If you go online monitoring you will see the status of the inputs and outputs on both the full screen monitoring screen as well as the ladder program.

You can only force an output on/off by right-clicking on the "output" on the online monitoring screen.

Hi thanks,
My intention is to monitor changes happen in ladder and send command in serial port to notify.

You mean to monitor the status of the I/O? YOu can use host link command that you send from the serial port to the PLC. Please refer to Chapter 14 of the PLC User Manual.
