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:
Reboot the PLC. The web shall display all UTF-8 special characters correctly and the BACnet server shall be available now.
Password change at Linux-based PLCs (IPLC500, IPLC510, MXPLC-L, mark…) used to be “sharkXXXX”, where XXXX were the last four digits of the PLC serial number. Now the password is the number stated at the PLC label as “code:”. The process stations affected are easy to recognize according to the “code:” item at the device label (see image). The user is root, as before.
