A reset causes the HMI to re-read its configuration file. You can reconfigure by editing the HMI configuration file and issuing a reset request. However, the ports assigned to the HMI are not reconfigured on a reset. The HMI must be stopped and restarted to change ports.
All existing application connections are preserved during a reset.
