FS-8700-49_Data_Aire_DAP 1. Page 4 of 48 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).

Page 10 of 48 Driver Related Map Descriptor Parameters Column Title Function Node_Name Name of Node to fetch data from Data_Type Length Data type Length of Map Descriptor Address Starting address of read block Only required when the function is a Read (rdbc). Tells the driver to poll the device for all the data that is available. The data is device specific. Other uses of this parameter are discussed in Appendix B .
Map Descriptor Example 1 - Everything Page 11 of 48 The setpoint is obtained from this Data Array. Function, RDBC, Node_Name, Unit1, Node_Name, Unit1, Address 0, Example. If unit1 is a Chiller then the above Map Descriptor will not function correctly as it can only be used to write to unit types 7,9,14,15. Select the data field from Appendix B.3. Ensure that the keyword can be written to the unit type identified as unit1. Function, WRBC, DA_Func, Everything, Scan_Interval 2.
Data_Array_Offset, 0, 1, Node_name, Unit1, Unit1, Address, 0, 0, Length, 1, 1, DA_Field, nom_h_setpt, t_setpt, DA_Assoc, 2, 2, Scan_Interval 120s The association is made using the DA_Assoc parameter. Use unique positive integers. Omitting the DA_Assoc parameter when using ‘passive’ Map Descriptors will produce ambiguous results. Associate the passive Map Descriptor to the active (wrbc) Map Descriptor. In this way the driver will use only one message to write to the device.
FS-8700-49_Data_Aire_DAP Page 13 of 48 Appendix A. Data Tables Appendix A.1. Data Table 1: Array Locations of ‘Everything’ In the following table the array location indicates the offset in the Data Array at which a data field can be found. (This offset is relative to the offset specified in the Map Descriptor) The columns headed 2, 3 … indicate the unit types for which the data fields are available.

FS-8700-49_Data_Aire_DAP Page 25 of 48 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.
FS-8700-49_Data_Aire_DAP Page 26 of 48 Appendix B. Advanced Topics Appendix B.1. Additional Driver Specific Map Descriptor Parameters The driver offers advanced configuration by adding to and extending the Map Descriptors specific to the Dart Serial Driver. Column Title DA_Func* DA_Field* Function Specifies the Data Aire Command/Query function to be used. Use a function appropriate to the type of Server (DAP/Chiller/DAP80) and the type of data required.
FS-8700-49_Data_Aire_DAP Page 27 of 48 Appendix B.2. DA_Func Parameter - Permitted values. The driver supports a limited subset of the Dart Poll & Response Functions. The selection of the sub-set is based on the identification of useful & practical functions. In addition to the ‘Everything’ keyword indicated in chapter 4 the following specific query functions are implemented. Func.

The value found at offset 0 is the zone number. The value found at offset 1 is the inhibit code which is used to inhibit/run units.
FS-8700-49_Data_Aire_DAP Page 33 of 48 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.
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.

FS-8700-49_Data_Aire_DAP Page 39 of 48 The driver uses the Data Array DA_DAP _STATS (in this example) to store driver specific statistics in the dap-stats Map Descriptor. Only one of these Map Descriptors may be specified per FieldServer. The driver stores the following data.
FS-8700-49_Data_Aire_DAP Page 40 of 48 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.
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.

FS-8700-49_Data_Aire_DAP Page 46 of 48 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.
FS-8700-49_Data_Aire_DAP Page 47 of 48 Appendix F. Write Through’s This driver provides very limited Write Through Support. It is possible to generate a Write Through by writing to the Data Array used in a read Map Descriptor where the DA_Func keyword is ‘Everything’ provided that the write through results in Dap80-Menu command being sent to the DAP device. This is true for variables whose offsets are between 899 and 1086 in Section Appendix A.
