Gateway for the integration of Modbus TCP slave devices into BACnet/IP control systems. Models available for this gateway, with their following Order codes: IBOX-BAC-MBTCP-100 Tiny model with capacity of 110 internal datapoints. IBOX-BAC-MBTCP-A Basic model with capacity of 500 internal datapoints.
From now on, and with the aim of easy the read of this document, the words "gateway" or “IntesisBox” are used instead of IntesisBox BACnet/IP Server - Modbus TCP Master. Any other use of the word "gateway" not meaning IntesisBox BACnet/IP Server - Modbus TCP Master will be specifically indicated.
1.2 Functionality The integration operation is as follow: From the Modbus TCP system point of view, after the start up process, IntesisBox reads continuously the points configured to be read in the Modbus TCP slave devices, and updates in its memory all the values received from the Modbus TCP system.
Number of Modbus TCP Slave devices TCP Slave devices supported by the device There are different models of IntesisBox BACnet/IP Server - Modbus TCP Master, with different capacity every one of them. Tiny model with capacity of 110 internal data points.

Also the data encoding used for 16 bits registers (big-endian or little-endian) can be configured in IntesisBox Modbus interface. This is the byte order for data encoding (MSB..LSB or LSB..MSB). This data encoding, although is specified as big-endian in Modbus protocol specification, it varies depending on manufacturer/type of slave.
3. Quick Setup 1. Install LinkBoxBacnet. Details in section 5 2. Install IntesisBox in the desired installation site (DIN rail mounting inside a metallic industrial cabinet connected to ground is recommended). 3. Power up and connect the communication cables. Details in section 4.
