All Mode

In All mode, all the specified elements in the array are operated on before continuing on to the next instruction. The operation begins when the instruction’s rung-condition-in goes from false to true. The position (.POS) value in the control structure points to the element in the array that the instruction is currently using. Operation stops when the .POS value equals the .LEN value.

The following timing diagram shows the relationship between status bits and instruction operation. When the instruction execution is complete, the .DN bit is set. The .DN bit, the .EN bit, and the .POS value are cleared when the rung-condition-in is false. Only then can another execution of the instruction be triggered by a false-to-true transition of rung-condition-in
