7.9.1.8 Use of Multiple Scans
CRBasic example Use of Multiple Scans (p. 179) demonstrates the use of multiple
scans. Some applications require measurements or processing to occur at an
interval different from that of the main program scan. Secondary, or slow
sequence, scans are prefaced with the SlowSequence instruction.
