  • Simple data translation allows you to manipulate data as it passes between protocol


The ICP DAS GW-2439M is a network gateway that allows Modbus TCP client devices to access BACnet/IP network as a BACnet/IP client. The BACnet/IP protocol is used to relay and exchange information between building devices.

The ICP DAS GW-2439M contains a large number of BACnet objects (AI, AO, AV, BI, BO, BV, MSI, MSO, MSV) gives user the flexibility in mapping Modbus TCP registers to any combination of BACnet objects. BACnet interoperability building blocks (DS-RP-A, DS-RPM-A, DS-WP-A, DS-WPM-A, DM-DDB-A, DM-DOB-A, DM-DCC-A, DM-RD-A) are supported. All the data transfer is configurable via the ICP DAS Utility.
