Operand Summary - Automatic Data Capture

Example - Recording into An Array
CDS-3310
description
Selects up to four arrays for data capture. The arrays must be defined with the
DM command.
Selects the type of data to be recorded, where type1, type2, type3, and type 4
represent the various types of data (see command reference). The order of data
type is important and corresponds with the order of n,m,o,p arrays in the RA
command.
The RC command begins data collection. Sets data capture time interval where
n is an integer between 1 and 8 and designates 2
optional and specifies the number of elements to be captured. If m is not
defined, the number of elements defaults to the smallest array defined by DM.
When m is a negative number, the recording is done continuously in a circular
manner. _RD is the recording pointer and indicates the address of the next array
element. N=0 stops recording.
Returns a 0 or 1 where, 0 denotes not recording, 1 specifies recording in progress
Returns a 0 or 1 where, 0 denotes not recording, 1 specifies recording in progress
Returns address of next array element.
