Modbus Server – BACnet Client
TM
Intesis
Points definition
Every point defined in Intesis has the following BACnet features associated to it:
Feature
Description
BACnet Device
BACnet device to which belongs the point, from a list of BACnet devices that can
be defined in Intesis (up to 16).
For every BACnet device defined, a virtual signal is created automatically in Intesis
to inform about the communication with the BACnet device, this signal is available
also from the Modbus interface like the rest of points.
BACnet object type BACnet object type for the point. It can be one of the following BACnet object types
supported by Intesis:
AI = Analog Input.
AO = Analog Output.
AV = Analog Value.
DI = Digital Input.
DO = Digital Output.
DV = Digital Value.
MI = Multistate Input.
MO = Multistate Output.
MV = Multistate Value.
LOOP = Loop
ACUM = Accumulator
Consult documentation of BACnet device(s) to integrate for information about BACnet object types of
the points desired to integrate.
BACnet object
BACnet object instance for the point on the external BACnet device.
instance
Consult documentation of BACnet device(s) to integrate for information about BACnet object instance
of the points desired to integrate.
Note that configuration tool used with Intesis enables for discovery of existing BACnet devices in the network, as well
as their BACnet objects and types, which can be later directly added in configuration. This facilitates the process of
choosing suitable parameters above for every BACnet object on every BACnet device to integrate.
3 Modbus interface
Description
Intesis acts as a slave device in its Modbus interface, this interface can be the Ethernet port (if using Modbus TCP),
or the EIA232/EIA485 ports (if using Modbus RTU). To access the points and resources of the Intesis from a Modbus
master device, you must specify as Modbus register addresses, those configured inside Intesis corresponding to
BACnet signals. See details below in this document.
The Intesis can have Modbus RTU mode active, Modbus TCP mode active, or both modes active at the same time.
Functions supported
This part is common for Modbus TCP & RTU.
Modbus functions 01 and 02 (coils and digital input registers) can be used to read Modbus registers.
