[Example] Error Detect Circuit of Returning Equipment [TRTG]
(1) Operation
Detects missing item on conveyor based on a known time between detection of items. When item is
detected on Input P0002, Timer T0005 begins counting down from the preset and Bit Output M0002 is
turned ON starting the process. If another item is not detected within the preset time, Timer T0005 resets
and turns OFF M0002, stopping the process. When P0002 is turned ON again, the process restarts.

(3) Program
(4) When Bit P00002 transitions to ON T0005 begins counting DOWN from the preset and Timer Bit T0005
turns ON, turning ON Bit M0000 (M000, Bit 0). P00002 will remain counting DOWN if P00002 turns OFF.
Bit T0005 will remain ON. If T0005 reaches 0 (Zero) counts, Bit T0005 will turn OFF and de-energize Bit
M0000, stopping the process.
