Data Aire Description
The Data Aire Driver is capable of direct connection to a network of Data Aire DAP devices.
The FieldServer is connected in a RS-485 loop topology. Two FieldServer ports are required
per loop. The driver is an active client. All data is obtained by poll & response.
Connection to a DART is not supported by this driver.
The driver may be configured very simply (See Section 4.4). A number of advanced
configurations are also available and are described in Appendix B. The driver supports the
common message formats for common Data Aire DAP devices. A list of the supported
messages is provided in the manual.
The information that follows describes how to expand upon the factory defaults provided in the
configuration files included with the FieldServer.
1.1.
Performance Issues - DARTIII only
Data Aire communication is based on a very low baud rate. In addition inter-message timing
constraints and overhead requirements for active messages in a Dart configuration add
significant time to each transaction. It is not possible to write a setpoint to a device until the
device has been successfully read, and the result of the write will not be seen until the next
read is complete. The result of a write may not be seen for some time due to slow
communications and significant inter poll delays.
1.2.
Data Alarm Network Module Network LED Operation
DAP-II units communicate with a DART unit by using a Data Alarm Network Module. This
module provides a RS-485 communications link. Installed on the card are several LEDS.
The table below explains how the LEDS appear under normal (correctly functioning)
operation.
LED
LED Appearance
The Network Module has a blown fuse detection circuit. If one (or more) of
the fuses has an open circuit, then the FUSE LED will be lit. Normally, this
LED is dark.
FUSE
Communications signals enter and leave the Network Module. These LEDS
reflect the communications activity. When first powered up, both LED's will
be lit and the illumination will be steady. As the DART communicates with
the network, both LED’s will begin to flicker in unison. All of the Network
Module LED’s will flicker at the same time.
DS1 &
DS3
At some point the DART will send a communication message to a specific
network-connected DAP-II that requires a reply to the DART. If the message
is received without error, the DAP-II will reply by engaging a relay on the
Network Module and transmitting a message. When this happens the
NETWORK LED will come on. Whenever a NETWORK LED is seen to
come on it means that the communications into the Network Module is
satisfactory. It is still possible to have a wiring problem downstream of the
module that prevents the message from being received by the DART

Configuring the FieldServer as a Data Aire Client
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
instruction manual. The information that follows describes how to expand upon the factory
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files
provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a Data Aire Server
4.1.
Data Arrays/Descriptors
The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for Data Aire communications, the driver
independent FieldServer buffers need to be declared in the “Data Arrays” section, the
destination device addresses need to be declared in the “Client Side Nodes” section, and
the data required from the servers needs to be mapped in the “Client Side Map Descriptors”
section. Details on how to do this can be found below.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

Appendix A.3. Data Table 3 - Unit Types
When the driver reads everything from a device it must first obtain the device’s unit type so
that it can determine what other data is available. Once the unit type is obtained then the
driver updates the ‘Unit-Type’ field visible on the node screen of the RUIDebug program.
The unit type is also available in the Data Array defined in table 4.4.5.1.
The following table lists the unit types that can be processed by this driver.

With the exception of the Unit-Talk transmission of this command, these are nodeless
commands to allow the units time to switch their mechanical command. When using any of
these special commands no other DA_* fields need be specified.
All-Listen instructs the all units in the network to switch their relays to the listen position.
Those units already in the listen position will do nothing. Those in the talk position will first
echo the all-listen command and then switch their relays to the listen position. A pause of
0.15 seconds is required after the relays.

Special
Appendix B.4. DA_Method Parameter Values and Notes
The DA_Method specifies a method for interpreting a range of bytes when the DA_Field=special.
Method #
Description
Each byte is valid when it contains only one of the following ASCII characters.
{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F }
Each byte being parsed is considered to be a hexadecimal digit with the most
significant digit being the left-most byte.
Method 1:
The four bytes 30 31 32 33 (hex) are therefore interpreted as the hexadecimal
number 0123 and the decimal value is equal to 291.
As method 1, but used for humidity's and temperatures which are transmitted as the
number of tenths of a unit – Thus the 4 bytes yield the decimal number 29.1 °F/%.
Each byte is regarded as containing a hexadecimal digit in ASCII format.
Example: incoming byte contains 41(hex). -> regarded as the hexadecimal digit 'A' in
ASCII format.
Method 2
Method 3
The hex digit is converted to a series of 8 bits. In this example the bits are 00001010
with the msb being the left-most.
As Method 3 except that the decimal value of this digit is written to the Data Array. In
this example the number 10 would be written to the Data Array.
There is no translation - the raw bytes are written to the data array.
Processes an array of elements using method 1 translation. The raw data being
parsed is considered to consist of DA_elecnt elements each consisting of DA_bytecnt
bytes.
Method 4
Method 5
Method 6

Appendix C. Troubleshooting Tips
Appendix C.1. Bad Values
In the event that the driver cannot correctly decode the raw bytes it will generally write a
value which indicates bad data. In most cases the indicating value is -1 or 65535
(depending on data type). When setting bits for status fields the driver will not write new
data to the array if the incoming byte is invalid. Consult the error log for indication of this
type of problem.
Example: Valid ASCII digits are 0...9, A...F. If a byte is being parsed and a hex digit is
expected but not found then the driver considers this an error and writes the bad value
indication OR produces an error message when the bad value indication cannot be used.
Appendix C.2. Dead Nodes
When a node is absent or dies, the driver may go idle and stop communicating with all other
nodes. This problem is specific to the Data Aire devices.
Appendix C.3. Noise
A high percentage of responses on the secondary port are preceded with noise. The driver
is generally able to filter this noise because legitimate characters in a response are limited to
the ASCII character set and a few control characters. The driver does not filter noise in the
middle of a message. Thus the message will fail (generally as a checksum failure) when
there is noise in the middle of a message. This is normal for most drivers.
Appendix C.4. Ignored Messages
Ignored messages which are messages sent by a DAP/DART for which the driver cannot
find an appropriate Map Descriptor are reported by the driver. This simply indicates that a
message containing information that is not required is being discarded. The current version
of the driver ignores a few messages relating to the status of the DART device. Later
versions of the driver will be capable of storing these messages and the number of ignored
messages will decrease.
Appendix C.5. Driver limitation
Unable to reset run times.
Appendix C.6. Baud Rate.
Rev 9.5 of the DAP firmware changed the baud rate from 2400 to 9600. All units must have
the same baud rate on the network. The customer should check the firmware version of
each unit and record these in a table. FieldServer recommends that all units have the same
version due to the fact that instability between different versions has been experienced.
Appendix C.7. Wiring.
This must be completed exactly as specified by Data Aire. Variations in the wiring invariably
causes problems. The wit=ring/installation guide is available from Data Aire.

FS-8700-49_Data_Aire_DAP
Page 34 of 48
Appendix C.8. Stuck Unit.
Communications on the DAP units requires the operation of a mechanical relay. This can
get stuck. The Front Panel menu of each DAP unit allows a user to execute a diagnostic
test of the comms board. The customer should execute this test and use the Data Aire
installation guide to resolve any issues. Typically a failed unit requires replacement. A
single failed card will fail the whole network. The FieldServer sends polls on the primary
port and expects responses on the secondary port. The fact that we get back a copy of the
poll message on the secondary port does not mean that the units are operating correctly
since this is possible when the units are stuck in pass thru mode.
Appendix C.9. Number of Units
Up to 250 DAP devices can be connected to a FieldServer using the DAP driver.
Normal RS485 network considerations apply - these limit the number of units based on the
load of each node.
•
•
For unit loads only 32 devices per network can be used.
For .25 unit loads 128 devices can be used on one network segment. If more than 32
full unit loads are required then the network must be segmented and connected via a
repeater
•
It may be necessary to use a repeater if total RS-485 length exceeds 1000ft.
It is recommended that tests are performed with a single or few units.

Appendix D.1. Exposing Driver Statistics
In addition to the standard FieldServer communication statistics described in the FieldServer
Configuration Manual, the DAP Driver can also expose some driver statistics by writing data
to a Data Array. A special Map Descriptor named "dap-stats" is required.

Appendix E. Writing data to DAP Devices
Appendix E.1. Background
The variables in a DAP device are not individually addressable. When a DAP device is read
a data composite is returned and the driver extracts the required data. When data is written
to a DAP device it is not possible to write a value to one individual data element such as a
temperature setpoint. Rather, the DAP devices requires the complete data composite (all its
variables, states, settings) be written at once. This makes the setting of a setpoint a
complex operation for the driver.
It involves the following steps
a. Read the device, obtain a complete set of data and store (internally in the driver.).
b. Use this stored data to form the basis for a write. Modify the data with the data the
user wishes to set.
c. Write the modified data composite back to the DAP device.
Thus to complete a 'write' operation successfully, the device must be read successfully. If
the read has not been completed then the write operation will be abandoned. The driver
prints messages to the error logs and records a NODE_OFFLINE stat under these
circumstances.
Appendix E.2. Associated Map Descriptors
When writing to a DAP device it is possible to associate Map Descriptors using the
DA_Assoc parameter. T his is straightforward using WRBC or RDBC. When using WRBX
to trigger the writes on change, however, the function of the associated Map Descriptors
must be passive if the upstream device block writes the data. The following diagram
outlines the required strategy.

FS-8700-49_Data_Aire_DAP
Page 41 of 48
Appendix E.3. Starting/Stopping DAP devices
The DAP-Config command is an exception to the above notes. A read is not required.
The DAP Config command is used to turn off/on DAP units. The Command uses two
consecutive array elements. The first is the zone, the second is the inhibit command. Valid
zones are 0-63.
If any inhibit bit (bits 0-5) is set then the unit will not run. If bits 0 to 5 are off then the unit
will run. Bits 6& 7 are used for display only on the DAP panel.
0x01 - Inhibit Cooling
0x02 - Inhibit Heating
0x04 - Inhibit Humid
0x08 - Inhibit Dehumidification
0x10 - Inhibit fan
0x20 - Reserved
0x40 - Network Standby - Display on panel (only has no effect on unit)
0x80 - Network off inhibit is active - display only - no effect on operation
This function should be used as a wrbc/x. When the driver encounters this command it
reads the associated Data Array, loads the two elements found at the array offset into the
message and transmits the message. The driver does not set any Data Array elements to
confirm that the command concluded successfully.
Additional information is provided in Appendix B.10
Appendix E.4. DAP Unit Errors
Dap-Stat Query
The following table provides information on the storage of errors obtained in response to the
Dap-Stat Query. Note that the errors are stored two ways – One storage method stores 8
alarm bits at a time in a single array element (stored as byte values) – The other method
stores each alarm at a different location in the Data Array.

Appendix E.5. Using DA_Assoc correctly with Writes/Toggling Values
Association of Map Descriptors can result in zero’s being written to the DAP device. The
following information can help to prevent this problem. When Map Descriptors are
associated using the same value for the DA_Assoc parameter then the associated Map
Descriptors are all processed before a write is sent to the DAP unit. A write to a DAP unit
writes a complex set of data – it is not possible to write a single variable’s value to a DAP
device. Each associated Map Descriptor is used to update the complex set of data that will
be written.
Consider the following Map Descriptor fragments
Data_Array,
DA_SETPOINTS,
DA_SETPOINTS,
Data_Array_Offset,
0,
1,
Function,
WRBC,
passive,
Node_Name,
Unit1,
Unit1,
Address
0,
0,
DA_Field,
1,
1,
DA_Assoc,
nom_h_setpt,,
t_setpt,,
Scan_Interval
120s
120s
If an upstream device writes a value to DA_SETPOINTS Offset 0, when the write is done the
values of DA_SETPOINTS Offset 0 AND Offset 1 are both used to build the complex data
set since the Map Descriptors are associated. If the upstream device has never set the
value of DA_SETPOINTS offset 1, the value will be zero and hence a value of zero would
be written to the DAP’s Temperature Setpoint.
This could be avoided by not associating the Map Descriptors. This will, however, result in
extra write messages being sent to the DAP device. The extra messages could be avoided
by changing the wrbc to a wrbx. If you do this you must still consider the effects of
association and in this case it may be best to have each Map Descriptor defined as a wrbx
with a different value for DA_Assoc.

Appendix F. Write Through’s
