I’m guessing that the rs485 port on the Tstat10(wifi) isn’t set up as a subnet of the Tstat10 like it would be on the other controllers.
I have setup a small test system with a Tstat8 connected via rs485. I can start T3000 with a usb-rs485 stick and set it up as modbus or bacnet, and everything connects fine.
I can set up the Tstat10 and configure the wifi, and that connects nicely with T3000 on my network. Then I connect the rs485 port of the Tstat10 to the Tstat8, with the intention of unplugging the usb-rs485 stick, so that now the Tstat8 is only connected thru the rs485 port of the Tstat10. But once I do that and search for nodes, nothing comes up except for the local network connection of the wifi Tstat10.
If I plug the usb-rs485 stick back in to my computer and search on T3000, then it obviously finds the Tstat8 no problem. If I shut off my wifi and try to search for the Tstat10 via rs485, I can’t get that to work no matter whether I configure it for Bacnet or modbus slave or master.
So basically, nothing is really connecting thru the Tstat10 rs485 port. I will do some Wireshark testing to see what’s happening there. Then I plan on clearing the Tstat10 back to factory and without setting up wifi, see whether I can connect to the Tstat10 thru rs485.
Open to any suggestions
