Campbell Scientific Array I/O Addressing

Analog and digital tags that are connected to a Campbell driver tag require a I/O address format specific to the device. The addresses contain two identifiers: an Array ID (AID) and an index into the array. The description of these elements is beyond the scope of this document, but can be found in the Campbell Scientific documentation.

The format is as follows:

Aaa-ii

Where

A - Denotes the address as an array read

aa - Defines the array number

ii - Defines the index number in the array

For example, if the user wishes to access AID129, element 5, the appropriate string used in the address field of any Analog or Digital tag would be "A129-5".
