Program execution will flow from 2 to 3 to 4 and back to 2 during the 20 s
before "B" is executed, as shown in the following diagram.
Delays execution of the rest of the block program until the specified count has
been achieved. Execution will be continued from the next instruction after
CNTW(814)/CNTWX(818) when the counter counts out.
