Pass value two textbox's from one variable value

Question

I have an encoder connected from Siemens PLC with data block "DB1.DBD56".

My problem is, the two textbox has the same result or value.

Scenario:

Read Before 1seconds and Read After 1seconds

I want the result like this:

Here's my solution.

Only revised the PLC ladder as stated my replied at comment section.

My C# program nothing changes.

Sharing my basic state machine code

#region ONE CYCLE PROCESS
private void timer_OneCycleProcess_Tick(object sender, EventArgs e)
{
    switch (command)
    {
        case "IDLE":
            command = "BEFORE";
            break;

        case "BEFORE":
            before();
            command = "AFTER";
            break;
        case "AFTER":

            after();

            prev_result();

            read_maintenanceCounter();

            read_outputCounter();

            command = "SAVE";
            break;

        case "SAVE":

            command = "STOP";

            save();

            save_history();
            break;
        case "STOP":
            timer_OneCycleProcess.Stop();
            plc_s7_1200.Write("DB1.DBX38.0", 0);
            break;

        default:
            break;
    }
}
