Fixing incorrect display of special characters on the PLC web and disabled BACnet server
After runtime upload, some Linux-based PLCs may show incorrect display of special characters on the web and their BACnet server is disabled. This is caused by a missing record in the configuration script which is run after the runtime update. Both problems can be fixed easily.
It is necessary to add the UTF-8 character set in Linux by playing the nginx.conf file and allow access to UDP port 47808 in the firewall.
