Timer and Counter Instructions Section 3-5
Be sure that the words specified for the Completion Flag and PV (D1, D2, and
D2+1) are not used in other instructions. If these words are affected by other
instructions, the timer might not time out properly.
Example When timer input CIO 0.00 is ON in the following example, the timer PV (in
D101 and D100) will be set to the SV (in D201 and D200) and the PV will
begin counting down. The timer Completion Flag (CIO 200.00) will be turned
ON when the PV reaches 0000 0000.
When CIO 0.00 goes OFF, the timer PV will be reset to the SV and the Com-
pletion Flag will be turned OFF.
