1. General Information

1.1 BACnet MS/TP Introduction

BACnet is a data communications protocol for Building Automation and Control Networks.

BACnet Master Slave Token Passing (MS/TP) protocol is used to relay and exchange

information between building devices. BACnet MS/TP is a based on BACnet standard protocol

SSPC-135, Clause 9. BACnet MS/TP is a peer-to-peer, multiple master protocol based on token

passing. A token is information packets in the form of a pulse signal that is passed between

devices on a network. BACnet MS/TP is exclusive to BACnet and can be implemented using the

EIA-485 signaling standard. This is a shielded twisted-pair (STP) LAN operating at speeds from

9600 bit/s to 76800 Kbit/s. This LAN type is particularly suitable for single controller and low cost

communications.

1.2 Modbus TCP Introduction

MODBUS/TCP is a variant of the MODBUS family of simple, vendor-neutral communication

protocols intended for supervision and control of automation equipment. Specifically, it covers the

use of MODBUS messaging in an “Intranet” or “Internet” environment using the TCP/IP protocols.

The most common use of the protocols at this time are for Ethernet attachment of PLC’s, I/O

modules, and gateways to other simple field buses or I/O networks.

1.3 About GW-2139M

GW-2139M is a network gateway allowing Modbus TCP client devices to be accessed

BACnet MS/TP network as a BACnet MS/TP master. The BACnet Master Slave Token Passing

(MS/TP) protocol is used to relay and exchange information between building devices.

GW-2139M contains a large number of BACnet objects (AI, AO, AV, BI, BO, BV, MSI, MSO, MSV)

gives you 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 using ICPDAS Utility.
