Changing the Preset Value of a Counter Instruction by

Using Ladder Logic

You can change the preset value of a counter instruction without having to edit the

instruction in the AutoMax Ladder Editor. This is useful for frequently loading different

preset values into a counter.

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 counter preset

value.

Step 3.

In the Out output, enter the name of the counter's preset input

(name.CPreset).

Step 4.

Condition the EN input of the MOVE instruction so that the new counter

preset is loaded into the Counter instruction.

Tip

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

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

and place the result in counter's preset input (name.CPreset).
