I am looking for a Gateway solution for the following:
I have a HVAC control system with Two NCRS Controllers each with 4 trunks. The trunks seem to have either RC controllers or Smart II Controllers. There are approx 100 Smart II of various types and 25 RC Controllers. Front end is Desigo which we want to bin.
Has anybody tried to bring this into a modern front end system? Is there a BACNET, LON, OPC or even Modbus Gateway that anybody has used. The system is stable, and I really don't want to replace it.
Any help would be appreciated.
