ＢＡＣｎｅｔ标准目前使用两种技术来实现ＩＰ互联ＢＡＣｎｅｔ网络。第一种技术在附件Ｈ中进行了描述，其设备称之为 ＰＡＤ，将ＢＡＣｎｅｔ报文通过ＩＰ互联网传送。第二种技术在附件Ｊ中进行了描述，设备称之为 ＢＡＣｎｅｔ／ＩＰ设备，其作用就是将ＢＡＣｎｅｔ报文封装进ＩＰ帧中进行传输。本文介绍了ＢＡＣｎｅｔ互联网的概念，用ＰＡＤ组建ＢＡＣｎｅｔ互联网， ＢＡＣｎｅｔ／ＩＰ网络的规范，ＢＡＣｎｅｔ／ＩＰ设备和 ＢＡＣｎｅｔ设备组成的混合网络的工作原理。
The BACnet standard currently uses two technologies to implement IP-connected BACnet networks. The first technique is described in Annex H, the device is called a PAD, and BACnet messages are sent over the IP Internet. The second technique is described in Annex J, which is called a BACnet / IP device. Its role is to encapsulate BACnet messages into IP frames for transmission. This article describes the concept of BACnet Internet, the BACnet with PAD, the specification of BACnet / IP networks, and the working principle of a hybrid network of BACnet / IP devices and BACnet devices.
