We have already fixed some possible problems that could cause this error. If you have older version of firmware than 5.3 on your PLC, update to the last version. You can use either the configuration web https://<PLC_IP_address:8443> or Firmware Updater tool . 

When the problem persists, please, open PLC configuration web and check the checkbox on Debug page. Send this file to  and we will analyze it and look for the reason.
