Appendix A.2. Using the Carrier Datalink Driver to Obtain Field Names
The Carrier Datalink driver can be used to obtain a list of variable names for a given table using the following Map Descriptors. It
is recommended that these Map Descriptors are removed from the configuration after the variable names have been obtained as
they will consume resource and processing time.
The following example illustrates a Map Descriptor which reads a table and dumps the response in ASCII format to a Data Array
which can be browsed using RUINET (Refer to RuiNet Manual)
Data_Arrays
Data_Array_Name,
Data_Format,
Data_Array_Length
DA_DUMP , BYTE , 2000
Map Descriptors
Map_Descriptor_Name,
Data_Array_Name,
Data_Array_Offset,
Function,
Node_Name, Length,
Scan_Interval,
Table_Name
Field_Name, Storet_As
Md1 , DA_DUMP , 0 , rdbc , FAN01 , 1000 ,
5.0s, DISPLAY , EVERYTHING, Ascii
This is what tells the driver to dump the
table, its variables names and variable
descriptions in ASCII format.
The s=data array DA_DUMP has been
defined with format BYTE. When viewing this
table with RUINET display the array in
‘STRING’ format so that you can read it.
