required.

 

 

Specifies the data field to be retrieved from

 

 

the Server device. Servers are only

 

 

capable of responding with a data

 

 

composite consisting of many data fields.

This field is used to make the association

 

 

between passive and active (rdbc/wrbc)

Used only for connection to DART’s.

 

Da_Freq

Specifies in milliseconds the intervals
