The LTX-VCI can handle A/C interfaces with up to 64 indoor units. Many LTX controllers are
only designed to handle 16 units, therefore the VCI can serve data to up to 4 LTX controllers in
order to allow access and control of all units.
Interfaces that the LTX-VCI are compatible with are associated with a Device Interface Sheet
within this datasheet that describes specific details of interfacing, lists what functionality is
available and provides fault code references. The current version of the LTX-VCI is compatible
with the following device interfaces:

Engineering
Engineering is a two step process, on one side connecting the VCI with the air-conditioning
Interface, on the other connecting the BMS control system via a suitable LTX controller.
To engineer a specific system, follow the instructions in this datasheet to set up the linkage to
the BMS interface and perform general configuration of the LTX-VCI. Refer to the relevant
Device Interface Sheet within this datasheet for the relevant manufacturers product, this will
provide product specific details of the available functionality and specific configuration
information. Device Interfaces Sheets are specific to the LonWorks Program ID of the
interface. If the program ID is different from that in the Device Interface Sheet then contact
RealTime as there may be compatibility issues.
The system must be engineered by a suitably trained LonWorks integrator using the correct
engineering tools. Engineers new to engineering RealTime products should contact us for
additional information. The LonWorks functional profile for the VCI is available at the rear of
this datasheet.
Air-Conditioning Interface
Note: Before the system is installed it is advisable to establish the unit addressing
methodology being used in the system. As a general principle it is recommended that
units are addressed from unit ‘1’ (the lowest possible address) upwards with no gaps in
the addressing scheme. Schemes that start the addressing at higher values and have
gaps in the addressing scheme are liable to create problems in the interfacing and
control of the system.
Firstly consult the Device Interface Sheet relevant to the system being installed, these are
found in this datasheet. The device interface sheet will provide device specific information on
the device functionality and any special steps that need to be taken during installation and
engineering. The Device Interface Sheet provides the relevant VCI Mode Number for the
device in question, this value configures the VCI to the correct configuration for the selected
interface. The first task in configuring the VCI is set this value in the Node: UCPTVCIMode. If
unsure of the value, setting Node: UCPTVCIMode equal to 0 disables any communication with
the interface. WARNING: Using an incorrect value for UCPTVCIMode can lead to
unpredictable behaviour of the system.
Once the VCI Mode is selected the VCI will be configured to the maximum number of indoor
units for the selected interface, should the actual number of units be less than the maximum
this it is possible to restrict the overall range of units addressed by the VCI by using the
configuration parameters Node:UCPTMinUnitNum and Node:UCPTMaxUnitNum This will
reduce the amount of time required to scan the system in order to produce faster updates of
readback data and will also prevent invalid unit addresses from being processed.
To enable communication between the VCI and the A/C Interface create a single message tag
binding between the tag VCItag on the VCI and the standard msg_in tag on the selected A/C
1
interface using a suitable LonWorks engineering tool.
The VCI should now be communicating with the air-conditioning interface, polling data from the
selected range of units. The VCI will not write any data to the units until it receives control data
from the BMS interface.
1
Message tags in LonMaker for Windows are found on the Virtual Function Block (VFB) of each of the devices. If adding by hand it will
be necessary to drop the VCItag msg_out object onto the VCI VFB and a msg_in object on the a/c interface VFB to make them visible.
Connecting them as normal will bind the tags.

1.3.2
BMS Interface
The VCI consists of four VCI Proxy function blocks that manage data exchange between one
or more BMS interfaces and the A/C interface. Each proxy can be bound to a different LTX
controller in order to allow the control of up to 64 units. In the default configuration the main
proxy, VCI Proxy[0] can be used to directly address up to 64 A/C units. The remaining three
proxies VCI Proxy[1] to VCI Proxy[3] each address 16 consecutive units. The following are the
default address ranges of the units
Function Block
VCI Proxy[0]
VCI Proxy[1]
VCI Proxy[2]
VCI Proxy[3]
Start Unit
1
17
33
49
End Unit
64
32
48
64
If it is necessary to use more than one interface then each interface is bound to successive
VCI Proxies. For example a second LTX interface would be bound to VCI Proxy[1], this
performs a default mapping so that unit 1 in the second LTX corresponds to unit number 17 in
the VCI and unit 16 in the second LTX corresponds to unit number 32 in the VCI.
Each of the proxy function blocks has two configuration parameters UCPTStartUnitOffset and
UCPTEndUnitOffset which can be used to map each proxy to any address range within the
range 1 to 64. If the configuration parameters are set to zero the function block will operate
with default address ranges outline above. These offset values can be used to map units into
the correct address range should a site addressing scheme not begin at 1.
1.3.3
Fault Code Mapping
Existing LTX controllers use an established fault reporting system that allows fault codes to be
translated and reported in various different BMS architectures. To retain backwards
compatibility the current version of the VCI translates manufacturers fault codes into the
established fault code format. In the BMS the LTX can be translated back into the native
manufacturers codes either manually or using suitable lookup mechanisms. Each Device
Interface Sheet provides the necessary translation between LTX and manufacturers fault
codes.

LTX-VCI Iss1.05
In the simplest configuration a single LTX controller is bound to VCI Proxy[0] and can monitor
and control units in the range 1 to the maximum unit count for the LTX controller. Typically this
is to a limit of 16 units, but some new LTX controllers may be able to address up to 64 units.

Operation Notes
Master/Slave Operation
Some Daikin A/C units operate in AUTO with separate heating and cooling setpoints. The
readback values of run-mode and setpoint reflect the actual values the unit is operating to
rather than those initially set by the BMS or keypad. With the LTX Master/Slave operation the
LTX controllers copy the read-back data from the keypad master and write it into the slave
units. If the master unit is operating in AUTO with an initial setpoint of 20 degrees then when it
moves into heating mode the readback data will be 18 degrees, HEAT, and the slave units will
be placed in this state. Hence the slave units will mirror the operation of the master as
expected and will perform the same setpoint transitions as the master even though they will
not be operating in AUTO. It is recommended that the system designer should check that this
functionality is acceptable.

3 Installation Instructions
The LTX is installed as follows
2)
Mount the LTX on a standard symmetric DIN
rail. A clearance of 85mm above and 105mm
below the DIN rail centreline should be allowed
and 155mm horizontal clearance. See the
figure to the right.
Connect the LTX Power connector (black) to a
1.5VA 24Vdc supply. The connection is
polarity independent. Do not power the device
up.

3)
Connect the LonWorks network to the LTX
connector labelled ‘Network’ (orange) using unshielded twisted pair; the connection is
polarity independent. Multiple devices can be daisy-chained.
4)
Daisy-chain the LonWorks connection from the LTX to a pair of screw-terminals
mounted on the DIN rail adjacent to the LTX. This is for engineering purposes and
allows easy access to the network.
5)
Add a network terminator to the LonWorks network if specified.
