To change the preset value by using ladder logic

Step 1.

Place a Move Source Data to Destination (MOVE) instruction in the ladder

program.

Step 2.

In the In input, enter the value you want to use as a new timer preset value.

Step 3.

In the Out output, enter the name of the timer's preset input (name.TPreset).

Step 4.

Condition the EN input of the MOVE instruction so that the new timer preset

is loaded into the timer instruction.

Tip
You can also use other instructions that have a double integer output to change a timer

preset. For example, you can use an ADD instruction to calculate a new preset and

place the result in timer's preset input (name.TPreset).
