This program is
FAST_ACQ.BAS
in the
\EXAMPLES\
subdirectory. It will configure 48 thermocouple
channels, set up the MultiScan/1200 for fast acquisition, and then bring the values into the controller
after the acquisition is complete. From a logic standpoint, the difference between this program and the
SLOW_ACQ.BAS
program is that this
FAST_ACQ.BAS
program reads blocks of data instead of one scan
at a time. This method is usually more efficient in case of fast scan intervals.
