the Ethernet expansion port in the right side and I understand that this is for unitronic modules. In this case it is empty, nothing connected there. What can I understand is that the controller communicates whit the driver on RS485. Both coms says the same, RS485 an so for. That's what I also think, this has some security in it. The original idea was to learn or discover how this system works but I guess I'll need to do it from scratch. The port 2 is modbus 485 also but I'll study this aproach by the way when I can check the device again, but the only ethernet port that I saw the last time was in the righ side, commonly used for expansion to other unitronic modules, or daisy chainning some PLC (as long as I know). Thanks for your ideas, If I have success I'l be writing here, cheers! -
This will not cause any problem in terms of shorts or something that can damage the device? Even if the ladder maybe espect the rs485? I ask this but I have the feeling that this will be safe. The only thing, as you say, is to hope last programmer did a burn upload. Also, if the PLC is starting and I put it in stop in info mode, this will stop the PLC but the modbus line in ladder already was scanned as i can understand. How can I prevent the scan, how to turn on the controller in stop mode? or maybe this wont work as I understand. Anyways, If I have the oportunity to move the jumpers in the future I'l be notifyng. Thanks for the help sir!

I'll forward your email onto my sales guy who is in touch with the customer. Thanks Jeff -
Sir, please let me know will future updates allow Telegram bot integration with Unistream PLCs without needing a UCR router? Including a router isn’t always practical in every project, so it would be incredibly helpful if this functionality could be added directly to the PLC for more flexibility. Thanks
