I'm looking to do a quick proof of concept showing Opto22 hardware communicating to a building chiller system via BACNET. I'd like to do this using the lowest cost option and was wondering if I could use the SoftPac to talk directly to the chiller via BACNet. From looking at the docs it does not look like I can talk BACNet serial directly from the PC so I may need to use one of the BACNet protocol routers to convert protocols to Ethernet and then hook my PC directly to the router via Ethernet and then from the router to the chiller controls via RS485 BACNET.
Am I on the right track? Is there a better way to accomplish this?
Thanks in advance for your help.
