[?): why PLCSIM V14 forces data to HMI?

[m_eijie]

hi
i have a problem with plcsim and HMI simulation.
i made a simple start/stop program in TIA V14 and simulated it in plcsim,works fine.
also a simple wincc project created with tag management and some button that indicates start/stop and motor output state.
when i start plcsim and hmi simulation at one time, values [like bit state] that are in plcsim forces to hmi and when i clicked a start button in hmi, nothing run
but when i set start bit in plcsim, output activated and indicators in hmi blinks on.
what is problem in my project?

thanks for yours attention.

Use "Compile Software (rebuild all)" for your HMI and try again

thank you much. my problem solved.i've changed I/O bits status like I0.0 from HMI side, so that's wrong. i must set or reset a memory bit like m0.0 from hmi for start or restart a motor output.
