Example The following example shows two different block programs controlled by
CIO 000000 and CIO 000002.
The first block executes one of two additions depending on the status of
CIO 000001.This block is executed when CIO 000000 is ON. If CIO 000001 is
ON, 0001 is added to the contents of CIO 0001. If CIO 000001 is OFF, 0002 is
added to the contents of CIO 0001. In either case the result is placed in D00000.
