HMS Industrial Networks' Anybus CompactCom Module
HMS Industrial Networks releases Anybus CompactCom for BACnet/IP. This is a network communication module which can be embedded into air conditioning equipment, pumps, ventilation devices etc. enabling communication with the BACnet/IP network. The Anybus CompactCom BACnet/IP includes an integrated 2-port switch that makes it possible to connect the device to the network in normal fieldbus style (daisy chain) rather than connecting all devices through an external switch. The Anybus CompactCom module acts as a server (B-ASC) on the BACnet/IP network. It is available with and without housing and is about the size of a compact flash card.
