Does the TOP Server BACnet driver act as a Client or Server on the network?
Is the driver a BACnet client or server? That is, will it enable my PC to act as a BACnet client, server, or both on a BACnet network?
The driver acts as a client (formerly called a master) only.
However, the driver does support polled requests, and exception requests. Exception requests means the driver can handle unsolicited updates based on a previous subscription (like the OnDataChange between OPC clients and servers).
