The BACnet MS/TP Integration Kit for PAC Project enables your Opto 22 PAC system equipped with a SNAP-PAC-S1 or SNAP-PAC-S2 controller to communicate with a BACnet MS/TP network via RS-485. BACnet is a communications protocol for building automation and control networks. MS/TP is a Master-Slave/Token-Passing specification of BACnet.

The integration kit contains the BACnet_Protocol and Master_Sub charts, which contain everything you need to use the BACnet MS/TP protocol in your own PAC Control strategy. It also includes a VAV Controller Polling example strategy that polls from 1 to 45 VAV (Variable Air Volume) controllers.
