Description
The BACnet IP-MS/TP slave ekinex® EK-BJ1-TPIP/EK-BJ1-TP-MSTP
gateway is a KNX modular unit for
panel mounting. It allows you to exchange information
with a master device over a RS485 differential serial or
Ethernet network through BACnet protocol. The ekinex
gateway acts as BACnet slave. The information
exchanged over the BACnet network are updated over
the KNX network by means of a twisted pair (TP)
communication cable.
The device manages a two-way data stream: the
BACnet registers can be cyclically read and their value
sent as a communication object over the KNX TP
network through a multicast communication to
configured group addresses. The data update over the
KNX network can be done cyclically and/or on event of
change of the data acquired by the BACnet network.
Likewise, the ekinex gateway can make requests to
cyclically readings KNX communication objects or
acquire their values during data exchange over the bus.
Cyclically or on event of change of the communication
objects, data are written on the Modbus registers of one
or more configured devices.
The ekinex gateway supports the entire Modbus RTU
master protocol with the possibility of reading and writing single and multiple 1-bit registers (Coil and
Status) as well as 16-bit registers (Holding and Input). It
is also possible to read and write multiple registers
containing 32-bit floating point values (IEEE 754 format).
As for KNX communication, 1-bit, 1-byte, 2-byte and 4-
byte communication objects can be acquired: internal
conversion functions allow you to convert the
information from and to 16-bit floating point values
(DPT 9.xxx) starting from integer BACnet registers.
Configuration is performed through a PC application
software which communicates through the integrated
Ethernet port. The application software
CGEKBJ1TPIP/CGEKBJ1TPMSTP is available for
download at www.ekinex.com.
