I can see how to move from the math function to the counter, but not how to get a value from the screen into the counter. The only variables listed in the math block are all timers. How do I do this using ladder?

In the parameter "Start Value" can only written by: - LOGO! or TDE Display. - from remote (external HMI, other LOGO!, PLC etc.).
