4.4.5Map of How Data Aire Device Data is stored in a Data Array
In the example of 4.4.1 the Fieldserver listens passively for all possible data from the device called ‘unit1’ and stores the data in an array called ‘DA_01’.
The data that is obtained from ‘unit1’ is dependent on the type of device. Irrespective of the device type the arrangement of data, stored in DA_01, is fixed. If a data field cannot be obtained from ‘unit1’ then the array is left with a zero value for that data field.
Table 4.4.5.1: 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. For example: The field ‘d_temp’ can be read from unit types 2,5,6,7,9 but not from any of the other unit types. It is beyond the scope of this manual to describe each field and to indicate valid ranges. Such information should be obtained from the Data Aire Corporation.
‘x’ Indicates Read only
‘X’ Indicates a point that can be read & written. ‘w’ Indicates a write only point.
