Yup; here thinking along the lines of adding a KNX module to the OPII.
I am thinking then the KNX OmniPro module with it's web interface lets you talk to the modbus devices. That said then you can define a KNX device as a thermostat or a temperature sensor.
You would leave your thermostats in place (and not need the OmniStats) and you could maybe manage them via the OmniPro 2 panel/KNX. Just a guess here.
Connecting Modbus to KNX
You have two devices in two different buildings on two completely different networks, one that uses the Modbus RTU protocol to communicate, while the other one talks KNX protocol and they need to talk to each other. What do you do?
A FieldServer is a protocol converter or gateway that can communicate in many different protocols and physical layers including Modbus RTU protocol and the KNX protocol. The Fieldserver acts as a middle man between the two devices. It reads data from one device, stores it internally and makes it available to the 2nd device using another protocol. This is how the FieldServer converts Modbus RTU data to KNX data.
Just a guess here but thinking that the KNX OmniPro device has connectivity for Modbus.
IE: OPII ==> KNX ==> modbus stuff
Once defined in the OPII then it is just another device to control.
Modbus has been utilized commercially for many many years now. While it is toted as new technology for the home; it is. Commercially it has advanced now to beyond modbus and to bacnet or whatever these days.
The analogy here is sort of relating to airplane controls / automobile controls still utilize bus standards developed in the 1940's.
It is changing these days. I was a bit involved in the airline stuff and typically there was a want of an upgrade to the old bus standards but also there was that whole thing about breaking something that has been know to work fine for many years. (the whole front of the cockpit versus rear of the cockpit stuff or issues...well and keeping it separate).
